Pearson-1988 April 17- Bariloche. Arrived yesterday afternoon. Steppe dry and looks winter from the air; rosa mosqueta leaves not yellow yet, poplars not completely yellow. Was met at Ezeiza by two students from La Plata and handed over to them the Aconaemys loaned to Josep Alcover. They are having floods in the pampa, and from the air one sees millions of small ponds but not great sheets of water. Met at Bariloche by Adrian Monjeau. University and schools on strike. Clear, cool, windy. Michael Christie came this afternoon. He had been collecting near Copahue in Neuquen up to 2100 m elevation and brought in two huge Buneomys and one much smaller one that was nonetheless pregnant. See species account. Also Ako longi and Ctenomys probably maulinus. Also a juv. Chelemys with yellow incisors. Christie says that it has been a dry summer, but not extreme. The lake at Perito Moreno dried up completely. There was not much of a snowpack. Cold drizzle in the afternoon. April 18- Bariloche. Morning drizzly windy, even a little snow mixed in. Got the car started, barely. Christie came with references about Buneomys. Looks like there may be two species, a big one and a small one, but the literature is chaotic. Left at 3 pm for Limay. The lombardy poplars are spotty: some almost gone, some not yet yellow. Stopped at the sociabilis tuco place, which is 9.6 km N of the turnoff to Villa Angostura. Considerable sign of digging although not many fresh (but rain may have aged them). Also stopped at 22.0km N across the road and a a few hundred m north of the new trout farm; looked like tuco diggings but none fresh. Then stopped at Arroyo Carbon, which is 30.3 km N of the Angostura turn-off. There is now a big gravel operation at the Arroyo with dozens of trucks etc. I looked for tuco sign along the road where we had seen it before; a few rather old burrows, but not enough to encourage trapping. Weather sunny. Drove a couple of hundred m north of the arroyo and pulled up an old road that goes past some poplar trees. Then put out two trap lines of Shermans baited with rolled oats. 32 traps running through a somewhat marshy area with lots of pampas glass and scattered bushes (Berberis, Colletia, Mutisia, chacay; 15 traps nearer the car mostly near bushes (mostly Berberis). Lots of Acaena, scattered bunchgrass, neneo, Senecio. Wind died at dusk, sky clear. April 19-Two gauchos came riding down the trail and through the secured gate in pitch dark, no moon, about 9 pm. Mostly clear early night, then clouded over; no frost. The older gaucho came back through in the morning- precious grizzled, poncho et4 al-but eyeglasses. He is the puestero on this ranch, La Lipela, and his house is at the alamos along the road south of Arroyo Carbon. The Estancia is owned by a man in Bariloche. See species account (Ctenomys sociabilisfor his comments on the local tucos. Ran traps at 7am: 19 Oryzomys and 10 Akodon longipilis all more or less

adult. A fox barked close around campsite in the middle of the night. Left for Bariloche at 10:30am. Measured kilometers as follows: Arroyo Carbon to the sociabilis site 20.4 km; to the Villa Angostura turnoff 30.0, and to the bridge over the Limay at Nahuel Huapi 32.9. Hence Arroyo Carbon is 32.9km by road N of Nahuel Huapi, call it 30km N. April 20. Michael Christie came by with another specimen of Buneomys; then Patricia Fierro. Caged the live Akodon. April 21. Adrian came by to arrange a lecture date. Left at 3:30 for La Veranada. Cloudy and sprinkly. Still working on the road, no visible progress. The bulldozing has prevented access to our regular campsite across the road from the grid, but one can still drive off into the nire scrub a couple of hundred meters north of the campsite. mThe nires just beginning to turn color; did not see our bamboo clump on the road shoulder. Put out 26 bigt Sher mans baited with oats along a path through the nire/bamboo/berberis clumps. Then along the same line put out 9 steel traps, all in excavated tuco sets. These are the tucos that we have wondered about before, living in little clearings in the nire/bamboo, sometimes piling up dirt around the roots of the nires to make considerable little hills. Frequently there are clusters of up to a dozen feeding holes, mostly plugged but not all. Good open tunnels down a foot or so. Drizzle stopped about sunset. April 22. La Veranada. Scattered clouds overnight and some drizzle. Morning and all day overcast with some drizzle. The 9 steel traps had 3 tucos, the 26 Shermans had 1 Akodon olivaceus, 5 Akodon longipilis, and 1 adult Chelems. At 10 a.m. put out 13 cage traps. During considerable snooping around during the day, saw only three fresh tuco diggings, and I heard none. In fact, I don't recall ever hearing tucos in this area. Lots of strawberry and in the tuco clearings a compositae? ground cover with small leaves like arbutus. April 23. Heard barn owl and maybe screech owl during the night. Morning overcast, no frost. A little early for autumn colors. 26 Sher mans and 12 cage traps had 10 Ako longi and 1 Auliscomys. Nothing more in the 9 steel traps, all still in the same places in tuco burrows. Still no tuco vocalizations. A fox had scented a couple of the traps and moved one of them. The most successful longipilis sets seem to have been at dense columns with bamboo. Mixed flocks of Pygarrhichas and Aphrastura and ?others working through the nire trees. Home at 2:30 p.m., still cloudy. Christie came in evening. April 24. Morning cloudy but soon cleared; sunny rest of day. Cleaned traps and cages, worked on History MS. April 25. Bariloche. Morning clear but then clouded up. Frost. Yellow jackets were flying from their nest in the the shady side of the wall into air 4%C. A second nest is in the same wall only 15 feet away. They are not working

Pearson-1988 3 on the gopher skulls on the balcony. Michael Christie and Marcello Bettinelli came to discuss their revision of Olrog's field guide to mammals of the Southern Cone. Then Arturo Tarak came for a visit. He reports many mice crossing the road at night as he returns from the trout farm at La Primavera (Traful Valley) April 26. Bariloche. Morning clear, temp 0*. Yellow jackets not flying at 9:15, temp still 0. Hummingbird investigated their opening (they were inactive). But at 9:30 with no sun in the whole backyard yellowjackets were going and coming with shade temp of 1° C. April 27. Bariloche. Morning clear, frost, temp on balcony 0° . Yellow jackets were flying at 1*. Left at 10 for Rio Castano Overo and Tronador. Cloudless; but at Pampa Linda there was still frost and ice on shady puddles at 4 p.m. I didn't dare try the last km to the usual campsite on the Castano Overo, so stopped at a rise with a pulloff from the road, big coihues and scrubby bamboo. At 4 p.m. put out 12 cage traps in forest, all of them alio ng fallen logs, then about 14 Shermans mostly along logs through the coihue/lenga/bamboo/Berberis linearifolia. Then about 15 Shermans in the marsh (grass/sedge/Berberis/scrubby little nire. Then about 10 Shermans up a gully above the road. Total about 51 traps. Three buses and two cars on the road in to Tronador (they made a luch stop at Pampa Linda). About a week early for the best autumn colors. A flock of big magellanic woodpeckers were working the trees at the campsite when I arrived. Still a few cows wandering around. April 28. Castano Overo. The 51 traps caught 11 Ako longi, 1 Chelemys, and 1 Ako olivaceus. The olivaceus and one of the longis came from the mallin, the rest mostly along longs in coihue forest although there are a few nire and/or lenga mixed in. Nothing caught during the day. Heavy frost during the night, the day cloudless. The mallin was heavily frosted and stayed covered with frost until after the sun reached it at 11 a.m. This frosting seems to make clear why the three Nothofagus species are distributed as thjey are: deciduous nire in the mallin on the valley floor where it gets heavily frosted; lenga on the upper slopes where it faces heavy snow and cold; and coihue in the "banana belt" on the lower slopes. Picked up five cage traps near camp, replaced them with Shermans, and moved the cage traps nearby to where there seem to be some Geoxus diggings. At dusk a whet-whet (Rhinocryptidae) came into camp and scratched around in the leaves. It makes 3, 4, or 5 scratches with the same foot, swivelling on the other foot, givong its tail a droll waggle. April 29. Night clear, almost full moon. It was much warmer than last night, windy, no frost at all. The trap lines near camp caught only two Ako longi, but those in the marsh caught 1 Auliscomys, 1 or 2 Ako olivaceus, and 3 or 4 Ak longi. The woodsy line above the road across from the marsh caught 1 Chelemys and 1 Ako longi. The forest on this line and around camp contains lenga and

coihue. The autumn colors are much stronger after that one cold night. Broke camp at 11 and drove to the cascada and bridge just short of the Ventisquero Negro, then drove back to Bariloche at 4. There seemed to be about 4 cars and 3 carryalls of passengers: the sum total of tourists to see Tronador! April 30. Bariloche. Adrian came to talk about his thesis. Then Patricia. They jangled. May 1. Dinner with Gallopins. Built travel cages for Akodons. May 2. Left with Adrian for Chalhuaco at 2 p.m. Roadwork at the "Caracol" prevented going all the way up, but camped in good lenga/amancay half-way up. I put out 13 cage traps, 32 Shermans, and 4 steel traps, all along logs. Adrian put out 36 Shermans, mostly aloing logs, and in clusters. Weather clear, cool,, the autumn leaves not quite optimum yet. May 3. Night clear calm, 2 days past full moon. Heard no owls. We are camped in a clearing about 50 m across with lots of amancay, berberis, and current bushes. Yesterday evening I found fresh cuttings of grass and geranium, so put three street traps along a log nearby. Just after dark one of these traps caught TWO Akodon longipilis at the same time, and when reset soon caught a big Auliscomys. Also an Ako longi in a Sherman. Some ice in water kettle but no frost here, but frost down on the nire flats. My traps caught only 1 more Ako longi and 1 more Auliscomys (in the forest, but a place with lots of Berberis percei and some currant. Adrian caught 4 longipilis, an Oryzomys (in the clearing), and a big Chelemys. Many fewer mice than last year at this season. Back to Bariloche at noon. May 4. Wennt out to INTA to see Bellati, but nobody there. Valverde came to remind me about my speech on Friday. Morning was cold, about -2, and clear, then clouded up. Drove to Llao Llao to the bamboo area; some horses grazing there. Then drove to the place between the hippodromo and the Centro Atomico, where Anita and I trapped last year. Put 36 Shermans through the nire scrub, with scattered retamo, radial, neneo, acaema, and mats of compositae ground cover. Also put 30 Shermans up the hill through scrubby, cut cipres/radial/rosa. Put out the traps 5 to 6 pm; by 7 pm had one longipilis in the dozen traps that I checked near camp. No wind. May 5. Night clear, calm, heavy frost on the nire steppe. Evening and before dawn I heard an owl in the woods giving a eeeeya call every 20 seconds or so. Also heard barn owl once. The traplines produced in total 4 Ako longipilis, 3 Ako olivaceus, and 13 Oryzomys. The oryzomys were in both lines. Back to Bariloche at noon. Processed mice. May 5. Bariloche. Conference with Adrian and Christie. Dinner with Patricia and Jorge Vallerini. He is happy with the high wool prices. May 6. Bariloche. Gave lecture at the University: "The black hole of the Cuyin Manzano: a study in biogeography." Rapoport, Chehebar, Grigera, etc. were

there. Chehebar says that in drainages that have the big crustaceans, the mink eat lots of them; in other drainages they eat mice. Adrian identified some of the mice as Irenomys. Grigera and coauthors has just published "Flora of Puerto Blest." May 7. Bariloche to Buenos Aires with a dozen live Akodon longipilis for Martha Piantanida. She was supposed to meet me at the airport but didn't show. Turns out, I had given her the wrong date of my arrival. Ho hum. May 8. Buenos Aires. Went to the flea market in San Thelmo and found some good old postcards of Llao Llao, Valle Encantado, etc. May 9. Went to the Facultad de Medicina in the morning and talked with Kravetz, He is not going to the mammal meetings in South Carolina, but still wants to invite the Society to Argentina. Also talked with Maria Isabel Belloqc about her owl predation thesis, and with a new student, David ... , who is doing diet studies of the mice in Kravetz's agricultural/border study area. Gustavo Zuleta was there also. In the afternoon went out to the Natuiral History Museum where the mammal department consists of Martha Piantanida and Abel Fornes's widow (technician). They had some akodons that they wanted me to identify, and we pawed through assorted Buneomys (=Auliscomys micropus) and Phyllotis. They, dressed in their white lab coats with overcoats over them, hunted down skulls (not always successfully) while I peered through the gloom of a distant light bulb at the specimens. There was an interesting series of six Phyllotines from Las Cuevas, Catamarca, that were uniformly pale golden, small feet, phyllotis-like interorbital, throat and belly not Graomys, the teeth somewhat strange: maybe Andalgalomy s. Two much larger beasts from thje same place but greyer, not golden. Also found a Phyllotis osilae from Cordoba Province, and maybe some others; they are going to hunt down the skulls. In the preparator's lab were three jars containing two Buneomys (labels say) from Somuncura and maybe Rio Pichilefu, and the other with a big Notiomys. These presumably were from Bonino, Bellati, and Susan Martin and had been sent to Crespo, who is alive but in poor health. The specimens in the University collection that I contributed to in 1964?) and that Martha curated were pretty much destroyed by rats; the remains were sent to the Mar del Plata museum (Scaglia). Bone chill drove me home at 6. May 10. Buenos Aires. Went to La Plata on the bus. Alcover was not there but was warmly welcomed by Dra.... Brandoni ..., who is interested in fossil Octodontidae, another lady whose husband?? works with sharks, by Diego Verzi, the student who is working with Alcover on Aconaemys, by Richard Madden a yankee from Duke who is working on fossil primates from the La Venta fauna, and his Chilean lady assistant. Pascual was not in but was due to attend a PhD presentation on fossil sharks in the afternoon. The wonderful macro-fossils are still on exhibit but poorly lit, dirty glass, haphazard labelling, and chilly ambiente. There seemed to be much more student activity than at the museum in BA. The mylodon skin and droppings

have been moved; a young man who helped with the Cueva Traful identification of larger mammals opened the case and let me fondle the Mylodon fur. Alcover and Diego had been to Hui Hui, Laguna Verde, Lago Currhue, Lago Norquino, etc. and had caught both Aconaemys and Octodon. I did not see the Octodons, but saw about 10 flat skins of Aconaemys and maybe five skulls, plus some skulls that they had borrowed from the museum in Valdivia. They seem to be convinced that there are two tooth patterns that would correspond to fuscus and sagei. They had specimens of sagei from Hui Hui. May 11. Buenos Aires. Went out to the Museum again. Had a tearful session with Martha Emilia de Fornes as she reminisced about Abel and how people took advantage of him. Some of his personal collection ended up in the Museum and is kept as a unit in two separate cabinets, one for bats and one for the mice. It is in better shape than the main collection, but nonetheless I couldn't find several skulls that I wanted to see. Martha Piantanida showed me the enormous data bank that is her thesis on Akodon dolores- growth and reproduction in captivity. Just as I was leaving, Josep (Toni) Alcover and Diego Verzi arrived. They had been looking for me at the hotel and had been unable to reach the museum by telephone. We went back to the hotel where they photographed my specimens of Aconaemys, and then we talked about Octodon and Aconaemys. They have prepared a manuscript on the first occurrence of Octodon bridgesii in Argentina, with specimens from Lago Currhue chico and from along the trail that goes from Laguna Verde to Volcan Huanquihue. The latter was on the way up to the Escorial where we caught our specimens. They were in bamboo habitat, and Aconaemys lived nearby. In fact, I think they said that they caught Aconaemys and Octodon from the same burrow; if not, very close together. Rattus norvegicus also nearby. They also caught Irenomys and six Dromiciops. They seem happy with calling their specimens Octodon bridgesii, based on the drawing in Osgood and with comparison with two specimens borrowed from Valdivia. All of the Octodon were caught with rat traps baited with "pan con aceite." May 12. Buenos Aires. To Facultad de Medicina again, where I talked with Kravetz, Bellocq, and Maria Busch. Kravetz is finding seasonal differences in the immune systems of mice (Akodon azarae I think). He cannot say yet whether it is connected with population density. Dinner with Gustavo Zuleta, who is promoting a new but still non-existent journal of Argentine ecology. Carlos Verona would be the editor. The Argentine ecological society does not seem ready to act, nor CONICCT. Two years ago I offered to supply a desk-top-publishing computer, but still just talk.

