Established camp ~ 2pm today adjacent to irrigated pasture where gopher activity looks high. re < 1week mound densities (nearly all fresh) old are high -> probably from 20 to 50 / acre. The pasture is bounded by the KITZ MILLER RD - Fort Romie Rd intersection immed. to the NW. The owners were glad to give permission to me, provided I took the gophers I captured with me. Haven't much choice with the kill-traps. The pasture is ~ 20 acres, composed mainly of clover and (unk) grass in varying relative densities. Ground cover is 100% except where gopher mounds surface.

Things picked up considerably this afternoon - total gophers caught now up to 9. #s 101 through 108 came, for the most part, between 2 and 3 pm. I'm on my way now to pull up all traps for the night. 4 December. 11 am. Nights here are quite cold - w/o a thermometer, I'd say last night's low was ~40°F. Mornings are foggy w/ low visibility until 9:30 or 10:30 am. Accidentally left 2 traps in ground last night - both had gophers in them (#s 109,110). #110 was still alive, #109 was recently dead. Both yielded ample blood samples. 109 & 110 were caught ~7 am. 20 traps or more are out, yet nothing since then. Those traps in the same hole since 2 December were moved, 4 or 5 holes had to be re-cleared of fresh material. Apparently the gophers are

Just returned from taking up the traps and collecting 3 soil samples. Samples were taken from inside burrows at 3 points: bottom of the slope, mid slope and upper edge of slope. Colors range from light to dark brown perhaps due to moisture conditions (moister & darker at bottom of slope). Soil is sandy. The purpose of the samples [illegible] is to coded match them with colors from the Munsell color chart.

D. Brylski 1977 Journal 0.2 miles south Mission la Soledad, Monterey Co. California 4 December the gophers 4 or 5 times in this way. In short, my trapping effort remained high for a dwindling population. Those remaining seemed better at evading my traps. I do have much to learn in techniques of gopher trapping.. 13 January 8:45 pm Arrived last night in middle of light rain. This [illegible] gopher mounds were smoothed over by rain-drop action, allowing me (still) to determine fresh mounds. Those were the mounds without rain-drop sign considering that the rain stopped half thru the night. Fresh sign was not numerous on this 20 acre pasture. Over the 20 acres I estimate 30 mounds were fresh at 7 A.M. Unfortunately, caught only 3 individuals (#s 111,112,113). Factors contributing to poor success were: experienced gophers, occasional rainy weather. Roughly 20 trap days were accomplished yielding a 15% trap success. Tomorrow I intend to start trapping the second locality - perhaps I'll return here Monday the 16th to complete the 15 for this locality.

Bryliski 1978 Journal 0.2 miles N, 0.2 mi E Mission la Soledad montery co California 14 January 8:15pm Today's rain prevented me from accomplishing almost any work. It poured nearly all day. Around 9am I investigated a second locality - while digging around in the rain, mistook a horse manure pile - saturated - for a gopher mound. This signaled the time to move on. Drove south to King City and NW to San Benito, the third point in this first transect (Hastings Reservation first, Soledad second). San Benito was, for the most part, flooded. I had hopes of diminishing rains to the east of here but such was not the case. Returned to Soledad and began reconnaissance for 2nd sample for this locality. Several hundred feet from 1st locality sample site asked several farmers for permission to trap their pasture. They directed me to newly plant barley field ~1/2 mile N, 1/4 east of 1st site where gopher sign is quite numerous. Set 15 traps at 3:00pm, caught # 1/4 at 4:30pm. Tomorrow will continue sampling here for 2nd 15-20 animal sample.

P. Brylski 1987 Journal ~2 km west highway 86 (Salton City) on County road 522, Imperial Co., California 22 March Snap traps were spring. None of the line traps were spring. I guess there was little interest on the rodents' part in my traps. The Museum specials were baited up peanut butter - oats - tearl seed mixture; the line traps all had a ball of cotton & half-handful of seed-oat mixture. It's also likely the fox robbed some of the snap traps. Better luck tonight, I hope. 23 March ~5 km NE Glamis along Hwy 78, Imperial Co., Calif 2 pm drove here this afternoon / morning from Brawley. I searched for several hours for suitable habitat to catch heteromyids. Just west of Glamis is several miles of dunes covered w/ sparse vegetation. Access is very limited & that which exists is fully utilized by ORV recreation- ists. I drove past this site, NE to County road S34 & drove south ~8 miles. That area is 1000'ft or so higher in elevation than there; the vegetation there is extremely sparse - very rocky, rolling terrain. Here the vegetation is moderately sparse "scrub" (for lack of better term, not being familiar w/ the flora). Dozens of washes cut across the terrain - small washes (several meters across).

It certainly isn't a willow (though the other is acacia stelleri). Ocatillo occurs here although sparsely - and on the flat rocky pavement [illegible] pavement. There are several gravel-hills but this area is mainly flat or rolling gravelly- sandy terrain, cut frequently by washes. Plant cover approaches 30% in few areas, but on the whole is ~ 10-15%. Rodent burrows abound. I set all traps this afternoon - 15 line traps (10 large, 5 small) and 30 snap traps (museum specials). Because my poor luck last night (no captures), I baited the line traps w/ peanut-butter & seed-oats mix. And provided cotton (which I did last night also). The traps were spread out over an area roughly 1/2 hectares in 4 lines. 24 march 5 pm Checked the line - had fairly poor success again. ~10 animals which were stuffed this morning and afternoon (See catalogue).

If things get too slow, I'll try a rock. 8:30 pm Spent the day stuffing kangaroo rats (Merriami), mice (P. eremicus), ground squirrels (A. leucurus), and a pocket mouse (probably Perognathus but it lost its tail so identification is difficult). Also caught several Perognathus sp. which today were kept alive. They're probably penicillatus but perhaps Formosus. Weather here is quite warm - round 25°C by 9am (probably by 7am actually), reaching 35°C in the afternoon. No clouds. Wind is unremarkably most of the day, but gusts up round 3 or 4 pm. At times it's 35-40 mph (mainly from the west) but the average is 15-20 mph. The catch last night numbered Perognathus (formosus + penicillatus ?) Dipodomys merriami Peromyscus eremicus Onychomys torridus (tossed due to extensive damage by ants) Today 4 Ammospermophilus leucurus ((tossed, due to flea damage).

Of 40 traps (16 large Shermans, 5 small, 25 snap traps), caught 8 Dipodomys merriami, 1 Peromyscus eremicus, 4 Perognathus sp.. Most of the traps were not sprung. Ants are a problem here -- nearly half the line traps had ants and ~6 or 7 snap traps had their peanut butter removed by ants. Still, >25% success isn't too bad. 11am After stuffing 3 merriami's, I'm ready to pack up. This isn't baileyi country so I'm heading north & west to around Banner.

Lots of thorns on those bushers. Set 3 lines - one starting north from County Road 52, up a small canyon (100-150 meters long) and onto a sloping bench (~3° southerly slope). A second line began 20 meters to the [illegible] east, up another canyon, parallel to the first. The line continues north up through the canyon & along the escarpment forming the east edge of the bench. A deep wash (5-7m.) cuts the bench. A third line starts ~300m. East of the first 2, running north along a boulder strewn hillside. Granite. A few traps were also set in the wash at the base of their rocky hillside. In all three lines, large & small live traps were alternated with museum specials. Trap to trap distance was 15-25 meters. With a little luck I'll catch some of those Perognathus baileyi The vegetation over all three lines is typical of high-desert habitat. Spanish bayonet, various cacti (mainly opuntia), yuccas, and aromatic shrubs (none of whose names I know) form a cover of 50-75% in most places. Ipm just finished setting the traps - The coyotes

P. Brylski 1987 Journal 24 march 1 km NW Hwy 78 on County Road 52, San Diego Co., California have already begun to howl. One began a chorus an hour before dusk. Now at dusk I hear a group of 5-7 in the canyon north of here (500-1000 ft. distant) Several lone individuals respond from the surrounding hills. The temperature has dropped quite low probably ~15°C. The wind is blowing strongly, 20-30 mph, from the north down through "the narrows". 25 march. 6:30am Wind is still blowing @ 20-30mph from the north. The temperature dropped close to freezing last night. Several of my captive Perognathus were in poor shape after last night (although they were in the car). Rain clouds are blowing in - it's imminent that a downpour will begin soon. 1:30 p.m. Picked up the trap lines - still dry but the first drops have started falling. Captured 14 animals - two of which (P. eremicus) were released. One was in poor shape in the line trap and the second was a female which lasted out the night, its tail caught in a snap trap. Its tail was nearly severed at the base and had the line not been tied down, it surely would have gone a ways with the trap. With such endurance, I considered this animal an asset to the population (charmer). Caught a neotoma in a snap trap - a bit of a fluke. Also captured a number of Perognathus (fallax + possible baileyi) & P. eremicus. 8am depart for Orange County.

Vegetation includes Chrysothamnus, Yucca brevifolia, Sclazaria some Cholla cactus, some Atriplex. Numerous but not abundant wildflowers. Ground cover is fairly uniform -- roughly 30-40%. Granitic deposits form the N end of the valley which stretches perhaps 2-2 1/2 km. We are situated 1/2 down the valley.

My companion and assistant on this trip, Linda Clark, was there. We left Santa Cruz round 4 pm, headed south on 1, east on 129, south on 25, and south on County Road J1. We searched for an hour or so along J1 for a suitable trapping site. The problem is one of limited access into these hills. The roads to all ranches are blocked by locked gates. Several owners I approached denied access to us. Fire danger. General unfriendliness to strangers. Finally we settled upon this site - the McCullough Brothers property - posted with no trespassing signs of their names. We trespassed else we would not have left with any animals. The site here is hilly, slopes commonly 15-40°. Typically the canyons are grassland, upon which graze horse & cattle. Up from the grassland [annual], 6-18" tall but occasionally stubble due to recent harvest or heavy grazing) are oaks of unknown species (live oak anyway), digger pine, chaparral scrub - Eriogonum, chamise (Artemisia), and on the hill tops, Juniper trees.

P Brylski 1981 Journal 5 mi E, 1 mi S Hwy 58 and Shell Creek Rd., Los Padre Nat'l Forest San Luis Obispo Co., Calif Elev. 2000 ft 29 July 4:50 pm arrived at Los Padres Nat'l Forest, its NE edge. Followed the signs off just off Hwy 58 for Navajo Flat Campground etc. We're not staying at the regular campground - just beneath some bigger pines a couple several miles in from 58. After setting my camp we set out to lay traps. 7:50 pm we've set all the traps we're going to. 55 Shermans (5 mi use of live animals), Museum specials = 7 Lewis 10, 1 q 15 traps, 1 q 20 traps, 1 q 30 traps = 8/5 snap traps. = 150 traps total. Habitats are mainly chaparral scrub - chamise, several common mints, and an unidentified shrubby plant 2m tall w/ opposite leaves, small & oval. This shrub was co-dominant with chamise over much of its occurrence. One area spanning several hills and intervening "valleys" was comprised of "old growth" chamise - 70% cover, 2-3 m tall & individual bushes spaced at 3-5 m distance forming continuous habitat over much of this NE part of Los Padres Nat'l Forest. Soil here is gravelly & very easily burrowed by rodents - as evidenced by the density of burrows. Can't take more than several steps without intersecting a rodent burrow. Ground squirrels, heteromyids, Peromyscus - those are all fairly common here it seems. A second [illegible] this first habitat received 40 Shermans & 25 museum specials. The chamise habitat contained within its bounds several grassy openings - acre or two in area. Annual grass,

P. Brylski 1987 Journal 5 mi E [illegible] 1 mi S of Hwy 58 and Shell Creek Rd. Los Padres Nat'l Forest, San Luis Obispo Co., Calif Elev. 2000 ft 24 July moderately grazed by cattle, being 4-16" tall. Sherman live traps were placed in these areas. Just adjacent to the [illegible] habitat was a hillside covered of younger and sparser chanise w/ many forbs — mainly a mint in 2 m tall. 15 museum specials were set here. The third main area was a relatively recently burned over hillside of chanise. New growth has reached upwards of 1'½ m. but the charred branches of the old chanise remain. Cover here is ~ 30%. Soil is gravelly & friable. Rodent activity [illegible] is extremely high burrows everywhere. 15 Sheremans, 40 museum specials were set here. Fair amt of carnivore sign here also — mainly in badger & fox dens but various scat as well. No gopher traps were set though late in the evening we saw some fresh mounds. Gopher activity was also noted on the trap areas. These areas show good promise for good trap success. 11 pm sitting in camp listening to the screech owls & drinking wine. We lost another Dipos to heat exhaustion today; we had watered down the 3 mi jars & it was one of these that died. The Dipo's Perognathus in the Sherman traps are doing fine — showing little sign of heat stress. Moon is new. No wind. Temperature is rather low for this season — 18 °C. 30 July [illegible] check traps, 12 pm. Checked all the traps. Results were rather disappointing. 31 captures. 19 Peromyscus maniculatus, 1 P.thunei, 1 Microtus californicus (caught in

S. Brylski 1987 Journal of 5 mi E. Shell Creek Rd on Hwy 5F, 1 mi S. into Los Padres Nat'l Forest, San Luis Obispo Co., Calif Elev. 2000 ft 30 July Small draw vegetated by poison oak, grasses (-/ fern & of runways), 5 Perognathus californicus (2 of which were found in 1 live trap), 5 Dipodomys one of which was snap-trapped, the rest live trapped. About 65% of the museum specials on the transects over the turned-over chamise habitat were springy. These traps are simply too small to hold the Dipo's. One was captured in a snap trap but it was caught just on the neck - and still the trap was moved some distance. P. maniculatus were common on the recently turned-over chamise hill. The single trice was caught in the "old growth" dense chamise, as were many maniculatus. Nearly all the animals were pickled in formalin - 2 Dipo's & 2 Perognathus were kept alive. We'll transpport them in the Shermans since yesterday's experience suggests this is easier on them than the glass jars. 1 pm Depart for points West probably Hunter-Liggett Reserve or thereabouts. Also should note that single maniculatus was found bearing embryos. The 3 Dipo's I opened up were SS & hence F reprod. Stages here now are unknown. 240 ~16 mi N. Jolon, Fort Hunter Liggett along County Rd 418' Monterey Co., Calif Elev. 2200' 30 July 145 Just finished setting trap lines in chaparral-oak woodland habitat.