Pearson-1988 7 Akodon longipilis April 16. Michael Christie brought in two skins from Copahue, 1650m. April 19. 47 big Shermans overnight at Arroyo Carbon caught 10 Ako longi and 19 Oryzomys, none juvenal. Every rosa mosqueta buch had a pile of eaten fruits under it; the seeds nibbled open (= Oryzomys). Saved ?

The skip from #88-04-3 to 20 was a goof; it includes 7 live captives to go to Martha Piantanida. April 23. La Veranada. 38 Shermans overnight caught 10 Ako longi. Killed all of them and saved skulls. Haven't located the data file yet. 5 males and 5 females; two of the males had 5 to 6mm flabby testes, flesh colored, conspicuous artery, and very long penis, something like 4mm wide, and with a long baculum ?10mm? Two of the females had scars. One female had a quite wide vagina, but not particularly muscular. Distance from anus to genital papilla was consistently something like 13 to 15 for males and 8 to 10 for females. Three of Bob Timm's parasites recovered from the killing bucket in which they were the only species. 88-04-25 f 88-04-26 f 88-04-27or29 f (two skulls labelled 27 and no 29) 88-04-28 f 88-04-29or27 f 88-04-30 m 88-04-31 m 88-04-32 m

Saved two skins and one in formalin. When handled they squeezed, unlike Akodon longipilis, which were silent and more tranquil. Same lines caught 4 longipilis and scads of Oryzomys. I lost track of which traps held the olivaceus.

Ctenomys sociabilis April 19. Arroyo Carbon below La Lipela. Saw no fresh diggings at the usual place 10km N Nahuel Huapi; ditto at 20km N near the new trout farm, and 30 km N at the Arroyo Carbon place. Talked with the puestero on Estancia La Lipela while I was camped at Arroyo Carbon. When asked about small mammals he pointed to the west (Cuyin Manzano) and said there were ratas de la sierra there. When asked about tucos, he said that there were none here but lots across the Limay River. He said the tucos make a sound like their name, the rata de la sierra makes a more squeaky sound, which he imitated; says they live in burrows like tucos. i.e. He distinguishes sociabilis from mendocinus!

This female gave birth to the live captive Yanez et al in the Hershkovitz volume give chinchilloides from Tierra del Fuego and adjacent mainland TL 186-237, tail 59-83, HF 25.4-32, GL 29.6- 34.8,TR(alv) 5.6-6.2, diastema 7.4-9.0. For noei from Santiago they give TL 200-268, Tail 61-88, HF 24-32, GL 29.6-35.1, TR(alv) 5.0-6.3, diastema 6.8-9.5. So these monsters are only slightly larger than many of the existing specimens from elsewhere. They are much larger than any we have seen among the ?15? or so specimens from around here. In thinking about two species of Buneomys of different sizes, don't forget my toothrow measurements from hundreds of Cueva Traful specimens; the length of toothrow was spectacularly bi-moda, with the smaller one much more abundant. April 20. The young live one that Michael brought in, born in captivity to #652, has not eaten endive, rosa mosqueta fruits, or nuts of Araucaria. It is very inactive. I have been feeding it apple, rolled oats, and Dogui dry dog food. May 2. The captive eats small amounts of fresh clover leaves, grass, and dandelion leaves. Today it weighed 30 g. It was born in captivity, the mother was MIC 813, and a litter mate that died weighed 3 g on Feb 1, so the birth date must have been about Jan. 30 or 31. (Note discrepancy on who was the mother). Anyhow, this captive has not grown appreciably in the two weeks I have kept it, and it is probably 3 months old. In reviewing the literature, it seems that there must be at least two species of Buneomys in Argentina, mordax, a big one, and petersoni a small one. Chinchilloides from Tierra del Fuego is a big one and may come up along the Andes to Santiago and cross over to meet mordax. So mordax might be a synonym of chinchilloides. Two species or three?

36 Journal October 19- Arrived Bariloche about 5 p.m. by plane from Buenos Aires. Seemed to be a big dust storm over Chocon area. Steppe looked wintery; lots of snow on hills around Bariloche, some of it last night, but none on the steppe. October 20- Bariloche. Cool and mostly cloudy. Shopped and got car started. Pear trees in bloom in town, some tulips, some Scotch broom. Saw Marcelo Betinelli, Patricia Fierro, Chehebar (who has released one otter with radio transmitter at Isla Victoria but has not been able to locate it), and Adrian Monjeau (who went collecting with Dickerman from Wisconsin between here and the coast). They stopped at a cliff along the road near the town of Clemente Onelli acnd found a freshly dead Lestodelphys at the base of the cliff. Also lots of owl pellets. They set traps south of Los Menucos at a place that sounds like our Lesto locality and caught lots of Eligmodontia, an Akodon iniscatus, and ... This was about a month ago when populations should have been low. According to Patricia, the autumn was warm and spring-like, but considerable snow late in the winter. Lots of snow on the mountains now. October 21- Bariloche. Cold and rainy all day; did chores around town and around the apartment. Michael Christie visited. October 22- Bariloche. Cold, mostly cloudy. After lunch drove to Llao Llao Peninsula and stopped in the Coihue and cana forest on the shore of Lake Perito Moreno (west branch), 24 km WNW Bariloche. No blooms yet on the Scotch Broom at Llao Llao, and the Berberis darwinii is not blooming yet although a few buds about to burst. Quintral blooming and Anita saw two hummingbirds. At 3 pm I set out 35 Shermans and 25 Museum Specials in dense bamboo/Coihue/icpres forest. Big overmature trees. Anita set 32 Shermans and 11 Museum Specials, plus 2 steel traps. Checked my traps at 6 p.m. and had one Chucao in a snap trap. Checked Anita's at 7:30 and had nothing. Oct 23- Lago Perito Moreno, 24 km WNW Bariloche. Night overcast, some sprinkles, then drizzle in morning. My line caught 1 Oryzomys and 8 Ako longipilis; 3 of the Ako longi in snap traps and two of them by the tail. Anita caught 5 Ako longi, two of them in the 2 steel traps, which had been set at places where there was sign of digging. One was at the mouth of a rat-like burrow. Back to Bariloche at 10. October 24- Bariloche. Visited the office of Fontinalis S.A. and saw Christie, Tarak, Patricia, and Cacho Carranza. In p.m. went up Cerro Otto and measured bamboo. Some patches of snow still on the southeast slope where our bamboo is. Leaf markings still visible on the bamboo.. October 25- Shipped three unnumbered male Ako longi and one female (# ) to Martha Piantanida via Austral. Conference with Monjeau. Then to La Veranada. Temp cool, mostly cloudy. The road still being worked on, not

This locality is 43 km SSW Bariloche, 1030 m. at 4 p.m. I put out 29 Shermans baited with rolled oats alternating with 29 Museum Specials baited with corn meal. All in bamboo/nire and bamboo/lenga along the woodcutters road on the west side foi the highway, south of our grid. Good rich ceover, patches of snow, 4 horses. Anita put out 26 Shermans and 18 MS near camp in nire/bamboo parkland. Then we located the two marked bamboo clumps. One of them had NO yearling canes. The other had a number of yearlings but most of them damaged at the tip. October 26- La Veranada. Night mostly clear, cold. Teapot in tent frioze, not solid. Heard tero-teros during the night and, incredibloy, frogs calling- with the temperature far below freezing. My 58 traps through nire/bamboo and lenga/bamboo forest caught only one mouse, an Ako longipilis. Anita's 44 traps in nire/canya,scrub parkland near camp caught one Auliscomys, 1 Oryzomys, and two Ako longi. Marked bamboo clump E3, the new one situated along the path behind where we used to camp (but noi longer accessible from the highway). That clump produced about 78 new shoots last spring and summer, but only three of them have survived to healthy yearling status. Most died as 6 to 8-inch shoots; some died as bigger shoots but with the tip dead, and some survived to more than 1 m tall but with the tip dead. Between two-thirds and three- quarters of the short shoots had been attacked by boring parasites, and many of the remainder may have been attacked also but I could no longer be sure of the evidence. Almost all of the taller shoots with dead tiups had been attacked by boring parasites. Wouldn't it be nice if heavily parasitized clumps could give off a pheromone that would alert neighboring clumps to an intolerable parasite load, and that this could lead to mass flowering? Afternoon clouded over, but warmer. I picked up half my line in tyhe woods and put it in bamboo/bushy parkland near our old campsite, plus a dozen traps out in bamboo/bush islands out in the open meadow. October 27- La Veranada. Night much warmer, partly overcast. Heard frogs and tero-teros again. My remaining half trap line in the woods had nothing, and the line in islands of bamboo in the meadow had nothing. The new line in brushy places near our old campsite had 1 Auliscomys and 3 Ako longi. Anita's line had 1 big Auliscomys. Total traps out about 104. Lots of hare droppings but we don't see hares-but haven't been night hunting. Horses, but no sheep or cows. Nire leaves not out yet, a couple of dandelions. Something nips off terminal twigs of sapling sized nire (but not old nire). Sometimes 6 feet high in the middle of a clump, so not horses or hares standing on snowcover. Maybe Auliscomys? The biggest cut twig was

Pearson - 1988 38 about 1/2 inch, but most smaller than a pencil. A few had been partly "barked". We found only the stubs, not the terminal parts which presumably drop to the ground. Took some fresh twigs home to test on captive Auliscomys and captive Ako longi. One 1-inch terminal shoot that we cut into had a hollow and a "nest" of striped ants with larvae. The hollow place probably had been made by beetle? larvae. Indeed, tthe nires, big and small, are riddled with galleries up to a half-inch in diameter. October 28- Bariloche. Cold, rainy, snowy all day. Conference with Monjeau, then dinner with Patricia Fierro and Jorge Vallerini. Neither Ako longi nor Aulicomys touched the nire branches in their cages. October 29- Bariloche. Cold and clear; touches of snow on the ground in the back yard, and roofs covered. Michael Christie came by, said that this past winter had been unusually cold with more than the usual number of pipes freezing, but not as severe as 1984 the year of the big snows. He also reported that Conrad Bailey says that the weather records at Estancia San Ramon indicate considerably drier than average years for the past three years. At 6pm put out traps across the road (south) of the aeroclub flying field 11 km NE of town. Habitat is a rich mixture of bushes, especially rosa mosqueta and Colletia, but also Berberis Baccharis, neneo, and many others. Many dried rosa mosqueta fruits still hanging on the branches, and numerous rosa clumps with seed caches under them. Weather cold, overcast. Anita put out 19 Museum Specials and 23 Shermans. I put out 31 of each, alternating. October 30- Bariloche. Morning cool, overcast. Anita's snap traps had 2 Oryzomys, 1 Akodon xanthorhinus, and 1 Auliscomys. Her live traps had 4 Oryzomys and 1 Auliscosmys. My snap traps had 7 Oryzomys, 2 Ako longi, and 1 Auliscomys. My live traps had 2 Auliscomys, 5 Oryzomys, 2 Ako longi, and 1 Reithrodon. Total 114 traps, 29 mice. October 31- Morning clear, cool. Javier Bellati visited, with fox data from Pilcaniyeu and from Estancia Condor. Trappers at both places say that they catch 20-30 foxes per year, only grey foxes at Pilca and only red foxes at Condor. He and Julietta have many years of data of percent of bait stations visited by foxes, hares, mice, birds, lizards, insects, skunks, and hurones. Hurones only at El Condor, not at Pilca. The frequency off fox visits follows the frequency of hare visits by one year. Commercial hare hunters worked the road between here and Los Menucos last winter. At El Condor they were taking 100 to 200 per night (jacklighting with .22 rifle). Arturo Kolliker is no longer at Estancia San Ramon; his replacement is Billie Doll, married to the girl from Fundacion Bariloche who was studying lenga. Julieta is at Colorado State learning telemetry. At 6:30 put traps on the lower slope of Cerro Otto, just a little past the last house (vivero). Habitat brushy: cipres, maiten, notro, Mutisia,

Pearson - 1988 39 radal, rosa mosqueta, a small amount of Colletia, spiny-edged bromeliad, not much grass. I put 22 Museum Specials and 22 Shermans; Anita put 19 MS and 21 Shermans. This was on the way back from another visit to our bamboo clumps farther up on Cerro Otto, where we counted marked leaves and marked some new ones. Still patches of snow near the bamboo clumps. Overcast. November 1- Bariloche. Morning clear, not cold. Ran traps at 7am. The 84 traps had 1 Oryzomys (discarded) and 2 Ako longi (Anita's line) and 1 Auliscomys and 2 Ako longi on my line. The altitude was 1000 m. November 2- Left at 10:30 for Rio Castano Overo. Mostly overcast. Picked up Genarmeria Silva to Pampa Linda. He says gendarms man the station all winter; sometimes they have to go to Hotel Mascardi by horseback. Some tour groups come at any time of winter if the road is open. The Berberis darwinii was in full bloom along Mascardi. Worked on bamboo clump F2. Two very small clumps along the road were blooming, about 2 m apart so they might be the same clump; they were heavily grazed, and the yearling culms were sending out blooms. Then set traps. My line was almost all along logs: 28 MS and 36 Shermans, mostly set in pairs. Anita put 27 MS and 27 Shermans near camp. Camp is along the road a half-km short of the big camping place., We stopped there because the road was near-impassable. Two men and 5 horses went by returning from packing some climbers in. The mallin is wintery, but the nires beginning to leaf out. November 3- Rio Castano Overo. Night was clear, mild. Anit's traps had 1 Ako longipilis and 2 Akodon olivaceus. These two look different from eachother; check skins and skulls. This locality is close to the type locality of mansoensis. My trap line had 5 Akodon longipilis (3 in snap traps and 2 in Shermans). Worked on the bamboo clump in the forest and moved about 10 of my traps. One of the big orange bumble bees visited the orange blossoms on Berberis linearifolia near camp. It knocked off petals as it climbed around the blossoms. Sunny and warm all day. November 4- Rio Castano Overo. Night clear, cool, no frost. Anita's traps nothing. My traps with 1 Chucaco, 1 Liolaemus, 1 Oryzomys (dead), and 5 Ako longipilis (2 dead. Processed mice, took photos of bamboo and scenery, counted leaves on bamboo. Stopped at the new confiteria at Pampa Linda on the way out. It is run by Roberto Chihuay who remembers a bamboo bloom about 1946 at Llao Llao; lots of tiny mice. He recommends talking with his uncle Juan Chihuay who lives in the 700 block of Blordi. Day sunny and clear all day. Stopped on the way home to photo Berberis and saw a giant orange bumble bee feeding on Berberis darwinii. Berberis linearifolia was blooming in the same clump. Darwinii is not available at Castano Overo where I saw feeding yesterday on linearifolia. Home 7:30 pm. Marcello Bettinelli and wife called at 9:30 to return film

Pearson - 1988 40 20 that they had "rescued" when the refrigerator broke down. Also stopped to talk with Sigfriedo Rubulis. He says the winter was cold, not much snow, so the ground froze deeper than usual. I could not pin him down to any definite statements about glaciers on the Cuyin Manzano. He thinks Flint and Fidalgo's statements about number of glaciers, extent, etc., are based on slight evidence and probably not true. Sigriedo does not think rounding of hilltops is a good indicator of how deep the glaciers were. He also points out that there must have been minor glaciers coming down the side valleys to complicate the picture. November 5- Bariloche. Did laparotomies on captive Akodon and built cages. Weather mostly sunny. November 6- Bariloche. Rain overnight, morning clear and windy. Had a brief visit with Albert Franzmann and wife Donna, big game expert from Alaska. Chehebar, Eduardo Ramillo, and Michael had been showing him around, and he was about to leave for Tierra del Fuego, later to work with Roig in Mendoza. Worked with longipilis data, then in afternoon counted bamboo leaves at one of our marked clumps on Cerro Otto. Snow gone. Then set traps in the bamboo/lenga/grass, especially along the edge of swath that had been cleared about 2 years ago for a ski trail. Cut bamboo and logs had been pushed in windrows along the mqrgins; good cover. I set 32 Sher mans and 20 Museum Specials. Anita set 29 Sher mans and 27 Museum Specials. Cool, windy, scattered clouds. November 7- Bariloche. Morning cool, clear. Ran traps on Cerro Otto. This trapping site is below Piedras Blancas on the east slope. My traps had 3 live Ako longi and 1 dead, 1 live and 1 dead Aulisc omys, and 1 Akodon olivaceus. Anita's had 3 live Ako longi, 4 dead Ako longi, and 1 dead Akodon olivaceus. These olivaceus are small and xanthorhinus-like, similar to the ones from the Hipodromo west of Bariloche. The 107 traps held 14 mice. Chehebar came to talk about his otter and mink data. The otters are eating almost entirely crustaceans, only a small amount of fish. He doesn't find otters in those drainages without the crustaceans. The mink eat mostly crustaceans also, but also mice, birds, fish; no coy pu. Michael Christie came by. With Franzmann he had seen guanacos along the east side of the Limay below Nahuel Huapi.. He told of a paper by ?Noria? on speciation of Sporophila. Apparently, in the pampa area in the past, a modest rise of sea level created ?three? long, east-west peninsulas that provided suitable habitat for Sporophila, and cut off from each other by forests to the west. This might explain tuco-tuco distribution? The north-south sand ridges on the pampas, coupled with these peninsulas, would explain a lot of chaotic tuco speciation. ?Noria? also claimed that everything on the Chilean side of the mountains south of Puerto Mont was wiped out by glaciers down to the sea. Maybe Chiloe was a Pleistocene nunatak where Dromiciops, Irenomys, Akodon

Pearson - 1988 sanborni, Rhyncholestes, etc. survived? November 9- Lago Escondido, 24 km WNW Bariloche. In the afternoon drove out to the Llao Llao peninsula and counted bamboo shoots at our marked clumps, then camped at the picnic area at Lago Escondido and put out traps. Anita put 29 Shermans and 29 MS, and I put 30 Shermans and 30 MS; all in pretty pure bamboo with scattered huge coihues and cipresses. Not many logs. November 10- Bariloche. Night calm, clear, mild. Saw one bat flying in the forest at dusk but not out over the lake. Anita's traps had 4 live and 2 death Ako longi; my traps had 13 live Ako longi, 1 dead Ako longi, and 1 death Oryzomys. These lines for the first time showed a clear superiority of the live traps (all the dead ones were in snap traps). My Oryzomys was under the big rosa mosqueta in the open clearing where I had shown Isabel the rosa fruits eaten by Oryzomys. Several of the Ako longis were in pure dense bamboo, such as in the "tunnel of love". All day processing mice. November 11- Bariloche. Cloudy, then clear, windy. Mice and bamboo in apartment. Anita went to Maddie's for tea, the "English" gardener lady who lives 2 blocks farther up our street. The cold last winter killed back her young, bushy arayan tree and her native fuchsia bushes. To the Ninos y Jovenes Cantores in the evening. November 12- Bariloche. Partly cloudy and very windy. To Christie's for tea with Richard Klug and wife Clara. He is a retired forester with a Master's from Berkeley in the 1930s, ran a saw mill here in Bariloche until a few years ago. He says Lenga is OK for windows, trim, furniture, etc., coihue not as good. Deplored how many of the big trees were hollow "from fungi". November 13- Bariloche. To our bamboo on Cerro Otto. Sunny. Killed mice and measured bamboo in the apartment. Michael Christie came by with Buneomys publications. The Princeton illustration of Buneomys petersoni definitely has laterally placed grooves on the upper incisors. Os good's illustration of FM 50736 also shows laterally placed grooves. November 14- To our marked bamboo clumps on the Llao Llao Peninsula where we counted marked leaves. One culm had been vandalized, and one had died. Then set traps . Went back the first road into the forest after passing the Villa Tacul road. The road branches; the right branch goes back to an open meadow area with the native retamo etc and had recently been "reforested" with cipresses and ?radal? about a meter tall. Many of them death or dying. Two caranchos there at dusk. The left branch crosses a stone bridge, goes through dense bamboo plus enormous cipresses and coihues, then begins to open up, but I didn't follow it all the way. I rather suspect that the Llao Llao hotel once had a farm and stable back here. I shall refer to it as Llao Llao Farm. Didn't see any old buildings. We walked through the meadow area at dusk when there should have been hares all about, but we saw none. In fact, no droppings either, and I don't recall ever seeing hares on the Llao Llao peninsula. Anita set 27 Shermans and 34 Museum Specials back the right branch of

I set along the left fork, all in bamboo etc. At dusk saw 1 Tadarida? and one or more Myotis. Heard barking owl (=Strix?). Night calm, not cold. November 15- Llao Llao Farm. Morning calm, mostly clear. nita's traps had 2 death Oryzomys, 3live and 3 dead Ako longipilis. My traps had 3 Oryzomys alive (released), 5 Ako longi in Shermans and 4 in snap traps. Back to Bariloche for processing. November 16- Started off to set traps along the back road to Catedral, from Lago Gutierrez, but got sidetracked to a nice bit of forest at the end of the roadalong the west shore of Lake Gutierrez. The road ends at a Park Campground which is remarkably open coihue and sparse bamboo forest, medium-sized trees. Locked the keys in the van, so never did get around to setting traps (removed window to get in, then had to get a pro to re- install the window). November 17- Drove to La Veranada to measure light intensity around bamboo, but the nire leaves still are only partly out. The Berberis darwini along Mascardi is finished, the Scotch broom full out. November 18- Talked with Juan Chihuay, Elordi 659, born 1918. His nephew runs a Hosteria at Pampa Linda. Juan remembers a flowering of the bamboo on the Llao Llao peninsula in 1939, followed the next year by an outbreak of rodents smaller than rats, with medium-long tails. See bamboo species account. The park banished cattle from the Peninsula in 1936. He didn't seem to think that the Hotel had a dairy farm there. He says there was a rosa mosqueta bush at the Jones place at Nahuel Huapi in 1908. Drove to Lago Escondido in the afternoon and set out traps along the trails through the bamboo/coihue/cipres forest. This time we started from the west end of the lake near a giant dead cipres. Anita put 32 Shermans and 32 Museum specials, and I put 27 Shermans and 30 Museum Specials. Took photos of bamboo. Started to Scotch mist at dusk. November 19- Lago Escondido. Misty drizzle much of night but not cold. My traps had 4 live Ako longi, 1 dead Oryzomys, and 1 live Oryzomys (released). Anita's had 3 dead Ako longi, 6 live Ako longi, 1 dead Oryzomys, and 1 dead Ako olivaceus, which was caught at the edge of a grassy clearing. Dinner with Gallopins. November 20- Bariloche. Cool windy. Tea with Dick and Clara Klugh. He has many kinds of trees planted around his place at the beginning of the Faldeo. He says the Coihues and lenguas grow very slowly, and he pushes for pines and firs (he has a Master's from Forestry at Berkeley in 1936 approx). November 21- Left 10:30 for Puerto Blest. Lunches along the trail near the bottom of the steps at Los Cantaros; lovely piece of forest with giant coihues and podocarps. Found numerous new clumps of bamboo there, frequently close to an old dead clump. See bamboo species account.

Pearson - 1988 43-25 Rosendo Fraga was the only other guest registered at the hotel. Had dinner with him. He is studying the food of hummingbirds here, mostly by netting birds and taking pollen samples on their feathers with sticky tape. He didn't catch any hummers today, and there are not may around. The fuchsias are not yet blooming, their winter food (the mistletoe ...) is finished blooming aaround the Llao Llao area and is said to not be here at Blest, and the Notro is just beginning but not very abundant here at Blest. Their food at the moment seems to be the vine Campsidium, and it is not very abundant. See Campsidium species account. We measured bamboo at our original clump. Production very poor; I believe every new shoot was parasitized. Most interesting was our discovery of numerous young clumps growing near our marked clump on the grid. see species account. November 22- Puerto Blest. Morning cloudless, warm. Measured our second clump of bamboo; production very poor. Then did our census of flowering clumps between the meadow and El Abuelo: 7 on the West side of the road and 11 on the East (river) side, total 18. Visited with Park Guard Pedro Pietro and wife, then home on the 5:45 boat. There is more alerces gtrrowing along the boat route than I had remembered. November 24- Lunch with Fraga. He still can't say how many, if any, of the Campsidium blossoms up in the trees are nibbled. He says the hummers do use Ourizia. November 25- To Cerro Bayo. The road to Villa Angostura is still unpaved except for about the first 5 km; but some progress. Drove up to the bottom of the ski lifts at Cerro Bayo on a fairly good cinder road, then zig-zagged about half way up the ski lift on a cinder road. The ski run was cut of virgin forest, maybe 100m wide, straight up and down the hill, which is cinders covered with long green grass. Up near the top it becomes rocky with alpine and ericaceous plants; a couple of dwarfed lengas at the ridge line, where it was cold and windy. At the bottom of the ski run the forest is coihue. Where we camped, which I estimate to be 1300 m, there was a mixture of big coihue and big lenga; most of the big ones were coihues and the younger ones were lengas. The understory was bamboo, current, Drimys, and 3 or more species of Berberis. A few bamboos were blooming. Higher up, the forest was lenga, but there was no clear zone of lenga achaparrada. The bamboo stopped about 100 to 150 m altitude above our campsite. The huge trunks that had been cut to make the run had been pushed to the edge of the run and seemed to be perfect habitat for Akodon longipilis and Chelemys. Much of the bamboo had been heavily grazed, and there were cows grazing on the ski run. In some places I noticed that short bamboo only a foot or two tall was ungrazed, suggesting that much of the grazing is in winter. I was surprised to find sympatric skiing and coihue. How come if there is enough snow for skiing it doesn't break the limbs of the non-deciduous coihue? We hiked up to the top of the lifts (one of the two is new and not