P. Brylski 1987 Journal ~16 mi. N. Jolon along County Rd G14, Fort Hunter Liggett, Monterey Co., Calif Elev. 2200' 30 July The road maps show the Jolon grade connecting Jolon and King City on County rd 14. We learned from a horse rancher that the road doesn't connect - it washed out several years back & hasn't been rebuilt. So we decided to find a suitable spot on the fort & take our chances. We settled on a camp at Milpitas Reservoir, a water hole used for fishing (also called Hunter- Liggett to Fishing Hole) & set traps in the chaparral to the east a mile or so. To get here take County Rd G,14 N. from Jolon . It becomes an earth road eventually and is then called Mission Creek Rd. Take this to Milpitas Rd & follow the turnoff for Milpitas Reservoir. From the reservoir follow the road (earth still) 1-mi or so east. Our dens are set in the chaparral just north of the road. The area here is quite pleasant. Short (grayed) annual grassland in the valley floors dotted by individual oaks. Moving upslope from the floor to continuous oak woodland covering gentle 5-15° slopes & some digger pine, alove the oak woodland, on the hilltops & steeper (10-35°) slopes is chamise. The chamise is well-developed: 2-3 m tall, in many places forming very dense thickets. Fire roads (GI maneuver access Rds?) provide convenient access to the chamise habitat interior. This chaparral habitat is quite extensive here. Goes on for miles. Soils are compacted w/ some organic content lower in elevation but gravelly, rocky, or sandy higher ups. Lark, scrub-jays

P. Brylska 1981 Journal ~16 mi N. Jolon along county Rd. G 18, Fort Hunter-Liggett, Monterey C., Calif Elev. 2200' Ground squirrels, acorn woodpeckers are common here. Bobcat scat was found on the fire roads but didn't see any coyote scat. 55 live traps & 50 snap traps were set in the chaparral habitat. 31 July 1am Start checking traps. 12 pm Park at Hunter-Liggett Fishing Pond. Captures are as follows: Neotoma fuscipes 3 Peromyscus maniculatus: 6 P. truei 10 Perognathus californicus 3 Peromyscus californicus 3 Dipodomys 6 ------- 31 Trap success was therefore quite high, considering that 15 snap traps were sprung w/o captures. One Dipos & one adult Neotoma were caught in the snap trap lines. In both cases, the animals were caught behind the neck. The Dipos was still alive when I found it this a.m. The sprung museum specials are mostly attributed to These two species. Everything save the live trapped Dipo's & Perognathus were pickled. One P. truei was found to have embryos (see catalogue # 333). The live Dipos will be sexed & either pickled or kept alive when we arrive in Berkeley. 1 pm after a swim in Milpitas Reservoir, leave for Berkeley.

Brylsko 1987 Journal ~2 km west Highway 86 (Salton City) on County Road 522, Imperial Co., California. 22 March 8 am. Drove here last night from the coast via Hwy 78, arriving fairly late. Moon was full, rising from the SE round 9 pm. Little or no wind. Upon arrival, I set 4 trap lines. 15 museum specials were set East & West of the spur road just off S22. 10 Shermans (large) were set ~20 m. North of these. Habitat is slightly sloping (~1-2°) flood plain; sandy soil w/ small rocks; vegetation is sparse (~7-10% cover) composed mainly of [illegible] & Larrea. "Scrub" describes it fairly well. 5 more museum specials & 5 small live traps were set in on the north side S22 where the terrain is rockier, slopes slightly more (4-5°), & thus supports denser scrub. Larrea there is co-dominant. 3 line traps were set in a steep wash (~3 m. across, 2 m. deep). D. deserti activity is evident south of S22 and to a lesser extent north of S22 as well. 9 am checked the line - no captures. South of S22, nearly all snap-traps were sprung & bait gone. At end of the line was a fresh fox scat & urine was found on one live trap. None of the live traps were [illegible] sprung. North of S22, 2 of 5

B. Brylski 1981 Journal Corral Hollow. 3 Aug. 6:15 am Rob't Seib & I leave Berkeley in my trust vw long. 7:40 am Arrive at Castle Rock after driving Mines & Tesla Rbs for snakes. Set out 60 Sherman live traps w/ rolled oats bait. Moon is 1/4, night temperature round 70 F, wind is 15 or so mph from north. 4 Aug. 1am leave Berkeley for Corral Hollow. 8am arrive on site. First line of 20 shermans is along north slope and base of Castle Rock. Grass is annual, 100% cover, 4-8" tall. Some rocks but mainly sloping grassland. No captures, no sprung traps. 2nd line runs along entrance Rd, just opposite Castle Rock (on E side of rd.), up into the rocky cyn - the only prominent one to the east of Castle Rock. Grassland, some chaparral scrub in the draw. The 2nd line of 20 - ups the canyon & above mi hill top grassland E to the escarpment yielded 1 Perognathus californius, 1 Dip's heermanni, 1 Reithrodontomys, 1 Peromyscus maniculatus. The kangaroo rat & pocket mouse were captured in the rocky scrub habitat which is found in the canyon floor 1/2 or so up the canyon. The trap success in the open grassland was dismal - despite apparently good burrowing conditions & full vegetative cover (grasses /forbs). The 3rd line of 20 sherman in rolling open grassland starting at the escarpment, in direction of Castle Rock, yielded nothing. 10am leave Corral Hollow for Berkeley.

P. Brulska 1981 Journal 10 mi. W. Benton Hot Springs along Hwy 120 Mono Co., Calif. 3 Sept. The soil is sandy to fine gravel. Most of the rabbitbrush is in bloom -- this species forms about 1/2 the # species (the dominant scrubs that is) + contributes round half the 50% ground cover. In a lower ponde wash to the north the Artemesia reaches several meters height and appears to be "old-growth". No or few rocks. Gayophytum -- that wispy ground cover wildflower -- is fairly dense on an easterly slope a hundred feet or so above these flats. Cow pies everywhere. Eutamias minimus quite common. Leprus, Sylvilagus found in taller Artemesia stand. I set 100 traps this afternoon -- 80 Shermans baited up oats, seeds and 20 museum species baited up fl- wutter-grain mix. The traps were set in 4 lines radiating out from the stock tank. N, NE, E, SE. 10pm Checked some of the lines -- those that I could find in the dark (quarter moon left us round now). Lots of Perognysus merio-latus, clearly 2 several age classes. All were removed -- 8 were picked, 9 were discarded (my object is to maximize Dipodomys, microdiprodys) Pair of shunt eared owls visited my camp. One flew over me repeatedly, several feet above my head, seemed upset.

P. Brylski Journal 10 mi. W. Benton Hot Springs along Hwy 120 Mono Co., Calif. 3 Sept. 8:30 am left Josy Lang's house in Sacramento w/ the intention of trapping heteromyids in Mono Co. Same night. Between the traffic in S. Lake Tahoe and my car's snail pace through the mountains, I hit Benton Hot Springs a bit later than expected ~ 5 pm. Route of travel was Hwy 50 -> Tahoe -> Pony Express Hwy to 395, -> Hwy 120 East -> Benton. At this locality I noted favorable habitat -- and the Chrysothamnus is blooming here. But I drove to Benton H.S. hoping for even better conditions near the megacephalus gilsonius type locality (2 mi S. Benton Station). Didn't make it that far before I decided this was the best place to trap, to the east several miles are alkali sinks -- Antelope Lake being one of them. Unfortunately I couldn't drive out that far on the earth road -- the soils here are very sandy to gravelly. My VW would not have made it. Instead I'm camped at the stock tank in the section noted above. Habitat is sagebrush - rabbitbrush scrub. Plant height is ~ 40-50 cm, quite uniform in height, density and species composition over much of the area. The terrain slopes gently to the east, to the edge of the alkali flats, where a low chain of hills rise several thousand feet above the flats

Journal 10 mi. W. Benton Hot Springs along Hwy 120 Mono Co., Calif. 4 Sept. 7am checked my line - several Dips ordii, several D. panamintinus, several (3) M. megacephalus 15 more P. maniculatus - there's an aberrant looking maniculatus or two in these - bigger cars, quite different pelage. I've saved these to prepare study skins of. Also caught 5 or so Extenias minimus (See Catalogue for it's - only the maniculatus catch was greater than indicated by the catalogue. All heteromyids (same one panamintinus found in a trap last night) are alive still. After I set up camp tonight I may sacrifice some of these. 12 noon leave for next locality. Weather, by the way, is round 85° F; wind 10-20 mph from East. Quite pleasant. Last night the air temperature went down to round 45° F. 9pm Depart for points south Vicinity Coso Junction (Hwy 395 + ) Inyo Co., Calif 4 Sept. 7pm having arrived here so late means I'll need to work pretty quickly. A little car trouble and several necessary additional stops (e.g., a swim in the Owens River at Hwy 6) caused my lateness. 9pm Traplines of Shermans were set in 3 localities at this vicinity.

Habitat here is a triplex scrub (including assorted shrubby - thorny plants I know not) comprising atriplex converticlia, several sagos, Eriogonum inflatum, etc. The soil is Sandy to gravelly and desert mounds are in evidence throughout. P. longimambis, D. oeritami and no doubt several Perognus are here also. Ammospermophilus leucurus seen today here.

Journal Vicinity Coso Junction, Inyo Co., Calif Sept 5 locality information - Says one article in the L.A. Times: the desert is a dangerous place Apparently its dangerous to those who strike out across the desert without water. Probably also without much idea of where they are 12 midnight : Turn on Sept. 6. 6:30 am Start checking traps. 12 noon finished gicking up the 4 mi. E Coso Jct trapline and either checking or collecting the traps 1-1/2 mi. E. Coso Junction. Since I caught no deserts and only 4 Perognathus formosus, I decided to spend another night here. There will be neither at Walker Pass, my next locality. I caught a few deserts here in the summer of 1979 but even then they were sparse. The soil there is pondy & deep enough in few places perhaps. Didn't catch many P longimembris last night either. Strange - They were extremely common my last visit here. The following species were caught in the petriplex scrub on the flats (catalogue locality 1, 1/2 mi. E Coso Junction): Peromyscus maniculatus 2 (+4 released) 30 captures / 60 traps Onychomys torridus 3 Pipidromys merriami 15 (several escaped) D. microgus 5 (one miscatalogued merriami - to be corrected later) A. levamis 1

Peromyscus maniculatus (?) 1 P. crinitus 2 Perognathus longimembris 1 Bigelomys merriami 1 D. microps 1 Perognathus formosus 4/10 captures/18 traps Well over the Perognathus formosus were pickled in 10% formalin. This formosus locality has not yet been described. Very rocky hillside, west facing 10-15°; vegetation is sparser than previous locality, at 30% cover by several unidentified thorny shrubs, barrel cactus. Creosote comes in at lower edge of transect (and hill). Soil is very rocky - almost no exposed sand or gravel. Rocks range in size from boulder size to fist size, the latter in greatest abundance by far. 4pm Cruised into the hills east of this last locality for general reconnaissance, 6pm back at camp, having set the trap lines: one line of 25 a bit (1/4 mi.) to east of the last locality. Also set 35 traps in Atriplex scrub at selected sites to catch deserti. Likely deserti habitat was walked and 2-3 traps placed at every sandy spit w/ many burrows. The line

O. Brylesko 1981 Journal Vicinity Coso Junction, Inyo Co., Calif. 5 Sept Labelled (2) in the sketch was maintained - though trap number was reduced to 15 (from 20) with fire stations set at 2 traps. Transect (3) was abandoned and the traps [illegible] used for the "intensive desert search": All told, 71 traps - all Shermans - are set now. The remaining 9 hold live animals (Dipodomys, microtipes) from Mono Co. 10pm left early to check the trapline set in formosus habitat. 1020pm arrive at the line - but drat! my headlight batteries are run down. Pretty nice out here anyway - away from the 395 noise. Time to relax with a beer and a smoke. 6 Sept. 630am Another cloudless morning. 11am pulled in all of the traps - save one which appears to be missing. Unfortunately, only caught one deserti and one formosus in addition to the other species. Trap results as follows: Aeiglexperrob - panly flats transects (2) Peromyscus maniculatus 8 O. torridus 2 (live) 21 captures 45 traps Ammospermophilus leucurus 2 (in alcohol) D. deserti 1 (live) D. nevirami 9 (2 in alcohol) D. microps 4 [illegible] (2 in alcohol) The discrepancy between this list and the catalogue is because many were released - particular the P. manic and D. nevirami. Several microps escaped.

P. Brylski 1981 Journal Vicente Costa Junction, Inyo Co., Calif. (Sept cont'd) The rocky-scrub habitat yielded the following species: P. crinitus 10 (all released) Perognathus formosus 1 (live) P. longimembris 1 (in alcohol) D. merriami 3 (released) D. microps 2 ( " ) 17 captures/25 traps Again, most animals were fixed in 10% formalin. Since I've already captured a number of merriami's, (and Peromyscus), there were released. Also, since I need to break camp and head to Walker Pass, the fewer animals to groom, the better. My plan for catching deserti didn't work. They certainly aren't numerous here -- but there's certainly more than one. The sand isn't loose or deep enough (or both) here. The valley winds scour the flats leaving a fine pavement of sorts -- not the typical deserti pavement however. Weights & total body length of merriam k-rats are: 220/36.5; 250/39.5; 240/33.5; 250/34; 240/39.5; 215/34.5 235/35; 246/36; 245/36. The circled individuals are probably this year's juveniles. Apparently they reach adult weight prior to adult body length (?) We know that adult proportions are reached a month or so after parturition -- this places the event in early July or later. Wait! The first individual had a broken tail. The second may have escaped my notice

P. Brylski 1981 Journal Vicinity Coso Junction, Inyo Co., Calif 6 Sept (cont'd) It is equally plausible than that this year's young are indistinguishable in size from adults. This is plausible if breeding occurred in late may , parturition in late June (for example). At any rate , 6 of 8 ? merriani had scars of the two nulliparous FF, one was of adult size and the other greatly juvenile though its tail had been broken. None of the FF's had distended mammae. Presumably if juveniles have not yet been weaned , they are feeding on seeds etc in the burrow. Perhaps breeding wasn't carried through this year -- but this is unlikely since it would place 6 of 8 FF at ages over 1 1/2 yrs -- an unlikely life span for a majority of the FF, 2pm Leave camp (packed) for washup at the rest stop (Coso Rd. and Hwy 395) and then on to Walker Pass. 1 1/2 mi S; Walker Pass Kern Co., Calif 6 Sept 4pm Arrived here by Hwy 395 -> 14 -> Walker Pass, after late lunch, I turned east again on 14 and drove 1 1/2 mi. to an earth road trending south then west.

After distributing Shermans among the students, I was left with only 10 for myself. These were set by Maria Alicia and myself bordering the road (1.8 mi N. Chilcoot) All told, 80 Shermans were set and an undetermined # of Mussera specials. 5:30pm After setting the traps we caravanned up the slope and set up camp along side the stream (more of a sleep actually). Maria Alicia and I hiked over parts of the rocky hillsides in search of Neotoma sign. We found none and therefore set no traps among the rocks & boulders. 9:30pm dinner time. Incidentally, on our way down the slope in the vehicles, a Dipodomyss appeared on the road - running in front of the car (driven by R. Ostfeld). I gunned out & chased him down - The chase lasted some 4 minutes. Finally he crouched still in the shade of the car (it was twilight). As I snatched him rather briskly, I believe he died of shock. 13:00pm We checked the lines & released a considerable # of P. maniculatus. On my line were 2 Dipos; ordii 1 panamintinus. 4 P. manic- ulatus were released. The Dipos were left to be retrieved in the morning. 1:30 am Finally hitting the pack.