finished yet) looking for mountain meadow or mallin habitat suitable for Buneomys mordax, but there was none in sight. Considerable "bald" area suitable for the small Buneomys, but we saw no droppings of any sort (except hare) and no sign of mice of any kind. There were not many hideholes, but enough so that Buneomys could live there. To the north and east one could see other balds of the Cullin Manzano peninsula sticking up above a band of lenga. In a couple of places the sharp lower limit of the lenga was immediately above open slopes littered with big dead logs, suggesting fire. No sign of roads or habitations anywhere. Two herefords wandering on one of the balds! I put 22 Shermans, 18 Museum Specials, and 2 steek traps among logs, currant, Berberis, and bamboo at the edge of the grassy ski run. The upper end of my line was at the upper limit of the bamboo. Anita put 28 Shermans, 28 Museum Specials, and 2 steel traps around camp in the mixed forest. One deep gulley near camp had a steep moist slope maybe 50 ft. high covered with blooming Ourizia. The Berberis is in full bloom also. November 26- Cerro Bayo. A touch of frost out in the open. My traps had 1 live and 1 dead Akodon longipilis. Anita's had 2 dead Ako longi. One steel trap had been molested by a fox. Then back to Bariloche and dinner with Patricia Fierro and Jorge Vallerini. He said that he didn't know of any coihue above about 1200m. November 27- Clear and warm. Went out to Estacion Perito Moreno with Fraga. The lake, Laguna de los Juncos is completely dry. We walked all the way across it; the tules are all collapsed and dried up. Then I hunted for about a half hour on our Reithrodon meadow on Estancia La Fragua, looking for Reithro sign. Found only one small group of droppings, no other active holes. Lots of hare droppings, plus sheep droppings. The gropund seemed very dry, but lots of growing thistles etc. in the railroad right-of-way.. Then we hiked up to the ridge below the condor cliff. At a green liloradero on the way up I saw one oucher group of Reithrodon droppings. One or two condors soaring high above the cliff. No guanacos or red deer there, but saw guanaco droppings and guanacos on the skyline on the way home. November 28- Bariloche. Sunny and warm. November 29- Bariloche. Went to Fraga seminar at the University. He and student Alejandra seem to have found pollen of Ourizia, quintral, and Campsidium on the hummingbirds. They assume that they use quintral during the winter. There are no hummers at Puerto Blest in the winter, and no quintral. He says nectar of Notro is too thick for them and has not seem them visiting notro. Then put out traps at Llao Llao at Lago Bscondido, almost same lines as the last time there. Weather calm, warm. The Scotch broom at Llao Llao in full bloom. I put 30 Shermans and 30 Museum Specials; Aita put 28 Shermans and 27 MS. November 30- Lago Bscondido. My line caught 2 Oryzomys (1 of them in MS), 2 Ako longi alive, and 1 Geoxus alive. Anit's line caught 3 dead Ako longi, 2

Pearson - 1988 45_25 live Ako longi, 1 live Geoxus, and 1 dead Oryzomys. Returned to Bariloche and processed mice. Day sunny and calm. December 1- The captive female Geoxus ate 10g of Oryzomys carcass in 20 hrs. The male, after having mouse carcass but no water overnight, drank immediately when offered water. Drove up Cerro Otto with Fraga and marked still more leaves. Sunny, warm, and calm. Photos 4x5 of the two marked clumps of bamboo. December 2- Bariloche. Clear, sunny, calm. Drove up Cerro Lopez with Anita and Fraga to the end of the road (a few snowdrifts), then hiked up to the Refugio at 1600m, where there was lots of snow. The awful road goes through dombeyi, a few nires, then lenga. Bamboo goes fairly high but not to the lenga achaparrada. Found no Buneomys or other droppings up in the rocky-snow near the refugio; one jaw of an Akodon longipilis. Set 5 Shermans in lenga achaparada on our way in, then picked them up 5 hrs later, nothing. The captive Geoxus each ate 17 g of mouse carcass in 24 hrs. December 3- Bariloche. Sunny, warm. Christie came late last night with comments on Buneomys ms. He quotes Conrad Bailey of San Ramon as saying that the current drought is becoming serious and that animals are dying in some parts of the Province. The captive male Geoxus ate 19g of Akodon longi carcass, and the female ate 12 g or Oryzomys carcass (all there was except some skin). They eat the smaller bones such as ribs but leave veretebrae and pelvis. December 4- Bariloche. Morning mostly cloudy, not cold. Geoxus ate lamb and beef, a little apple. Found a wild bamboo plant along a stream on the next road west of the University (towards the pine forest). Started measuring growth of leaves and interleaf distances on the bamboo plant in the front yard next door to our apartment. December 5- Bariloche. Went to the big cave at Cerro Leones with Patricia Fierro and Rosendo Fraga. There is a hummingbird nest (Oreotrochilus) well inside the cave, quite dark, about 12 feet up. The female? was incubating. She flew off when we approached, but returned several times during a half- hour while Patricia was taking flash photos. No young visible. The only "hummingbird flowers" seen nearby were a couple of bloomingh Notro 150m away and a big patch of Notro about a half-mile away. We picked up about a gallon of owl pellets at the usual spots along the cliff, but didn't make a very complete collection. The captive female Geoxus gave birth to 4 young. December 6- To Lago Perito Moreno on the Llao Llao Peninsula in the afternoon. Day mostly cloudy, some drizzle at Lago Moreno while we set traps in bamboo/coihue/cipres forest along the road back to the campsites. Anita put 21 Sher mans and 21 Museum Specials and I put 21 Sher mans and 24 MS. We also put some traps along a side road, the first one to the right after passing the Fundacion Bariloche center: Anita 7 traps and I 4. Almost all of the access roads have now been ditched or posts planted

Pearson - 1988 46 28 so that you cannot drive in. The bamboo in the tongue of forest that the road goes around seems to consist of young clumps. The Scotch broom at the Llao Llao is full bloom. Anita saw a hummingbird at our campsite oin the edge of the lake. December 7- Llao Llao. Drizzle stopped about 10 oclock, then mostly clear. A pack of 2 or 3 large dogs visited camp. Anita's traps had 4 live Ako longi, 1 dead Ako longi, and 1 dead Auliscomys on the line near camp, plus 2 live ones and 1 dead one at her other line. My line had 4 live Ako longi, 3 dead Ako longi, and 1 dead Auliscomys. While we were picking up the auxiliary trap line, a pack of 3 large dogs came through where we had parked, seemingly hunting silently. A hare had passed through just as we arrived. One clump of bamboo at our campsite was in full flower with stamens hanging out. A caged Akodon longipilis removed some oof the flowers from a stalk and left some stamens lying around. December 8- Discussion of his thesis with Adrian Monnjeau. Milton Gallardo arrived from Valdivia in the evening. December 9- Milton brought a manuscript from Reise: A revision of the genus Buneomys. Reise thinks that mordax should be a separate species, but does not recognize sympatry. He has specimens from Pino Hachado, and Milton says that there are two karyotypes, 2n= 56? and 58?, but I am not sure from what localities. Also a manuscript on chromosome evolution in Ctenomys (by Gallardo), and another by Gallardo and his student on Oryzomys longicaudatus. He thinks that on the basis of size, penis morphology, and karyotype there is a break at about 50* latitude, with the souther form being a full species magellanicus that lives on both the mainland and at least part of Tierra del Fuego. December 10- Up to Cerro Catedral with Gallardo, but the lifts were not operating (they don't run on weekends). Saw no blooming bamboo on a quick survey down the back road to Lago Gutierrez. Fraga came for dinner. He says a ?robber? fly systematically visits Notro blooms. Then to movies with Gallopins and Gallardo. December 11- Gallardo left for Valdivia on the bus. To an asado in the afternoon at David Pruden's on Lago Moreno. His bamboo is as luxurious as ever: dense clumpns, abundant lush leaves, quantities of tall, thick new shoots. Conrad and Julie Bailey were there from Estancia San Ramon, say the spring has been excessively windy (and dry). Jacob, the owner, is going to fence off one or more areas for a nature preserve containing whatever happens to be inside the fence when it is put up. Drizzle in the afternoon and night. December 12- Bariloche. Patricia came by, and Nora with data for Buneomys specimens. At 5pm put traps out at the usual place beyond the Centro Atomico (12km W Bariloche, turn in from the lake at Puerto Perito Moreno for a couple of km), mostly in nire scrub with much open sandy areas with Acaena, radial, retamo.

There is some bamboo in a gully there and lots more along the road west towards Arroyo Casa de Piedra. The 4 babies born to Ako 7623 and abandoned weighed 11.6g. Looked at satellite photos of the Cuyin Manzano area in Monica Mermoz's office in Parques. She has one enlarged more than mine, and less contrasty, making it easier to distinguish types of vegetation. She thought it was taken in December of 1982, but from the amount of snow etc. it is more like April, and the date printed on it is early April. Maybe one-quarter of the area is steppe (almost all at the eastern edge), and two-thirds is forest or snow (maybe 1/8th snow). She distinguishes three grades of red as lenga, coihue, and cipres, and cannot detect bamboo. All the high-country forest seems to be lenga, but she didn't mention nire, which can be abundant fairly high up, as near Cerro Bayo. Approaching the Cuyin Manzano from Chile requires going through forest. She says there is a lot of grazing up above the town of Cuyin Manzano, and numerous people living up high in that region during the summer. She follows Flint and Fidalgo for distribution of the glaciers. December 14- Bariloche. Visits from Isobel Gallopin, Adrian Monjeau, and Juliana. Finished off the last Akodons. December 15- To Buenos Aires by air. The precordillera is still totally brown, winter-like; the pampa humeda with lots of standing water but said to be suffering from drought. Phoned Martha Piantanida but she said she had had no success breeding Akodon longipilis. December 16- Buenos Aires. Went out to the Ciudad Universitaria at Nunez to see Kravetz and Reig. The huge new building built in 1964 to escape from the miserable old buildings downtown looked like a disaster area: spray- painted political slogans on every wall, political posters everywhere, trash all over, dark hallways jammed with refrigerators and equipment, and no electricity at all because of the power shortage. 500 students standing in line waiting to enroll in courses. Huge banners draped inside the building's interior court by the student union, Franja Morada, urging the students to complain about things such as only passing 20% of the students enrolled in some course or other. Worst of all, a bust of Evita \peron in the main foyer with fresh flowers at its base. Because of the power outage, nobody was there until noontime, when the power came back on. Then talked with Kravetz about the future joint meeting with the American Society of Mammalogists. Roig will be going to the Alaska meeting. Then met with Reig and his group of students. They told about their various research projects, mostly chromosomes and some electrophoresis of tucos and Akodons. They have a paper in galley proof on Eligmodontia claiming 3 species: Peruvian, pampa-Patagonian, and Los Lagos in Neuquen, all three chromosomally quite different. They said that since submitting the paper they have gotten evidence that two of the species are sympatric near

Pearson - 1988 Pilcaniyeu. Also a paper on Reithrodon; a Brazilian-Uruguayan species, and an Argentine species. The power shortage is said to stem from lack of water in the Parana drainage. December 17 Buenos Aires. Second-hand book shopping with Fraga in the morning. One 2-volume travel book by an Englishman Scarlett on page 81 describes going to the Natuiral History Museum in Buenos Aires, seeing a stuffed crocodile, some ill-shaped fishes, all not being cared for and he opined not destined to last very long. Then he went to the legislature, which was in session. They were discussing a scheme to pay off the national dept "by borrowing the money!" This was about 1836. Tea with Helmut and Litzi Strohmeyer in their apartment. They have had some rain on their two estancias in San Luis and Media Luna in Mendoza, but considerable losses of cattle via fences burned in last year's fires and via rustling. She assumes rustling because the sex ratio of calves at the roundup was 700/500. The cattle loading chute is 12km from the ranchouse. Lots of plains viscachas and pumas. They gas viscachas by putting a moisture-sensitive vial down the burrow and cover it up. This kills the females and young. The males, she says, live elsewhere. The males come and open up some of the burrows, so mthey then gas those burrows again to get the males. Supper with the Franzmanns, whom we met on the sidewalkj by chance. They had been to Ushuaia. He, from Alaska, agrees that the Tierra del Fuego c climate is not all that bad and that the Fuegians don't want the rest of Argentina to know that they don't deserve their hardship pay. He say many mice running across the roads, not brown or yellowish, tail about as long as head and body. He was told not to bother going trout fishing because the trout were not biting because they were full of mice. They had been to Mendoza with Roig and to Parque Luro for field work with the red deer. The New Zealand deer man is starting asn operation near Luro. Franzmann had also been to Julio Contreras's house in Corrientes. Reig had been there and, according to Franzmann, told Julio that he should stop publishing "Historia Natural." Jan. 20, 1989 - Summary of trap success Oct-Dec 1988: 1592 trap nights, 183 animals = 11.49% 122 Ako longi, 35 Oryzomys, 16 Auliscomys, 6 Ako olivaceus, 2 Geoxus, 1 Ako xantho, 1 Reithrodon.

Akodon longipilis October 23- Lago Moreno. 101 traps last night in dense bamboo/coihue/cipres caught 1 Oryzomys and 12 Ako longi. 4 female Akos and 8 males. Three of the males saved alive to send to Piantanida and one kept for stud (7467). The two females dissected were large adults, vaginas open and muscular, ovaries with large pink follicles, not blister-clear so maybe they are early corpora lutea. Three other females, two of them with open vaginas, were kept alive for smears etc. 7466 F Adult, vagina open, caged with M 7467 7467 M adult caged with 7466 7468 F Adult, vagina open, caged alone 7469 F Adult, vagina not open but almost open (or recently closed), caged alone. October 25. Bariloche. Sent Martha Piantanida 3 unnumbered males from Llao Llao and one female (# ). November 3- Bariloche. The male caged with 7466 has wasted away and after several hours moribund but still warmish I killed him. Maybe the adult males die after breeding like Sminthopsis? Martha Piantanida's captive males died also. Massoia claimed that one never found longipilis with worn-out teeth. I have found a few, but maybe they were all females? November 7- The thought occurs that the excess corpora lutea might be derived from successive ovulations as in the mink. Those females today with beautiful pink corpora lutea that matched the number of embryos would be individuals that implanted promptly with additional ovulations. Therefore CL/fetus counts of the early pregnancies should match, whereas later pregnancies should have accumulated CL. The alternative explanation, that the excess CL are just left over from sterile cycles is negated by the previous finding of fertilized ova in the oviducts of many of such females. November 10- good sample from Llao Llao last night showed one late pregnant individual and the rest ovulated but not visibly pregnant; in fact, not advanced from our previous visit here.