Bryski 1982 Journal 1.5 mi E Coso Jct, Inyo Co., Calif. 3480 ft. 8 March Man was I tired! Checked the trap lines this a.m. and still feeling exhausted, went back to bed. The catch wasn't particularly plentiful: 8 D. merriami, (5 catalogued, 3 released - total), 2 P. longimembris, 1 P. maniculatus (released). 3 merriami's were ♀ and all carried embryos. Still quite small - hardly large enough for crown-rump length measurement. The embryos were separated from their mothers and fixed in 10% formalin. The reproductive parts of the total likewise were separated and fixed in formalin. Several merriami's were preserved by vascular perfusion. The technique involves anesthetizing with Nembutal, purifying the system of blood w/ 0.9% saline injected into the heart followed by a formalin injection into the heart. After processing the animals (the vascular perfusion took ~25 min / specimen), another 90 traps were set bringing the total to 150. It's quite cold out tonight - round high 40°. Clear sky. Full moon which rose at dusk. Coyotes were heard tonight as were cattle - still on their range. 9 March Ran up to check the trap lines. Temperature last night dropped pretty low - high 30°/low 40°. 12pm All lines have been checked; some have been picked up, mainly those that two nights have been just in on.

However, two well developed sets were found -- one 25-mm CR, one 27. The ? of the 25-mm embryos died in the trap last night/this morning.. The 27 mm embryo were still alive and moving when I fixed them. The pattern established with today's yesterday's specimen is that more embryos implant than the number that develops fully. The larger embryos are usually in twins; earlier stage embryos usually number 3 or 4 per ?. One specimen (#489) showed evidence of embryo resorption -- the 4th being much smaller than the other 3. Apparently no longimembris ?? were captured -- though 9 ?'s were caught. Strange, 10 o'st murriani were released. No other species captured. 8pm Several more lines were set.

It's becoming clear how difficult it will be to get a full series of (replicated) embryos for D. merriami. Only 11 FF were captured today, out of 160 traps. A single D. microsp F was captured on line 8 (see map) in creosote scrub. She bore 3 embryos in intermediate stages of development. The remaining 10 F merriami's, all pregnant, are being saved in expectation of sacrificing them at later stages of embryonic devel- opment. 3 of the merriami and 3 formozus were caught at the locality north of here, on the west side of 395 (this locality on east side of 395). 6pm after moving 3 or 4 trap lines and setting 3 more, the trapping picture looks as follows.

Journal 10 March Vicinity of Coco Jet., Snyo Co., Calif. that a single ♀ Perognathus was captured from either locality, suggesting that the ♂♂ are in the burrows suckling youngsters. Longimembris estimates though I don't think formosus does. There ♀ the ♂ long. appear to be several though the formosus show a partial scrotal state with very full seminal vesicles. Perhaps there's sexual difference in emergence time from estivation. It does seem less unlikely that the females wouldn't emerge from the burrows to feed. The question awaits study & suppose. 10pm transferred the fixed embryos ♂ ♂ repro tracts from the 2 oz jar to quart jar after wrapping them individually in cheese cloth, icing them with the fingerling alcoholic trays. The truck is alive with the rattling of Dipos in their traps. Figured that if I could stockpile some 50-100 in early pregnancy (Survey showed that if ♀ was < 40g, more than likely the embryos were quite undeveloped), then I could sacrifice them at various times (1 week, 2 weeks, etc) for a pure representation of embryos at more advanced stages. 11 March I am up to check the traps.

14.4 mi E, 0.7 mi S. Olancha, Inyo Co., Calif 11 March 12 am Well, I started south & ended up north of Cosu Junction! I drove south on 395 to the Trona-Wildflower Road which leads north to Panamint Valley. Since it was raining more heavily as I travelled south, since I thought I could find desert habitat to the north, and since I wanted one more crack at the Coso Junction locality for merriami, I decided to change direction. Drove north on the Trona Rd up through the Panamint Valley. Just north of Trona there seemed to be some fine sandy areas, but not of great expanse. I assumed I'd find something in Panamint Valley. Nothing! all desert pavement. I wonder if merriami can even make it there! At 190 I turned west toward Lone Pine. and just before the 136 Jct, I found some dunes and associated 190 136 habitats of deserti-quality. Since marginal 190 records for deserti include Olancha and Keeler I was looking for former habitat which spawned those marginal records. Perhaps I found it. The map above shows the earth road bearing north and west off 190, 0.7 mi S of Hwy 136-190 Jct. The dunes stretch for a mere ½ mile but drifted sand gleans to surround the area. I saw several merriami on the road, but this is no surprise. I set 115 traps after dark - hope I can find them all. After setting the traps I buzzed into Olancha for a good old

Flash Flood warnings were out for the desert. Definitely a jeopardy to this fledgling research project. The weather today was quite civil, mid 60s in temperature. 10-20mph winds, billowy cumulus clouds. White one. Tonight, the sky is clear, giving view to bright stars in the moonless sky. 9:30pm checked one line and brought in 4 ff (released 4 of them); no other captures. Three ff showed embryos, but very early in development: PVB 539,540 probably mated earlier this week. PVB 541 appears to be 7-14 days pregnant. #542 showed an abnormal growth on the kidney. Concernous? Temperature at 10pm is 6°C. 20 March 12noon Pulled up all 7 line traps. What a catch! All merriami individuals were sexed on the spot and most all fff released.

Oddly enough, not a single other species was captured. A few lepus californicus were seen. The area clearly shows signs of a recent storm - standing water in puddle in few places; moist/damp ground. Perhaps the storm kept all good merriami underground & my bait was especially alluring to them. 7.7 mi S, 3-mi W Kelso, Kelso Dunes, San Bernardino Co., Calif 20 March Arrived here round 1:30 pm after stopping out the area. This site lies along the public access route to the dunes and doubles in this vicinity as an airstrip. Day-hikers are common here, and as such is a problem: potential loss of traps, many questions, etc. I'm just west of the dunes. Creosote flats 100-200 meters deep separate me from the dunes. Grasses grow in tussocks around the rolling hills (sand) at the base of the big dune.

Still 1/2 mi or so short of the dune peaks. Traps set at 15-20 m distances to maximize deserti captures.

One ♀ showed signs of reproduction — swollen uteri [illegible] o-ovaries -uteri in a configuration I recognize from pregnant adult merriami. 2:30 pm Set 14 gopher live traps at Rose Valley Ranch. Mucha pocket gophers there. 4:30 pm Still processing rodents. So far the embryos are averaging 12-14 mm CR. 5:30 Checked gopher traps at Rose Valley Ranch several miles north of here. No success. Those gopher live-traps are not easy to set out. 11 pm Just finished a few more rodents. Checked the ♀♀ & captured 10-11 March 1982. After return the four ♀ checked all suffered marked weight loss and had resorbed the embryos. Since they had appeared to be doing the same thing in Soving a week ago, I decided to release them. I caught them like of course. Finally, since the embryos are still a bit small, I'll leave tomorrow, taking a handful of ♀♀ of me; this time I'll give them lettuce ad libido as opposed to every few days.

Journal 0.5 mi S Benton Station, Mono Co., Calif 23 March Arrived this locality round 4 pm after driving up from Coso Junction ( Hwy 395 -> C -> Benton Sta). Type locality for m. megaphelus polionus is 2 mi S Benton Station, but it'll be damned if there's either a ranch there or suitable k-mouse habitat. Grinnell lists it as McKeever's Ranch, and Hafner calls it Taylor Ranch. Nobody heard of Taylor around here. Since BLM land is mostly east of Hwy 6, and since my first choice (west of Hwy 6) was disputed by a very unfriendly redneck (not the landowner), I've decided to trap on BLM land. Habitat is seagebrush scrub, round 2-3 ft tall, dominated by antenoxia and with various thorny shrubs. Some cholla cactus. West facing slope round 5-8°, sandy to gravelly-sandy soil. Plant cover is round 30-60% (it varies, tending toward the latter). Heteromyid burrows are abundant. Set 1 line of 40 traps from the Hwy east, one line of 30 a bit north (all roughly same locality) and 2 more lines, both 20 yards Sherman's near the 30-trap line (traps were spaced 15 m within a line and lines were from 20 to 60 m apart). 7:30 pm went into Benton for some dinner. Cafe's open but kitchen's closed. I bought one glass of wine and the rest were bought by locals. 10:30 pm stagger out of Benton. Nice folks, but they drink alot.

P. Brylski 1982 Journal 0.5 mi S Benton Station, Inyo Co., Calif 24 March Farm check the traps and pick them up. Two microlipodops!! Elevation here's around 5300 ft and snow's still found in pockets (rare though). Daytime temperature was ~70°F and nighttime round 35°F. Still, either K-mice don't occur on this plot or they're still in winter estivation. I suspect the latter. Only caught on P. parvus, a nullip. ♀. She died in the trap. Probably she was among the first of her kind above ground after the winter. Can't say for sure of course. Also caught D. neviansi, and probable D. ordii [illegible] and what appears to be D. panamintius. All ♀ These latter 3 were kept in the Shermons, supplemented w/ sand, lettuce and feed. Haven't time to really look them over since I'm heading south again. Three neviansi ♀♀ of which I sacrificed and examined showed little/no sign of pregnancy. Perhaps very early. All panamintius were non-scrotal. Those 8 kept. Therefore, reproduction is not underway here for the heteromyids. Though I did release D. maniculatus (30♂♀, 1♀), one ♀ which I sacrificed showed well-developed embryos. This contrasts with the Coso Mt maniculatus which gave birth before my visit on 10-11 March 1982. The 2000 ft difference in elevation has quite a marked effect. 1230pm load up and head south.

Just south of the 395-190 Junction turn east (immediately N. of Cottonwood Cafe) and drive for a mile or so. The dunes mainly Start north of the dirt road. Good access. Wonderful deserti habitat. Or so I suspect. Set 80 Sherman's in 3 lines in the dunes. Plenty of entrapped dune habitat left - particularly in the central dunes area and the eastern dunes area. Also, the dunes extend east (south of 190) all the way to the 190-136 Jct. (see 11-12 March 1982). 4pm head south to set 2 more sets of traps - one at Rose Valley Ranch for pocket gophers and one along the aqueduct scree for P. formosus. 5:30 pm Finished setting the pocket gopher traps. Set 10 live traps and 9 macabees, usually in tandem. 2.7 mi N. Coso Junction, Inyo Co., Calif 5:30pm arrived here (turn west at Dunmore and take earth road to the aqueduct) and met Phil Hennis, part owner of the Rose Valley Ranch. We talked for some 45 minutes about pocket gophers, government (Fish & Game, BLM), and the contract I worked on out here 3 summers ago. Stayed in a trailer home on the Rose Valley Ranch in fact.

The 3 lines were at: (1) Olancha (in the desert, for) D. deserti (2) Calif. aqueduct for P. formosus and (3) at Rose Valley Ranch for T. bottae . The Rose Valley Ranch yielded four dead gophers. None in the live traps. Three were pregnant though one ? adult had given birth within the last few days. The others were all ??, 2 subadult and one juvenile. I didn't keep any, since they were neither alive (for J.L. Patton) nor pregnant (forme). The aqueduct yielded, of 30 traps, 5 ? P. formosus , 1 ? P. formosus (PVB 587), a late pregnant ? merriami, 3 P. maniculatus . The Olancha front resulted in very few deserti captures: a single ? and 2 ??

The winds were so great (30-50 mph) that I gave up and took the opportunity to get some more holding cages. I returned here after 2 nights and one day in Berkeley with 50 mouse cages. I drove straight for 10 hours from Berkeley here, to pick up some pregnant meriari. Also brought a ? meriari (collected by RL Seib) which had a litter of two young in the cage at Berkeley.

I flagged two such burrows located under creosote bushes and returned later to shovel. In neither case could I find the ? or her young. Perhaps these were "cache burrows" and after leaving she emerged and returned to a "natal burrow". Or perhaps she flagged the burrow beneath the surface and eluded me. Better luck next time. In digging out these burrows I found the creosote root systems to be very shallow - I had hoped to find a nest chamber amidst these roots. The burrows must head down some distance -- perhaps several feet. 220pm leave for Kelso. Oh yes! Found a desert tortoise 2 mi S Kelso, San Bernardino Co., Calif 3 April.

Had gone there to find creosote habitat but was largely unsuccessful. 40 desert had been taken at Mecca in 1908 (see MVZ catalogue) but the area now is 100% agriculture. And the wind was blowing 75+ mph. So today I've been working the alfalfa fields for live Thomomys. Caught 5 so far around the ranch-house. Smart little devils. Am using J.L Patton's lim-traps.

The Neotoma's are like big P. californicus. The Perognathus seem to be in full swing reproductively, or perhaps slightly past. Several ζ formosus were nursing young and one had late-term fetuses. One longimembri had early embryos, one was peak estrus and a third was nursing young. Strange, particularly since I've been monitoring this site for over a month. Not a single ζ longimembri captured before today as I recall. I guess they're simply been avoiding the traps. -- but why not the others? (caught plenty of them). I think they bred early, then continued to estivate. In any case, the prospects for getting a high volume of material for perognathus are now slim. There are several positive news items. First, the desert ζ which delivered young continues to care for the remaining 2. The second is that a ζ battal delivered young today in a small 'mouse holding cage'. This occurred round 1230-1 pm since when I looked at her at feeding time she was still ripping placenta and the blood was fresh. Moreover when I first looked

P.U.Brylski 1982 Journal 2.5 mi N Coso Jct., Inyo Co., Calif. 18 April There were 3 young and 10 min later there were #3 (I had taken one immediately for fixation). There was almost nothing in the cage to obstruct my vision, so the counts are reliable. Despite my disturbances, such as an attempt (unsuccessful) to put in a small milk carton for a nest box, she continues to care for them I think. They still squeal periodically 8 hours after delivery. Healthy squeals. She runs all over them as she courses through the box. I added more alfalfa and she has made a burrow beneath it and moved the young there. Spill, how long she will care for them I don't know. I'm keeping an attentive ear to the cave to get the dead babies in the event she finally abandons them. I set 120 traps just west of Coso Jct along the aqueduct and in the creosote flats. This makes 200 Sherman set tonight. trav lines Rose Valley Ranch, 2.5 mi N Coso Jct Coso Rest Area Highway 395 Cair Aqueduct Also, about 10 gopher live traps are set at the Rose Valley Ranch. 19 April 1230 pm Traps are checked and I'm here at Rose Valley Ranch checking gopher traps and processing specimens.

The signs point to formosus θθ as largely having given birth. The θθ caught (4) seem to support this. Pregnant formosus are likely to be over 30 g at this point. The pregnant longimembris are around 10 g. Finally, a single bottae was captured today and the traps removed.

P. Brylski 1982 Journal 1.6 mi N Chilcot, Plumas Co., California 20 May 2:30pm After leaving Berkeley yesterday round 11:30 am I drove here via Truckee, Loyalton and Vinton arriving roughly 4:30 pm. The truck lost a front tire enroute. 150 Sherman were set in the Sagebrush scrub around the stated locality. The very sandy habitat just north of the entrance to the Ranch (on the west side of the highway) was particularly good for microdipodops megacephalus. Deep sand covered up Artemisia tridentata is to be found on either side of the road but is most extensive to the east of the highway. 80 traps were set here and another 70 were set off the earth road as shown on the map. 45' tall Jeffrey Pine / / / = locations of trap lines. earth road cattle guard Chilcot -- Highway 49 --> Baker Reno <- Loyalton Temperature last night was in the low 40° F.