Pearson - 1988 Bamboo November 14- At Llao Llao on the little side trail where Anita has some marked culms, we picked two long branchlets from one clump; one of them had 40 leaves and leaf scars, the other 42. At 2 leaves per year this makes 20 yrs; at 3 leaves per year it makes 14 years. One culm from which we had removed all the branchlets at one node had not replaced any of them. Another culm cut off at about 1 m was dying back from the top; two internodes were dry, but lower internodes still green. Concerning light-meter readings of the incident light at bamboo culms: In a previous year I had calculated that the plastic curtain on the meter cut down light 6-fold, and I used the curtain occasionally for the sky reading because it was too bright without the curtain. There is evidence that 6X is not appropriate, however, in all circumstances. Here are some test data: reduction with curtain Bright white wall (much brighter than clear sky) 6.1 X Blue sky 8.3 X Blue sky again 8.2 X Green fence in sun 7.7 X Shaded wall 11.5 X November 17- At La Veranada, clear blue sky, the sky reading on exposure meter at f8 ASA 100 was 1/100th second; the reading with curtain closed and meter pointed at bright sun was 1/240. A quick test of the reading on deep blue sky and sky with backlit nire leaves showed same reading. To the eye, the nire leaves look brighter, so bamboo under a single layer of leaves might be getting more light than "unshaded" bamboo (excluding direct sun, of course). Found a blooming bamboo at La Veranada. Sort of half-baked blooming, leaves not all dead, etc. A branchlet from one clump near our original marked clump was 160mm long and had 28 leaves and leaf scars. Another only 70mm long had 18 leaves and scars. November 18- Talked with Juan Chihuay who lives at 659 Elordi St., whose nephew Roberto runs one of the Hosterias at Pampa Linda. Juan was in the army at the time and remembers the blooming of thge bamboo on the Llao Llao peninsula in 1939. seemed quite sure of the date. It bloomed over the whole peninsula, and it all bloomed and died in the one year. He said that the seeds were produced in April-May and that there was an outbreak of rodents the next year. The rodents were smaller than water rats (Rattus) and had mediumm-long tails. He drew a good representation of an inflorescence and said that the seeds were like birdseed. He said that later (the next year?) it bloomed across the lake near Villa Angostura and the dead mice floated across the lake onto the shore on this side. When I said that Don Diego Neil said that it bloomed at Lago Puelo about 1940, he

Pearson - 1988 52_38 agreed that it bloomed a year later at Puelo. He said that Bernadino ?Huaynun? had an Estancia on the Llao Llao Peninsula but that the Park evicted everyone in 1936. The cows would have been removed about then, leaving a few horses maybe. Bernardino's father was born in 1799 and lived into the 1900s; he was indian. Lived partly on Isla Huenul, which was indian for sky; not Huemul. He remembers a rosa mosqueta bush at Nahuel Huapi in 1908, so there would have been lots around by the flowering of 1939. November 22- Puerto Blest. We have become increasingly aware of young clumps of bamboo, noted especially along the trail near La Cascada, near our marked bamboo clump on the grid, and along the trail to Cantaros just beyond the Post Office. These are always small clumps of small canes of graduated diameters; frequently we can find a dead clump within 5 m or so. The smallest culms, and presumably the earliest, are always short, smallest in diameter, and dead. Frequently they are branched. There may be 2 or 3 of them. The next larger culms are progressively larger in diameter, taller, and have more nodes, but frequently are dying back at the tip. We measured all the culms in one such clump near our measured clump on the grid, including leaf and leaf-scar counts on several branchlets of each culm. There are so many of these young clumps around, probably less than 10 years old, that we must conclude that there has been successful reproduction during our study. No mass flowering, but some seed production and successful sprouting. We still have not seen a "seedling". But it seems as though some of the clumps that flower do produce a few seeds, perhaps through pollination by a distant flowering clump or through inefficient self-pollination. A few viable seeds are then produced, not even enough for a ratada, nor enough to produce "a Buenos Aires wheat field", but enough so that the maverick out-of-sync bloomers are producing offspring. I continue to be impressed at the extent of parasitization of new shoots. At all of our study sites, a large percent never make it to full size. Escaping from parasites seems to be the most viable explanation of what drives the long-term, synchronous-bloom cycle. We walked our census along the Frias road from the south end of the camping meadow to El Abuelo, something like 2 kms, and counted 7 blooming culms on the West side of the road and 11 on the East (river) side. At least half of them were half-baked bloomings in which only a couple of culms were involved, or some culms had bloomed last year in part and were continuing blooming this year. One branchlet from the marked clump on the grid was 106 cm long, had 4 leaves, and 42 leaf scars. Another long branchlets from along the Cantaros trail was over 1 m long and had 52 leaves and leaf scars. Another not so long had 15 healthy leaves, plus some scars.

Pearson - 1988 53_33 Campsidium November 22- Puerto Blest. Rosendo Fraga says that the hummingbirds here are using mostly this vine fir food at this season. He is of course interested in coevolutions and is interested that something eats into the side of the tubular magenta-red flowers, thereby short-circuiting the pollination mechanism. He finds numerous flowers on the ground, many of them with holes in the side, and he doesn't know what makes the holes. He implied that some of the flowers up in the trees (it climbs on bamboo, bushes, and trees) have holes also, but I didn't get a clear idea of how many. He provided us with 3 or 4 blossoms that had been opened. Under a dissecting scope the holes look like they might have been made by mice, and in one of them the entrance was a double scoop just the right size for mouse incisors. None of the dozen or more blossoms that we picked up along the Lago Frias road had holes in them. The fallen blossoms contain the stamens but lack the pistil, which stays behind when the corolla falls off. We took some entire blossoms home and put two into each of three cages of Akodon longipilis. Within an hour, one of the blossoms had been bitten into on the side in a manner very similar to those gathered by Fraga in the wild. Wouldn't it be fun if the climbing endemic mouse, Irenomys, attacked Campsidium flowers? Some of the stamens of those attacked had been cut through. November 23- Bariloche. The captive Akodon longipilis at into several more blossoms, but they don't seem to eat the whole blossom. Maybe attracted by the nectar? The stamens are hairy at the base, which must act as a sponge for nectar, but the base of the stamens is not eaten.

Pearson - 1988 54_34_ Buneomys November 12- Bariloche. While puttering with the Buneomys manuscript and notes, I notice that I examined various types in the British Museum. The type of chinchilloides has "grooves near edge of front incisors", and the type of mordax has "grooves in center of incisors". Michael's two large specimens (?mordax) have grooves in center, and his three small individuals have grooves near the margin. The type of dabbenei, which is probably a synonym of petersoni, has "grooves near edge". It is a "small" form.

Pearson-1989 Journal October 13 - Bariloche. Arrived by plane at 2:30 p.m. The steppe quite wintery looking, but the temp was sunny, warm (18*C), and no wind on the lake. Apple and pear trees in full bloom, and tulips in town. Michael Christie came by. Says there was no snow in July, but some in August. Looks now like a light snowpack. There was rain in July when it should have snowed. The spring seems to be warm and dry. He tells about a c cliffy place on Estancia Primavera with deposits of tarry stuff and feces about the size of Phyllotis droppings. He brought samples, and also a jaw of a young Lagidium from the same place, plus a few droppings that could be Lagidium. October 14. Bariloche. Visited Gey and Isobel Gallopin. Morello is no longer in Parques, Fundacion Bariloche is in dire straits, at least the ecology section. The energy group is in charge. Rapoport has his own Ecotono Institute. Car started up OK. October 15 - Bariloche. Sunny, warm, light wind. Drove to Llao Llao at 4 pm. Only a few Scotch Broom blooms. Set traps in the first piece of woods beyond the Fundacion Bariloche house. Big coihue and cipres with bamboo understory. An old old fence post in the middle of the forest. The forest very dry. I set 36 Shermans baited with rolled oats and about 11 museum specials baited with canned shellfish paste from Chile, all these in forest. Anita in the same forest set 17 Shermans and 18 Museum specials. I also set 4 MS and 3 Shermans in a small, marsh, dense grass patch on the edge of the lake near Puerto Panuelo, hoping for olivaceus. Then camped in the forest at Lago Escondido. Bats at dusk. October 16. Llao Llao Peninsula. Night clear, no wind, fyull moon, not cold. Anita's traps in the forest caught 1 Geoxus dead in MS and 1 live Abrothrix in a Sherman. My traps in forest had 2 Oryzomys, 1 Dromiciops, and 7 Abrothrix. In the marshy grass were 1 Abrothrix in Sherman and 1 in MS. Total score: 89 traaps, 10 Abrothrix, 2 Oryzomys, 1 Geoxus, and 1 Dromiciops. Returned to Bariloche at 10:30 a.m. (daylight time) and processed mice. To Michael Christie's for tea. Saw Adam Hajduc on the way. He has Carbon 14 dating on an indian dig on Isla Victoria, close to time of Christ (60 yrs before or after). He says autumn was dry and that the snow didn't come until August, and even then it was mixed with rain, so the ski season was not good. The last month has been sunny and warm. October 17. Bariloche. Car lubricated, then exchange house (680/dollar). Patricia Fierro came after lunch. Says they had some rain the first week of September, but has been sunny and warm since then. Put out traps up on Cerro Otto, beginning at the marked bamboo clump and coming up the hill aalong the ski run that was cut last year and left

trunks and bamboo clutter along the sides. Good cover. The lenga leaves are well out, dandelions blooming, green grass in the meadow, cacho de cabra, and a few lilies well up. One patch of snow about 3 m in diameter, but everything pretty dry. The marked bamboo clumps have almost no yearling shoots, hence poor reproduction last summer. I put out 22 Shermans and 22 Museum Specials, alternating, rolled oats in the Shermans and corn meal on the MS. This is almost the same line as last year, except this year no traps below the road. Anita put 22 Shermans and 22 MS in similar habitat. She caught one Abrothrix while she was still setting. October 18 - Morning clear, night warm. Went up to Cerroí Otto at 7:30 a.m.. Anita’s line had 4 longipilis and 1 Auliscomys, all alive. I had 4 longi and 1 Aulisco. Two of the longis were in Museum Specials and the Aulisco, but I lost one of the longis on the way home (it was a female). Measured altitudes from the street in front of our house (2680 ft) to bamboo clump A@ on Cerro Otto (3790 ft) to the top of my trap line near the road (3900 ft). This makes the trap line from 1150m (bamboo clump 1158m) to 1180m. Processed mice. Saw Arturo Tarak, Marcelo Bettinelli, Christies etc. Earthquake in San Francisco. October 19 - Went to La Veranada and measured the bamboo clumps. Road still not paved, and the big equipment was working right up at the divide. Everything pushed around near our old campsight and the grid. Culverts e tc. hqave changed the drainage, but various streams still running. The meadow sort of green but very few dandelions, and everything quite dry. The nire just beginning to put out leaves. Put out 6 Shermans at one good spot when we arrived. Wehn we left, maybe 4 hrs later, had one female longipilis On the way down the hill, pulled off to the east at the south end of Lago Guillermo on a dirt road that goes into nire/bamboo near a big meadow at the end of the paved road. These nire also just leafing out. Very dense, small-leafed bamboo here, both the bamboo and the nire somewhat bigger and lusher than up above La Veranada. We were creeping along a narrow path in the bamboo, thinking we were away for everyone, when we practically bumped into Parkguard Flavio. He lives in the ranger cabin at La Veranada and had walked downstream to Lake Guillermo and was on his way back up. He has been here 6 months. He says that in hard winters they bring the horses from La Veranada down to here to graze, but since there was not much snow last winter, they didn’t do so this year and for this reason the grass down here was dense and lush, ungrazed, and the bamboo was ungrazed also. Back to Bariloche 6:30 p.m. Day was warm and sunny. October 20- Bariloche. Sunny and warm all day. Processed mice. Spectacular vaginal anatomy in Abrothrix. Juliana, Christie’s former secretary, came; says lots of mice at her place along Lago Mascardi. She says Akodon

longipilis, but her description sounds like Oryzomys. Patricia Fierro also visited, then dinner with Gey and Isabel Gallopin. October 21- Bariloche. Sunny, warm, no wind. Dissected Abrothrix. Susanna Martin and John Emlen came by. Supper in apartment with Emlen, who was with a World Wildlife tour group coming from BA and Peninsula Valdez. October 22- Bariloche. Day started out clear, then clouded over with high cloud cover, still warm, dry, calm. Drove to Llao Llao Peninsula with Emlen; saw Aragucarian pigeon in the bamboo/coihue/cipres forest near our marked bamboo, then up the Campanario chair lift (tucos under the lift), then to Lago Gutierrez, then to Laguna Los Juncos at Estacion Perito Moreno. The planted pine forests on the steep slope to the north of the road up to the first summit have burned completely, no new green visible. The lake is completely dry, the ground at Marful's powdery dry. Stopped for a couple of hours at our campsite near the brick-kiln meadow where we studied Reithrodon. Lots of weeds and dead thistle stalks along the railroad and between the railroad fence and the road. Many Reithrodon burrows and droppings in this weedy part. Walked across the meadow itself and saw quite a few holes but not many Reithrodon droppings. Certainly more sign in the meadow than last year, when, if I remember collectly, there was almost no sign in the meadow and very little in the weedy area. The fragrant Berberis bushes in full bloom. The caranchos have abandoned their old nest and built a new one in an adjacent tree. Stayed until 7:15 p.m. but saw no condors. Saw a pair of buzzard eagles (Geranoetes). Then dinner with Emlen at the Hotel Edelweis. The local guide with the tour group was Gabriel Benderski. October 23- Clear, windy, cool. In afternoon put out traps at Arroyo Pilmayquen on the east shore of Lago Gutierrez where Juliana and Claudio are caretakers on a lakeside residence (10 km SW Bariloche). About half the traps were along stone walls at the edge of the lawn of the big house (some bushes of rosa mosqueta but mostly Scotch broom). The other half in steep coihue/cipres forest typical of the Gutierrez lake front, along the old Bariloche/El Bolson road. Most traps in boulder slides in the forest (boulders from the big avalanche area on the new road above). I put about 31 Shermans and 2 cage traps, and Anita about 30 Shermans. Ground very dry; Scotch broom booms coming out. Then went to the flower show at SCUM. The tulips are mostly over, owing to the earliness of the spring. October 24- Picked up traps at 9 a.m. Two Akoo longi in the forest, 2 Ako olivaceus along the lawn/Scotch broom, 5 Oryzomys along the lawn/ Scotch broom, and 1 Mus along the wall of the house. Juliana's cat caught the Mus with great ease when I released it. There had been a big burn in Pampa de Huenuleo sometime ago. Green glass and dandelions were well up, but no signs of life in the bushes that had burned. They were being scavenged for firewood. Juliana says that many of the burns are set on purpose to provide firewood for the poor