P. Brylski 1982 Journal 1.6 mi N. Chilcoot, Plumas Co., Calif. 20 may The microdips have apparently just begun to enter breeding condition. No signs of estrus were observed but several ♀♀ had enlarged moderately to very swollen uteri — apparently in preparation for implantation. The ♂♂ were not scrotal however, though the seminal vesicles were fairly large (~ 16 mm). The situation was similar with the Perognathus, perhaps ♀♀ showing even less reproductive readiness though ♂ parvus were mostly semi-scrotal with full seminal vesicles. A single ♀ D. ordii was in peak estrus. Several maniculata ♀♀ were obviously pregnant. Repro tracts from parvus and megaphorus were saved; formalin-fixed animals were prepared first of vascular perfusion (VP on tags / notes). Six maniculata were kept live for breeding experiments — one was in v. late term pregnant. She can barely move. two ♂ ordii were saved live for breeding also. I'm a bit surprised to see the kangaroo and pocket mice w/o embryos. The Artemisia are well into their new growth. growth. Forbs are common now — many in bloom. The greens have set seed. Perhaps this is a result of the late spring (it snowed 6" up here 3 weeks ago), though it may also be the normal state of affairs. 22 may 10 mi E, 0.2 mi S Mono City (Jct 395 & 167), Mono Co., Calif.

Journal 16 mi E, 0.2 mi's Mono City, (Jct 395 + 167), Mono Co., Calif 6475ft 22 May cont'd of this locality. Luckily I remembered his directions, simple as they were. An earth road cuts south from 167 almost exactly 10 mi E of the 395 + 167 Jct. This road heads straight for Mono Lake, which lies about 2 mi (or so) south of 167 at this point. The road cuts through a number of dunes, all vegetated by Chrysanthemum (I think) and Artemesia. Junipers spill over from the hills to the north. The dunes are intermittent, separated by dense flats of Artemesin (i.e mul-caked soil) and small rifts of shallow to moderately deep sand. The dunes themselves, rising only 10-30 ft above the rifts are quite fine - sparse vegetation. Fine sand. Mucho sign of Lagus californicus and a Sylvilegus. I set ~~90 Shawmans last night w/ little expectation of finding pregnant Microdiplopops pallidus. Yet the night was surprisingly warm (it's now 60°F; last night it dropped to round 50°F). Captures were as follows: B. maniculatus 4 Etonicus meridiani 1 Phyo. ordei 1♂ 2♀ (one lost, the other peak extras) M. pallidus 2♂ 3♀ → 2♀, 1♂ catalogued Dipo paramenter 1♂ 14 Not particularly good trap success, but 2/3 of yielded embryo sets (cf 12,20). No f paras caught. 3 trap lines moved today because of poor success and 90 more traps were set out

Journal 10 mi E, 0.2 mi S Mono City (Jet 395+167), Mono Co., Calif. 6475 ft 22 May at this general vicinity. Total now is 180 traps. 23 May 1230 pm Checked the trap lines and catalogued 8 specimens. Trap results are as follows: Peromyscus maniculatus 5 (released) Eutamias minimus 2 (embryo set, a ♀ dead in trap catalogued), Pereigathus parvus 1 ♂ 1 ♀ (♀ catalogued) M. pallidus 5 ♂ 6 ♀ (one escape; one uncatalogued, ♀ catalogued) 19 No Dipodomys caught today. The lines are located in sparse (10% cover) to moderate (30-40%) cover Artemisia and Chrysothamnus vegetation. Mostly these plants are < 1.5 m tall. On the edges of the dunes which rise 5-10 m. above the flats the vegetation is closer and taller. Microdipodops seem equally scarce in all habitats. Several lines of 20 yielded no animals of any taxon. A number of times, though, I noted what appeared to be microdipodops tracks (tail marks, bathing sign) in front of the traps but no animals caught in any nearby traps. Also, this sign didn't seem to correlate w/ any habitat quality. Persnickety animals I guess. 5/6 ♀♀ were pregnant (including the escapee). One may have been in early pregnancy, though I doubt it. Most of my meager trap success was on the last 2 lines and were it not for this I would have moved camp toward Hawthorne, town of which is the type locality of M. p. pallidus.

A ♀ was released also, clearly having given birth recently. The weather continues to be idyllic (sp?), days in the [illegible] mid 80s, nights in hi 40s - lo 50s. Little wind. No moon. 25 may Captures today were as follows: C. minimus 7 P. moniolatus 5 M. pallidus 6 ♂ 4 ♀ P. parvus 1 ♂ 2 ♀ pallidus showed signs of recent parturition so were released. Captures have not been particularly good and IVB 702 a ♀ pallidus delivered last night and rejected the young. Another ♀ pallidus, # 701 showed a 2 or 3 g wt loss, clearly showing embryo resorption. I've decided to take the 3 ♀ pallidus showing late pregnancy - I leave for Berkeley. If I get them grown enough on a diet of crickets etc away and the warm undisturbed environment of my animal room may save the embryos.

Brylock 1982 Journal 1.6 mi N. Anilcort, Plumas Co., Calif. 14 June Arrived here around 4:30 pm after driving all afternoon from Berkeley (left ~ 11 am). Same locality as before. This time there is much in bloom. The lupine, Truncus (a few trees around the campsite), various wild flowers. Round a foot of new shoots to the Antemaria. The grasses have set seed and form a uniform cover over much of the desert floor — particularly in the area of antemaria cover >50%. Of course, in the dune areas just east of the highway there is little cover. Daytime temperatures are in the 70s w/ occasional high cumulus clouds. Raindrop marks in the sand attest to a recent sprinkle. Set 196 traps, roughly equally split between roadside dunes and antemaria flats and the sloping Antemaria flats east of the highway (below the large Jeffrey pine) 15 June Captures this morning are as follows: Perognathus parvus ♂ 6 ♀ 5 D. ordii ·2 2 R. panaminticus 7 7 M. megacephalus 4 #5 P. minutulus 10 (total) E. minimus 8 S. heldingi 1 56 / 96 The kangaroo mice have largely dropped young.

P. Brylska 1982 Journal 1.6 ~ N Cluncoat, Plumas Co., Calif 15 June (cont'd.) was especially distended - usually the left. (3/4) A moderate number of parvus embryo sets was obtained (4) and a late-pregnant ♀ was caged. Also, a pregnant (early) ordii was captured - certainly a youngster of this year. And two late pregnant janamint k-rats (one catalogued, one caged). Single number of male repro tracts were taken for the gametogenesis study. Otherwise, not much to note (damn megacephalus!!) A few days earlier would likely have made a difference on some of those ♀ megacephalus. Several seem to be quite new mothers, judging from the degree of triple distension. The lines were rebooted at 5pm and the 19 trays removed were set in a new line.

P. Brylski 1982 Journal San Jose, Costa Rica (Hotel Galileo, Avenida Centrale y Calle 13) 14 July. 330 pm Pete Rogers, El Heke and 8 arrived here last night round 11pm. Taking a minibus cab from the airport, we tried to find room at (Calle Nueva y Avenida Nueva y [illegible]) a hotel recommended by M. Hagner. Ended up here. Today we ran errands to the permit office, liquid nitrogen store (Industriales Ligerido), Farmacias (por formalin & cotton). All in all, a successful day - the permits will be ready tomorrow as will a gallon of 40% formalin (at 532 colons/gal.). Walking around San Jose & taking cabs to the University etc. has been a fine introduction to the people here. Lots of them. Young age structure - vast median age seems to be 20-25 yrs. Many uncleaned children. The people are friendly - there's much eye contact, particularly from the younger people, and smiles come easily. Datsun & Mitsubishi seem to be having a field day here. Most cars are made by them. The weather is tolerable - alternating between sunny & hot of moderate humidity and cool breezy overcast skies. Many carry portable umbrellas. We stopped by the University of Costa Rica

Journal 22 km E (by tmz) Trinidad de Doto, San Jose Province, Costa Rica 2600 m. 18 July The Scotinomys here are presumably teguina (Alston's brown mouse), the Reithrodontomys of this region include simichrasti (an abundance of black dorsally which largely obscures the cinnamon ground color); braurostris (from the Cordillera Central of Costa Rica); mexicanus (usually arbor. of humid oak-pine forest but also occurs in rain forest ^) semi-arid deciduous forests). tail is unicolor * rarely white tipped; creper (upper parts tawny or cinnamon-orange heavily interspersed w/ black hairs^); tail unicolor [illegible] second & well-haired): The Oryzomys include: alforoi (195- Total L. color underparts tail alforoi 195-257- variable white fulvescens 168-235 buff->tawny white->luff dk brown pale brown caliginosus 196-240 russet->tawny paler but not sharply so devius 335-360 dark tawny most of the animals caught today were in the mature forest. I caught 27 Heteromys + a juvenile of the same species. A number of specimens were prepared as study skins, with tissue taken - these included midipes, several Reithrodontomys and an Oryzomys (probably alforoi). The Scotinomys, Oryzomys (large one - devius) and several Heteromys were saved for [illegible] in San Jose. One Heteromys f had v. distended mammal and was around peak estrus.

Journal 2.2km E (by way Z) Trinidad de Dota, San Jose Province Costa Rica 2600m 18 July caught Restroodontonyx - one specimen of 24,32. After preparing some specimens we drove west again forward San Jose , to trap around Tres Maria at a locality told us by M. Hafner. Cerros de la Carpintero 1450m 19 July 12noon we arrived here yesterday afternoon after driving on several dirt roads south of Tres Rios (South of Interamericana Hwy). Arrived in the driveway of Oscar Mora and his wife , at the end of the dirt road. Just below where a tunnel through the mtn is being dug. The terrain is mostly either straight up or straight down. Nearly vegetated of Lord knows what. Coffee plantations several to 10 hectares dot the hillsides. Dense thorny small trees, thick forb groundcover , larger dicots (trees) comprised the vegetation trapped. I set a line of 50 up the hill to the east of Oscar's modest home, through the thorn trees - up through the coffee plantation. To the top of the hill, vegetated of a moderate (50%) overstory of a broadleaf tree of dense understory of rosaceous lush , forbs etc. Another line of 40 was set in comparable habitat to the west & south of Oscar's home - up the road which leads to the top of the hills (1-1/2 mi away) where Hafner probably

Journal Cerros de la Carpintera, 2 km S (by road) San Diego Prov. San Jose, Costa Rica 1450 m 19 July trapped Heteronmys. Ed + Duke set traps in similar or the same habitats. of ~240 traps we caught 6 Scotinomy's teguina + 1 Orizomy's alfaro'. One Scotinomy's (PUB 741) yielded a single late term embryo and another (PUB 746) had a somewhat smaller embryo. 741 embryo was separately placed in formalin whereas the entire carcass of 746 was fluid-preserved. The Scotinomy's are diurnal - we heard them singing around the car this a.m. while we worked. Their jivkings last night (trap success that is) - perhaps because of the disturbed nature of the entire area. The whole canyon is inhabited by Costa Ricans - look somewhat like Daly City - row upon row of homes. Prefab. Oscar's home, however, was hand-made + sits up higher in the canyon. He slept in his 2nd room. Drank coffee w/ he + his wife last night and again w/ Oscar this morning.

San Jose, Costa Rica (Hotel Garden) 20 July little (or nothing) to report. Worked today in the lab at the UCR cellular & molecular biology department. Lunched w/ Tony Morena, Pedro Leone, the head of the department (name?) -I- Leone. 21 July Our rental VW was broken into last night. Cassette/radio, speakers & outside mirror are gone. After many errands (UCR, gas, Global Rental, Police Sta. [closed for lunch])— we are finally on our way. [illegible] 3 km NNE Las Cañas, Guanacaste Province, Costa Rica 150m 21 July 9am we drove all afternoon, arriving in Los Cañas round 3pm and later finding a suitable trapping locality. Using Genoways as a reference we settled on this site— on the N. side of the road; a patch (unknown area) of 2° growth overstory hardwood (<75 ft tall) & varying amounts of understory. Duke set some 50 traps on in the forest's edge while I set 40 in the forest. He set 60 traps up the road @ 8km NNE Los Cañas in shrub -2° growth. While setting traps I saw 3 howler monkeys (Alouatta p. palliata) – an adult σ and 2 smaller, one clearly a juvenile. They moved off after only several minutes of observation so there's little to say other than that. Duke Rogers also sighted a Poto (Poto flavus) in this same stand of trees.

Journal 3 km NNE Los Cañas, Guanacaste Province Costa Rica 150 m 21 July I set another line some 50 m. up to road and to the south (east) - this line of 30 being in 2nd growth of dense + low (<2m) herbaceous growth. Not knowing the tree species + being very busy setting the traps + watching for snakes, I failed to take note of the particular differences between the N + S sides of the road. They are different. In height (~ 75 vs 40 ft tall overstory, resp.) slope (10-50% N (vs) 5-10% N resp.), type of understory (thorny scrub - Rose (vs) dense ground vines, resp.) and species composition of the overstory. Later we joined Ed Hester + comped at the river crossing between 3 + 8 km NNE Los Cañas. Setting traps today was a bit uncomfortable in this humidity. Can't remember when I sweated so much. Nighttime temperatures were was comfortable ~65-70°F and the wind blew strongly. 22 July 11am collected our traps - total captures of 17 Liomys salvini nothing else. My line of 30 east of the tiny yielded nothing. Subcounts were Ed=3, Duke=7, Shid=7. After having breakfast in Tilaran we set ourselves to stuffing Liomys on the roadside

Journal 4.6 5.0 km E (by road) Tilaram, Guanacaste Province, Costa Rica 22 July 9 am ~ 250 traps were set at these two localities after much driving around. We eventually saw 2 sides of Lake Arenal - a beautiful natural lake further north of these localities. The 5.0 km locality overlooks Lake Arenal from the south. Both localities are 2° growth hardwood forest - the first being along a riparian habitat bounded by the bay and a farm. Here Ed & I saw two armadillos length about 1 foot (total). Whether there were Cabassous or Dasypus I knew not; neither are supposed to be diurnal - thought these were clearly juveniles. They disappeared down their burrows amidst thick riparian ground cover. For the next hour of setting traps in the forest paralleling the riparian area & saw considerable sign (burrows & smaller diggings probably the result of foraging) in the area. After setting 50 traps in this area, Duke & I drove E to N further yet some 6.9 km. Ed & I hiked then up the hill from here into dense 2° forest; I went down the hill (in the direction of the lake) into comparable 2° forest. Between worries of charging bulls (& crossed their pasture) & fer de lance, I was greatly distracted.

Journal 4.1 - 5.0 km E (byroad) Tilaran, Guanacaste Prov., Costa Rica 23 July Picked up trap lines, about 120 traps at each locality. Results were 19 or 20 Heteromys desmaresti- ianus and one Oryzomys alfaroi. I caught 6 or 7 heteromyss at 4.1 km E as in the riparian forest on the south side of the way. 4.1km x where El