Pearson-1989 20 bloom. Day sunny, mild, no wind. November 2- Bariloche. Clear, very windy. Hilda Rumboll came too call. She was about to be filmed by BBC Television in connection with her sighting of the Nahuel Huapi Monster many years ago. Her accounts are becoming temporally disconnected, Maurice is leading tour groups. In the evening a birding group arrived including Bruce and Jeannette Howard, the Whipples, George Peyton, etc. They had been to Peninsula Valdez and Ushuaia. Dinner with them and Michael Christie at Casita Suiza. November 3- Bariloche. Long visit from Hilda Rumboll. Talk to the Payton/Howard birding tour group including Narca Moore-Craig and Walt Anderson. Good weather. November 4- Bariloche, Nice day. Puttered with bamboo in apartment. November 5- Anita left with the Peyton bird tour. I left for the east about 11. Passed only 2 cars on the road to Pilcaniyeu (11-1 Sunday morning), and then only one car between Pilca and Comallo. Altitudes read along the way: Apartment 2730 ft, 1st Summit 3500, 2nd Summit 3400, Pilcaniyeu 3320, top of the bajada down into Comallo 3520ft, Comallo 2700 [and two days later: 9km W Clemente Onelli 3044 ft; bottom of the Comallo Bajada at the old school 2850]. Stillingia in full bloom at the bajada. The rocks where Anita and I saw viscachas a couple of years ago on the way to the steppe are 11 km by road east (really south) of Comallo. Stopped there briefly, lots of viscacha droppings. Then stopped for fox skulls at 13 km by road south of Comallo. Picked up 9 This is the place where we picked up some other ones 2 years ago on the way to Los Menucos, but then lost thjem to a dog when they were drying. They came from a heap of skinned carcases on the side of the road and seemed to include grey and red foxes. These specimens are from the same batch, only 2 years later. Then stopped at another cliff along the north side of the road 30km by road east of Comallo (or 10km by road west of Clemente Onelli). This is probably the place where Adrian found the dead Lestodelphys with Kirsch and Dickerman. I searched along the bottom of the cliff and found a couple of quarts of large owl pellets and numerous stray bones of tuco, Reithrodon, and Lestodelphys. Must have found 10 or more loose jaws and at least 2 pellets with Lesto in them. Then drove on to Clemente Onelli (41 km by road east of Comallo. Then turned around and went back to the Lestodelphys c cliffs, which is at km marker 475, 10 km B of Clemente Onelli by road. Camped in the scrub across the road from the cliff. Put out some assorted traps through the scrub/steppe, and then assorted traps along the bottom of the cliff hoping for Lesto. Day was warm, mostly overcast, windy at times but calm after sunset. November 6- 9km W Clemente Onelli. A gauch0 who rode through camp this morning when asked what this place is called said Clemente Onelli, and the estancia owned by a Sr. Cuesta. Last night had out about 9 cage traps, 35 Shermans, 25 Museum Specials, and 12 steel traps (total 72). some in great mousy looking places along the base of the owl cliff, some in bushy steppe. Line was

untouched except for 2 Phyllotis and one sprung empty cage trap with apple bait. Night was partly cloudy, calm. At daybreak heard the monotonous seed snipe, the gloaming whistler (winnowing of snipe), sounded like Peruvian altiplano. Also Cal quail and barn owl. At the base of the cliff is a grazed juncus mallin with a little bit of water, rising to dryer turf full of tuco/Reithrodon holes. The steppe across the road is sandy, with tuco burrows, rather lush bushes sort of like the bajada east of Comallo, with neneo, cola de pichi (Nassauvia), 2 kinds of Senecio, Stillingia (Sapium), and other thorny bushes, a couple of Berberis bushes, no duranzillo. Heard no tucos. Morning clouded up. A quick look at a few of the owl pellets picked up yesterday under the cliff indicates Ctenomys, Reithrodon, Phyllotis, Abrothrix longipilis (sic!), and Akodon xanthorhinus. No Auliscomyss yet. The owner came by. He was worried about fire because things are so dry. Says the Senecio bushes are dead because it is the 4th year of drought. He also says a big pale fox has appeared in recent years and that it is bad on sheep. He doesn't call it Zorro Colorado; has some other name. He didnt really respond to my talking about a small marsupial and showing him a jaw. Heard a tuco briefly in the morning: tucatuc, tucatuc. Caught one nearby later. That makes total catch 2 Phyllotis and 1 tuco. There is almost no bunchgrass in this sample of the steppe, and only scattered Stillingia plants. They are blooming and this morning some of them were swarming with ants up in the branches. Something nips off the branches, not just near the base but siometimes 3 feet up, even too high for hares. In a neneo tangle under one Stillingia was a nest made of 2-inch cut Stillingia twigs, containing mouse droppings the size of Phyllotis. This was at least 100 yards from the rocks. Picked up the trap line near camp, set others in tunnels at the base of 4 Stillingia, and rebaited the Lestodelphys traps at the cliff with tuco meat. Baited the Stillingia traps with canned tuna in oil. Forgot to mention 4 traps around a recently dead horse carcass; nothing. Rhea droppings. Then in the afternoon moved camp 1km east to another canyon with pretty much the same vegetation, a bit more Stillingia. Set traps in tunnels under about 10 Stillingia. You can find good tunnels under practically every Stillingia, and numerous ant tunnels but not necessarily ants. Maybe Notiomys is an ant predator? Morning overcast, afternoon clear. Warm, not windy. 8km W Clemente Onelli November 7- Night was thin overcast, not cold. The dawn bird chorus included a tuco tuco (tucacuc, tucacuc). The traps around about 8 Stillingia bushes (about 16 traps) were undisturbed. Picked them up. Then moved back down the road to 9 km W

Pearson-1989 22 Clemente Onelli where I had traps around 4 other Stillingia bushes and two in a tuco burrow (the one where I caught the tuco yesterday). This trap line contained one lizard (Liolaemus). Then picked up the traps under the owl cliff. This line contained 7 cage traps, 8 Shermans, and 9 steel traps, all baited with gopher meat. Two of them were sprung, but no catch. Total 50 traps. Hence in 2 nights, 122 trap nights, caught 2 Phyllotis, 1 tuco, and 1 lizard. Altitude reading here was 3044 ft. Altitude at Comallo Arriba at the school was 2850 ft. Stopped to take pictures at the school. While there, a local rancher stopped, Hugo Alberto. His chacra is 5km up the Comallo Valley. He raises alfalfa, sheep. says this old school was abandoned about 1972. There was a big, active, leaf cutter ant nest in theg'school yard. The railroad comes down the Comallo Valley here and meets the road near the school. November 8.- Bariloche. Did owl pellets and bamboo data. Lots of Lestodelphys in the pellets. Weather clear, cool, windy. Contents of the owl pellets from 9km W Clemente Onelli Ctenomys 36 Phyllotis 20 Reithrodon 38 Buneomys chinchilloides 13 Bligmodontia 33 Abrothrix 9 Akodon xantho. 29 Bird 2 Lestodelphys 20 Akodon iniscatus? 1 201 Note 10% Lestodelphys, range extension of Abrothrix, Absence of Auliscomys, and presence maybe of Akodon iniscatus. The Species Diversity Index is also notably high. November 9- Bariloche. Weather sunny, cool, windy. Owl pellets and bamboo data. Then drove out to Cerro Leones and set traps on the east side of the road to Pilca in the area that was bulldozed for roads and real estate development 2 years ago. The vegetation seems to be much less grazed than the slope up to the owl cliff on Cerro Leones itself. Lots of hare droppings plus some horse droppings. There is much more bunchgrass here, some of it with seed heads. Set 34 Shermans and 34 Museum Specials at 8 pm. Through steppe of mixed bunchgrass, Baccharis, neneo, Senecio, Colletia, Berberis, and a couple of maiten trees, only one rose bush. Much of the line was at the bottom of a rocky slope along the edge of dense Colletia. Slept in the neneo. November 10- Cerro Leones. Night mild, no wind, thin overcast. Morning cloudy, not windy. Traps held one live Phyllotis (released), 1 live Bligmodontia, 1 live young Reithrodon, 1 dead Akodon xanthorhinus, and 1 dead Oryzomys. Such diversity! Such scarcity!. Note no Abrothrix. Heard no owls. Back to Bariloche at 9 a.m. Adrian brought a copy of his thesis. His description of where he and

Pearson-1989 23 Kirsh and Dickerman found the dead Lestodelphys exactly like the cliff at 9 km W Clemente Onelli where I camped. He collected pellets there also (last year). Patricia Fierro will be local leader of a Smithsonian group next Friday, led by Susan Martin. Susana Antolache came by in the evening. She is interested in bamboo, especially impact of harvesting, commercialization, etc. I am not sure of her connection with the University or??She had a Veblen reprint from Bosque 1979 (Universidad Austral in Valdivia) that contained regressions for calculating volume of culms from diameters 1m above ground. She also brought Vol. 1 No. 2 of "Dendron: Informacion Forestal Andino-Patagonico". It is "environmental" with a silviculture slant. November 11 - Met Anita at airport, then to Llao Llao to measure leaves on L6 again. Clear, mild temp. Araucarian pigeon at Llao Llao; Scotch broom in full boom, and Notro (Embothrium). November 12 - Bariloche. Warm, clear, not windy. Julietta von Thuringen?? came by with 2-yr-old child. She is working on foxes still, and plans to extend her studies farther east. Says the trappers have recently begun to sell at least some of their fox furs through an official auction. Last year 9000 with the auction in Bariloche; this year 5000 in the auction, which was held in Viedma. But an unknown number trade through other channels. She says that a lot of the trappers have little 200-ha chacras on fiscal land (sort of government land held /for indians) and they probably trap all around and don't trust the government, so she is expecting to encounter a lot of cover-up. INTA gets 1.5 % of the the government tax receipts on the furs. John Jackson apparently is not coming back toi Argentina, Javier Bellati has his job, at least for the moment until there can be a concurso. Jorge Amaya is a higher-up. Rabinovitche's SPAIDBR program funds have been cut considerably by CONICET. She is going to do the annual mouse census at Campo Anexo next week and promises to tell me the results. November 13 - Bariloche. Sunny and mild. Javier Bellati came by, reported on things at INTA. He is still working on foxes, going to expand eastward, and also hopes to expand into raptorss such as Gerrhonoetes at Estancia El Condor. He says that at Los Menucos there has not been a drop of rain since a year ago September. El Condor not so bad off. Says that the Zorro Bayo (according to Crespo) is just a color phase of the Zorro Colorado, but it has a reputation of being more ferocious. Also reports that occasional red foxes show up at Campo Anexo of INTA. Then Thomas Beloch came by. He is hippy German, has lived herabouts for 10 years, and is editor of the silviculture journal "Dendron". It is supported by a German group. Their policy seems to be to promote sustained yield of the native trees rather than cultivation of pines, firs, etc. They are concerned especially about the cipres (Austrocedrus) which seems to bear the brunt of the pine effort, and also the cipres in moister habitats is suffering from a mysterious fatal disease. November 14 - Bariloche. Cold, clear, windy. Worked on bamboo. The bamboo girl,

Pearson-1989 24 Susana Antolache and her assistant Adriana came to talk about bamboo. Talk. November 15 - Clear, cold windy. Bamboo in the apartment. Alberto Sosa arrived from Santa Rosa. Santa Rosa has lots of rain. The viscacha habitat at Lihue Calel is improving and there are said to be some viscachas in the park on Lyn's study area. The New Zealander's red deer project at Parque Luro seems to be all tied up in political and administrative bungling. Alberto has not been able to get approval for a long-term bird census there. November 16 - Castano Overo. see Bhoospec account. November 17 - Night was clear, not cold. My trap line caught Abrothrix, Auliscomys, and Oryzomys. Found an overlooked Sherman from last year; it had a long-dead Abrothrix in it, plus? dog? toothmarks on the outside of the trap. Anita's line around camp caught Auliscomys, Abrothrix, and Oryzomys. Put out about 10 more traps in the usual log/dense Berberis, bamboo place near the bridge across the river. Then marked bamboo at the clamp in the forest. Lots of downed limbs and trees, no damage from grazing, but lots of sign of grazing on assorted bamboo. In the afternoon hiked up to the trapping grid. The trails not visible. Some cow pies on the grid, but no cow trails seen, so probably not a lot of impact. Lots of coihue and lenga seedlings and saplings, more coihue. Saw at least one clump of dead, flowered bamboo on the grid. Collected a sample of branches from the grid to examine leaf production and longevity. The auto road up the hill is closed in several places by treefalls. saw a Notro bush, some Berberis percei, and a bevy of small bamboo clumps with 4 to a dozen culms of graded diameter, but no mother dead mother bush nearby. The culms on the grid are smaller diameter than I had remembered. Chaura in bloom, and yellow violets. Anita and Alberto hiked up to the snow. I checked my traps: 2 lizards in the mallin, 1 Akodon olivaceus along the road. A condor landed up on the cliff above where the whitewashis, but then flew off. November 18 - Night clear but warmer. One Akodon longipilis in the new traps in the forst near the bridge. The other line had only one Oryzomys. Anita's line near camp had two young Auliscomys. Began to drizzle about 9 a.m. Gathered some branch samples from known-age culms, then drove to Ventisquero Negro and to the end of the road at Cerro Tronador. Was sitting in the car measuring bamboo when Susana Martin and Patricia Pierro appeared leading a Smithsonian tour group. They asked for a quickie lecture on the biology of the region. Back to Bariloche when the road opened at 4 p.m. Apparently no rain except at the Tronador part of the road. November 19 - Sunny, warm. Up Cerro Otto with Alberto to measure bamboo. Met the owner of Piedras Blancas ski run, but he was not a reliable informant.

Pearson-1989 25 November 20 - Bariloche. Measured bamboo leaves. Alberto returned to Santa Rosa. Letter from Gwenn Brewer indicates lack of rain at her coastal site in Buenos Aires Province (Bstancialos Yngleses) made her speckled teal give up nesting (in parrot nests). November 21 - Sunny, warm. Rosendo Fraga came by, then dinner with Javier and Ofelia Bellati. The census by him and Julietta at Campo Anexo (Pilcaniyeu) indicated very few mice. I think he said 80 traps for three nights made 5 captures. Anita and Alberto saw tracks in the snow above Castano Overo a mile or so short of the Refugio, that looked like mink or huron (Galictis). November 22 - Bariloche. Juliana and husband came by, then Adrian with manuscript for Mammal Society meetings. November 23 - To Puerto Blest on the launch. Some drizzle early, but then clear. The Scotch Broom on the way to Llao Llao is spectacular; Notro in Bariloche still blooming; Broom and Notro in full flower at Puerto Blest. Saw a Sephanoides hummingbird feeding on Notro at the Hotel at Llao Llao. A bumble bee was feeding on purple Columbine a few meters away. Marked new culms on our two marked plants (not many new ones), then censuses flowering bamboo along the road to Bl Abuelo. Twelve, which is about average. Dinner with Fraga in the hotel. He says he saw flies pollinating blooming bamboo at Iguazu, and that in the forest there is not enough wind to rely on wind for pollination. His Campsidium is in bloom. We saw many flowers; many of the ones lying on the ground have been pierced, but we saw only one that looked eaten like the ones last year. November 24 - Puerto Blest. Night clear, day clear. Visited with the new park guard, Javier, who used to be at Lago Espejo. He is alert to the bamboo cycle, told us where several blooming plants were, and said that at Lago Espejo one of the natives used to raise pigs and that when the bamboo set seed in about 1944, the pigs got fat on rats and mice. Then we hiked to Lago Cantaros and along its north shore towards Lago Ortiz Basualdo. Nice forest, a few large alerces and a few young ones, lots of Saxogothea, lots of bamboo. None blooming but numerous young clumps. Home on the 4:30 launch. November 25-26 - Bariloche. Worked on bamboo and on Monjeau manuscript. Weather sunny, warm. November 27- Partly overcast in morning, no rain. Drove to Villa Angostura then to Ruca Malen. The road to Angostura is about half paved, the other half worse than ever. There is huge project of new bridge and road improvements going on at Ruca Malen. The hotel there seems to be all set for guests, but we saw no signs of life. Camped at the Aconaemys site on the bluff overlooking Ruca Malen. I put out 30 Shermans and 30 Museum Specials in bamboo/coihue/chaura forest, not many good logs. A few nires also. Anita put out 40 in dense bamboo. We found no signs of Aconaemys. November 28 - Ruca Malen. Night clear, warm. Nothing in my traps; 4 Ako. longipilis in Anita's, all in Shermans. This must be the worst trapping since the night with Felipe Valverde on ?Cerro Otto in lenga forest, when we caught nothing. Then we drove home down the Traful Valley to

Pearson-1989 26 Confluencia. Some fairly new sign of tucos at the usual place 10km NNE of Nahuel Huapi, and at another similar site 1 km farther north. Fraga for supper. November 29 - Bariloche. Weather warm and sunny. Went with Adrian Monjeau to the tuco place along the highway. The first place, our usual trapping site, is 12.6 km by road NNE of Nahuel Huapi, and the second place is 1 km farther north. I am calling them 10km NNE and 11 km NNE. At 6 p.m. we set 11 steel traps on the west side of the road at 10km, 6 at 11km on the east side, and 1 at 11km on the west side of the highway. Several tuco nests were uncovered looking for good sets, plus grass plugs, etc., but no signs of recent digging and no vocalizations. 11km seemed more active and with less digging by hurones/skunks/armadillos,foxes. Just before dusk I set 18 Shermans in the sheep trail (between two fences) at 11km on the east side of the highway. Rather rich bushy, sandy steppe with neneo, Senecio, coiron. Checked the tuco traps before dark and already had 1 adult (by the tail) at 10km and two adults not seriously damaged at 11km. November 30 - 11 km NNE Nahuel Huapi. Night mild, clear. At 2:30 a.m. the 7 tuco traps at 11km had not been touched, but at 7 a.m. a trap right next to the car held a second adult tuco. I was sleeping right next to this (and other burrows) and heard no vocalizations. One burrow at 10km at 9 a.m. had been plugged. Reset the trap, but nothing caught by 10 a.m. Two adult Reithrodons in the 10 km traps, however. The 18 Sher mans held 1 Reithrodon adult, 2 Akodon xanthorhinus, and 3 Bligmodontia (sic). The first ones from the Cullin Manzano massif. They are very short-tailed. Returned to Bariloche at 10:30, built shipping cages, and then Adrian shipped four tucos, 1 Reithrodon, and 2 Bligmodontia to Reig. Gwenn Brewer and her field assistant stopped in. Her ducks in Buenos Aires Province dried up. They have seen rheas slip between the wires of sheep fence. Pedro Pietro, the ex-parkguard from Puerto Blest and now at Lago Bspejo, stoppped in with advice about where to find the strange bamboo at Lago Frias: right along the road at the border with Chile. December 1 - Bariloche. Weather has turned cold and drizzly, with some hail. Adrian and Fraga visited. Bambooood. December 3 - Flew to Buenos Aires. December 4 - Annual meeting of SAREM (Argentine Mammal Society), Fernando Kravetz president. There were about 50 people present, about 20 posters on the walls of the 4th floor of Pabellon II of the Facultad de Ciencias Exactas y Naturales in Nunez, plus symposia and round tables. Kravetz and his group and ex groupies were in evidence, Jaime Polop was there with three posters, Christina Busch with tuco posters, Martha Piantanida with an Akodon growth poster, various Calomys/Akodon in cultivated fields papers. The Primate symposium was attended by a totally different subset of people. Dr. DeCarlo appeared briefly; he is retired and practising medicine. Reig was much in evidence at the business meeting and tried to postpone the

joint meeting again. Roig was there but kept to himself. Zuleta and Vitullo did a lot of the running of the things, Susana Merani forcefully expressed her opinions in the business meeting. The plan is to have as many as 10 symposia in the 3-day joint meeting, each symposium jointly headed by an Argentine and a Yankee. Much enthusiastic discussion about mice with Gloria de Villafane, Patricia Marconi, Maria Isabela Bellocq, and David Bilenca. If I understood correctly, next year's meeting will be in San Luis. Adrian, as winner of the Society's annual prize, gave a fine talk, and Bibiana Vila was awarded a prize for her vicuna article in Ciencia Hoy. I gave some Lestodelphys skeletal material to Bianchini to deliver to Pascal in La Plata. December 5 - More Mammal Society meetings. Visited Martha Piantanida's Akodon colony. Saw a litter of 2-week-old longipilis. She says they didn't breed until she put them into a big cage with a plastic feed sack in it, under which they made a nest. She has not been gathering data. Then lunch with Jim Mills and his wife. They are on a Junin Virus project between Johns Hopkins and the Hemorrhhaig Fever Institute in Pergamino. They are doing small-mammal censuses etc. near Pergamino. She is a botanist, he an "ecologist". Then visited Reig's lab which is 50 ft. from where the meetings were in session. There were 6 or 8 people working in the lab, some of them processing the tucos and mice that Adrian and I sent last week, but as far as I could tell none of his group was participatiung (or attending) the meetings. Maria Alicia Barros was there, and Marcelo Ortells gave me a reprint of Bligmodontia caryotypes. Probably a northern species (Peru/Bolivia/Chile) and two or more southern species, the one in Neuquen (and probably Bariloche region) without a name. There was little participation by people from La Plata, nobody from Tucuman, and neither Ojeda nor Julio Contreras. The slate of nominees was Susana Merani for President and Julio Contreras for VP. Presumably they were elected. We left before the clausura. Tea with many of the Nottebohm clan. They say that things are very dry at La Maya (Cordoba Province). December 6 - Flew back to Bariloche on the early flight. The steppe still looks dry, but the mallin at Estancia El Condor has turned green. Rosa mosqueta has started blooming; Scotch Broom and Notro still blooming but tired. December 7 - cool and cloudy. Resfriado. Dinner at Tarak's with Christie, Mane, brother-in-law Alejandro Abedissian and wife Aspe. December 8 - To La Veranada with Gwenn Brewer and Josh Brown. Took some leaf samples from marked clumps, and waklked up into the woods along the woodcutters road beyond our study grid. Just after passing through the nire and getting into the lenga, we found two flowering clumps off bamboo., I think these are the first we have found at La Veranada. Perhaps it is sugnificant that they were both in the lenga forest on taller, longer- leafed culms. Then drove down to the south end of Lago Guillelmo and set traps in nire/bamboo/lush green grass. Obviously not much grazing pressure there

Pearson-1989 28 this year. Drizzly, quite wet. I put 30 Shermans and 30 Museum Specials, mostly in bamboo clumpns along a road and path with lots of grass. Anita put 20 Shermans and 20 MS, many of them at the base of nires. Returned to Bariloche. The lupines at Lago Mascardi in full bloom. December 9 - Back to La Veranada to pick up the traps. Catch as follows: Shermans Museum Specials Total Ako longipilis 7 2 9 Ako olivaceus 3 1 4 Auliscomys 4 7 11 Chelemys 2 0 2 Geoxus 0 1 1 Oryzomys 0 1 1 28 Saw numerous hares here, a few tuco diggings. Day mostly cloudy, windy, a few sprinkles. Adrian came in the afternoon and took the two live Chelemys, presumably for Reig, although they are both females and Reig already has some females. December 10 - Bariloche. Rain. Analyzed bamboo leaves. Long visit from Gwenn Brewer and Josh. December 11 - Rain in morning, cleared in afternoon. Conference with Adrian. At 6 p.m. set traps at Rio Casa de Piedra, 12.7km W Bariloche. Cloudy and some drizzle. I put 35 traps alternating Shermans and MS upstream from the bridge on the west side of the stream. Steep slope with lenga forest with boulders, bamboo, a few logs. Anita put 10 Shermans and 10 MS on the NE side of the stream in retamo, radial, shrubs, and green grass. Then we drove 1.2km east and I put 11 Shermans and 11 MS alternating around an ungrazed meadow in retamo, colletia, radial, nire, mmutisia, green grass, tuco burrows. Anita put 10 and 10 traps ocross the road in scrub nire, brush, and acaena. She caught one Akodon olivaceus before she got back to the car. December 12 - Picked up traps at 8 a.m. At the Rio Casa de Piedra I had 3 dead Oryzomys, 1 dead longipilis, 5 live longipilis, 1 live olivaceus, and 1 live Oryzomys. Anita had 2 dead Oryz, 2 dead longi, 1 dead Geoxus, 4 live longi, and 2 live Oryz. At 11.5 km W, I had 2 dead longipilis, 1 dead Auliscomys, 2 live Oryzomys, and 2 live longipilis. Anita had 2 dead longipilis, 1 dead olivaceus, and 1 live longipilis. Summary: Shermans Mus. Spec.

Pearson-1989 29 Note that the trapping has improved enormously since October/November, yet only two of the catch were juveniles. Day became increasingly sunny. Processed mice. Bern\ey (Jehovas Witness) visited, then Patricia, then lunch with Gwenn and Josh. December 14 - Bariloche. Michaael Christie visited. Then set traps with Adrian Monjeau at 11km NNE Nahuel Huapi. Evening mild, calm, full moon. I set 26 Shermans and 26 MS alternating, between the two fences along the highway, and Adrian set 27 Sher mans, same habitat. Sandy soil, neneo, Senecio, a little bunchgrass. Lots of hare sign. Slept next to the tu cos, but heard none during the night. Picked up traps at 8 a.m. Adrian had 4 Akodon xanthorhinus and 2 Bliigmodontia. I had 7 Bligmo andf 3 xantho. 6 of mine in Sher mans, 4 in MS. Then visited the Parques office (Carlos Martin, Monica Mermoz, Eduardo, and Chehebar. Chehebar was off looking for a lost otter. Talked with Monica about bamboo. She had a written report and map from the park guard at Tronador giving locations of blooming bamboo plants, but no mass blooming. Met Michael Christie and Laurance Sympson at Estancia La Primavera at 6:30 p.m. Sympson drove us to a rock spire at the river end of a terminal moraine about 2km downstream from the ranch headquarters. On Baily Willis's topo sheet seems to be 10km NW Confluencia. There is a raptor perch on top of the spire, and a cave on the upstream side of the cave (with a family of torrent ducks in the river below). The cave is not deep or dark, more a scooped out place with a lot of fallen rock on the slanting floor. In places are accumulations of handfuls of mouse droppings of about Phyllotis size. In a few places are old Lagidium droppings. Sympson has not seen vizcachas here. In places, packed under rock slabs or in rocky crevices are black or dark brown accumulations of organic/material, sort of like peat but frequently denser. When picked up or pried loose, these accumulations may or may not have individually distinct rodent droppings incorporated in them. There may also be a stratification of old grassy vegetable fiber. In other places are rounded masses of hard, black, shiny, tar-like material. These blobs are sometimes fastened directly onto clean, vertical, or even overhanging rock surfaces and have to be knocked off by powerful blows with a rock. There seems to be a gradation of hardness from peat to obsidian. Also lying among the rocks on the ground were assorted loose bones and predator droppings from weasel size to fox size. No owl or hawk pellets. Among the bones picked up by the three of us were Phyllotis, Akodon longipilis, Reithrodon, Buneomys, small bird, lizard, and snake (curved mandible with backward-pointing sharp teeth). Also a few small droppings composed of orange crustacean parts, a few Buneomys droppings. One dropping, or pellet, rather tightly compacted,

Pearson-1989 30 seems to contain only skins, bones, scales and claws of lizards. Especially noteworthy were two broken crania of enormous tuco-tucos with very wide incisors. One chunk examined under the dissecting scope seems to be a conglomerate of rodent droppings, pieces of plant such as twiglets of cipres, small bones, all cemented into a hard mass by a hard tarry substance. Then we returned to the ranch headquarters, and Michael and I drove upstream past the shallow lake to a place where a huge cliff looms above the trail with maitens, berberis, Colletia "trees" etc at the base. Beginning at 10 p.m. I set 12 Shermans and 7 steel traps in cavy places and at the bottom of this cliff. No good sign. It was up on top of this c Cliff somewhere that Michael collected other samples of the tarry cave material. Camped in dry mallin at the bottom of the cliff. Dec. 15 - A wind came up during the night, and light rain. Traps held one large Auliscomys. Back to Bariloche at 10 a.m. Scattered clouds. Interview with Thomas Belloch, editor of Dendron, and his friend Linder. Dinner with Patricia Fierro and Jorge Valerini. Dec. 16 - Bariloche. Tried phoning BA re: delivery of specimens. No luck. Dinner and Children's Christmas Chorus in the cathedral with Arturo, Mane and Sr. Tarak. Dec. 17 - Both captive female longipilis gave birth. Tried phoning BA; no luck. Morning overcast. To Lago Gutierres for barbecue with Juliana and Claudio. They showed an ad for a 15000ha estancia on the shores of Lago Buenos Aires (Santa Cruz) with 8000 merino sheep, and spectacular casco... for U$S 650,000. At 9 p.m. we went to Arroyo Casa de Piedra. I set 27 Shermans in about the same line as last week in coihue/bamboo/rocks, and Anita set 27 as last week in radal/scrub. Evening mostly overcast. December 18 - My line had 4 Ako longi and 2 Oryzomys. Anita had 5 Ako longi, 2 Oryz, and 1 big Auliscomys. One longi escaped in handling, the Oryzomys and Auliscomys were released. Morning scattered clouds. Ctenomys called several times during the night and at daybreak. The call had 4 or 5 tucs in each element, separated by about 1 second. The San Ramon ones are shorter tuc-a-tuc. Processed mice and built shipping tubes. Christie, Gallopins, Patricia, Adrian all came to call (same time), then dinner at Rapoport with Adrian and Inez. December 19 - Bariloche. Packing and despedidos. December 20 - Took 7 live Akodon longipilis to Buenos Aires and delivered them to Martha Piantanida at her Animal colony.

Pearson-1989 31 Abrothrix longipilis October 17 - Bariloche. Caught 10 yesterday on the Llao Llao Peninsula. 5 of the males had large testes and accessories, and 3 of these had lots of zoa in smears of the epidid. The other male was caged with a female with cornified smear. All 4 females had open vaginas. Two dissected had distinct corpora lutea, no zoa in smears, one of them with leucocytes and one with nucleated epithlial cells and cornified cells. One caged with male had nucleated smear, other caged alone had cornified smear. The pair did not mate overnight. October 23- Caught 2 Akodon olivaceus today and noticed that they squeak when handled, whereas longipilis does not. A helpful field character. December 11 - A male killed by cervical separation yesterday had a white rubbery plug of semen extruding from the penis. This suggests that Abrothrix is capable pf forming a vaginal plug, and the fact that we have never? found a plug in a female suggests that they do very little copulating. December 18 - Arroyo Casa de Piedra. 54 Shermans caught 10 Ako longi, 4 Oryzomys, and 1 Aulisco. One adult longi escaped, leaving 3 youngish males (but not juvenile), 4 adult males, and 2 youngish females with open vaginas. Smears of the females not estrous, no zoa.

Pearson-1989 #32 Akodon olivaceus October 24- Bariloche. Caught two females at Lago Gutierrez. Both were pregnant, bot had small simple ovaries with appropriate numbers of pink corpora lutea to match the number of fetuses. The vaginas were not as wide and tough as longipilis. See pickled ones for comparison with longipilis. Hence, no evidence from the female UG tract that olivaceus is an Abrothrix. When handled on two different occasions, both of these olivaceus squeaked, whereas longipilis does not. One of them had one or more liver cysts. December 9 - Lago Guillermo. 100 traps in cana/nire and lots of tall green grass caught 4 olivaceus. One not saved: M 130 39 22 13.5 11.5g Testis 6mm, white; epidid tubes not visible. SV 2mm. No zoa in smear of epidid. December 12 - Rio Casa de Piedra F 170 75 22.5 16 25g Vagina not open. Nipples medium large, no milk. Uterus with faint scars - 2 right, 2 left. Vagina 2mm. Right ovary, 6 CL, various stages of pinkness; left ovary, 8 CL oof different sdtages of pinkness. pelvis open.

Pearson-1989 33 Akodon xanthorhinus October 29 - Estancia Condor. 60 Shermans set mostly in habitat appropriate to xantho caught 2 xantho, 1 Oryzomys, and 9 Ako longipilis. Picked up traps at 8 a.m. and returned to Bariloche at 10 p.m. When I removed female 7677 at 10:30, she was giving birth in the trap. Put her by herself in a cage. See catalog entry 7677.

Pearson-1989 Auliscomys micropus December 9 - Lago Guillermo. 100 traps in nire-bamboo with lots of lush green grass caught 11 Auliscomys. Four were released, between 25 and 50g. The following 7 were dissected: 95g F open vagina. Nipples large. Uterus with 7 conspicuous scars. Ovaries with big pink corpora lutea. 30g F vagina open. Uterus 1mm, white, no scars. Ovaries developed, but no corpora lutea seen. 30g M Testis 5, white; sv 2. 28g F vagina not open. Uterus 1mm, pale, no scars, ovaries no corpora lutea. 17.5g M Testis 4mm, white; sv 2. 18.5g M Testis 4mm, white; sv 2. 16g M Testis 4mm, white; sv 2. The tail skin slips off easily when live animals are handled by the tail. Young 30-g individuals seem to be coming into breeding condition. December 12 - 11.5 km W Bariloche. Caught a big adult at the edge of a meadow in nire/radial/retamo/mutisia: 78 g female, vagina open, nipples large. Pregnant. Fetuses 20mm CR: 2 right, 1 left.

Pearson-1989 #36 short, live culm with a dead top, and 27 dead shoots. At least 20 of the 27 death shoots had been parasitized. So 43 shoots had appeared last summer in this clump, 15 of them were healthy (35%), and at least 47% had been parasitized. One new shoot was just emerging. October 30- Cerro Otto. Measured clump A1 out in the open field. Only 1 yearling culm and NO dead shoots. The yearling was smallish but not parasitized. October 31- Cerro Otto. Measured clump A2 in the forest. It had produced 14 live yearling culms and 16 dead shoots. All 16 of the dead shoots had clearly been parasitized. 10 of the 14 yearling culms had dead tops, and 9 of these had been clearly parasitized. So this clump had produced 30 new culms of which only 4 were healthy and 25 had been killed or truncated by parasites. November 1- Llao Llao Peninsula. Counted leaves and yearling culms. There were 11 living yearlings (1 of them with dead top), 7 dead shoots, 4 of which were definitely parasitized. So, total production for the year of 18 new culms; 10 of them healthy, 7 died in infancy, at least 4 of them killed by parasites. November 11 - Llao Llao. Measured leaves and interleaf distances on marked leaves on plant L6. Then checked the bamboos on the side trail. The one that we decapitated 2 years ago is now essentially dead; still a little green color in the bottom few internodes but no leaves or branches. Two other adjacent culms of the same size that had the tops killed by parasites are almost dead; only two leaves on each of them. Two nodes on a healthy culm that had all the branches removed (from these two nodes) had produced no new branches. On the way out lying in the trail was a big fresh culm about 1 inch diameter that someone had cut. Two internodes near the base had neat 3.5 mm exit holes (one in each internode) and tunnels inside of the internodes full of frass. They were in adjacent internodes but did not pass through the separating node. The culm itself looked green and healthy. November 16 - Castano Overo. With Anita and Alberto Sosa to our campsite on the Rio Castano Overo. Lupines just beginning to come out, some Berberis darwini out, B. linearifolia has berries. Saw one flowering bamboo along the Rio Manso. Measured bamboo at the clump by the road. 10 dead shoots, 9 of them parasitized. Then set out traps alternating Shermans and Museum Specials. About 24 in the mallin in grassy/juncus/bushy places; squooshy underfoot (but the road in was almost dry). Also put about 20 more along logs in bamboo and forest along the road. Weather sunny and warm, no wind, and heard no glaciers. November 17 - Castano Overo. Checked the clump in the woods. It had about 8 new live yearling culms and 2 dead shoots, both of which were parasitized. Collected branch samples from a known-age culm for analysis of leaf

Pearson-1989 production and leaf longevity. Found a dead, flowered clump on the grid. Also, slightly below the grid, a swarm of young clumps with 4 to a dozen culms of graded sizes, but no dead mother clump nearby. A collection of branches from the grid had produced: 3+3+3 leaves, 2+3 leaves, 2+2+3 leaves, and 3+3 leaves. See also analysis of the branches from the 1984-85 culm. November 23 - Puerto Blest. One big clump at the south end of the camping meadow is half blooming; seems to have half bloomed last year, probably after we had been there, and half is blooming this year. We measured iour two study clumps (production quite low), then walked the road to El Abuelo and back: 9 blooming bushes on the Rio Frias side of the road, 3 on the opposite side, 12 in total. November 24 - Puerto Blest. Walked to Cantaros, then along the Lake at the top of the steps toward Lago Ortiz Basualdo. Beautiful forest, lots of bamboo, but saw none blooming. Numerous places with small groups of young bamboo, sometimes with a dead mother clump nearby looking dead many years. Pressed one particularly small, 4-culm "clump", one of the culms a brand new shoot with tiny leaf at the tip.. During this walk we saw very few plants with small dead shoots; apparently that kind of parasitism is not common this year. Here is leaf production and longevity of leaves, deduced from reading leaf lengths and leaf spacing along individual branches. The first column of each pair is number of leaves and scars visible for each year; the second column of each pair is the number of leaves surviving on 11/23/89: Puerto Blest, Clump D1, a culm older than 1934-84 Year 88-89 87-88 86-87 85-86 84-85 83-84 82-83 81-82 No.leaves 39 36 44 29 38 13 30 1 14 0 11 0 5 0 2 0 No.branches 15 15 14 11 5 5 3 1 Av.no.leaves and scars 2.60 2.93 2.71 2.73 2.80 2.20 1.7 2.0 % survival 92.3% 65.9% 34.2% 3.3% 0% 0% 0% 0% The above 15 branches included 9 long ones up to 23 inches long and 6 shorter ones. 4 had dead tips. *************** Culm No. 3 1983-84 in Clump D1 at Puerto Blest 11/23 Year 88-89 87-88 86-87 85-86 84-85 No. leaves 37 35 41 31 35 10 22 0 8 0 No branches 14 14 14 8 6

November 27 - Drove to Villa Traful, then north to Ruca Malen. Three clumps of bamboo in full bloom along the road near the south end of Lago Espejo. They were 50 and 100 m apart. Then no more until near the Park ranger station, where there were 2 more, then no more until one near POrtezuelo. At Ruca Malen the leaves are short-lived: few branches had more than 4 or 5 leaves. Annual production seemed to be 2,2,2,3 leaves. Lots of big erw shoots, a few of which had been broken off and eaten (cows? horses?). Very few dead shoots, and few of them parasitized. Saw small white moths flying around the bamboo at dusk and early morning. Some gorgeous big clumps in this forest, plus medium sized and in places lots of young clumps of only a few culms a couple of mm in diameter. If blooming is synchronous in a forest, all plants should be of the same. These are not. Therefore.... Excavated A small clump aloing the edge of the road a little north of Portezuelo on the Traful drainage. Saved the roots, rhizomes, and lower part of stems to get a relationship between culm diameter and number against biomass of roots and rhizomes.

Pearson-1989 39 Dromiciops October 16 - Llao Llao Peninsula. Caught one in a Sherman trap baited with rolled oats. Seemed sick, dispirited. In cage when it did become active it ran round and round frantically. No testes visible. No vocalizations. October 17- Captive ate apple and Oryzomys carcase overnight. Did not seem to eat German celery greens or canned shellfish paste. Was more alert in the morning, but still doing round-the-rounds on the floor of the cage and upside down from the wire top. Did not eat Mar del Plata cheese, nor dulce de membrillo. November 22 -- This captive has been eating only apple and mouse carcasses. Seems to prefer liver, kidneys, etc., but does not consume very much. Its tail has not become fat. Lately, it has been catching flies in its cage during the daytime. Rather adept at it.

Pearson-1989 Lestodelphys November 5 - 9km W Clemente Onelli, Rio Negro. Stopped at a cliff on the north side of the road and found about 1 gallon of owl pellets and assorted stray bones lying on the ground including tuco and Lestodelphys. Decided to camp and try for Lesto and Notiomys. The cliff rises out of a mallin with juncus and some water at one end of the cliff. Then dry juncus with Reithrodon burrows and, across the road, bushy steppe much like the bajada into Comallo but lacking duraznillo. Lots of neneo, Naussavia, the dark green Senecio, sparse bunchgrass, a few Stillingia, fairly abundant spiny yellowwood, and very few Berberis. Soil a fine sand, light, lots of tuco burrows. Set 25 traps under the cliff for Lesto: jump traps, cage traps, and Shermans. Baited with apple or no bait. Across the road set a line through the steppe hoping for xanthorhinus and Notiomys. November 6- Traps caught 2 Phyllotis and 1 tuco. Rebaited the cliff line with tuco meat. Then set another short line 1 km east, all in burrows under Stillingia. Heard barn owl. November 7- Traps caught 1 lizard, period. Lestodelphys common in the pellets. This may be the cliff where Adrian found the dead Lesto. November 8- Have dissected part of the pellet collection. Ten pellets had Lesto in them, plus stray mandibles and maxillaries picked up loose under the c Cliff. One pellet had two Lesto in it! The wooly Lesto fur is distinctive in the pellets. Most of the bones seem to belong to young individuals. The owner of the estancia, Sr. Cuesta, didn't seem to distinguish a marsupial in the local fauna. He is worried about the 4 dry years in a row. Can the striking absence of small mammals be the result of an outbreak of Lesto last year? Can hardly blame the owls, since mice have been abundant under numerous other owl cliffs.
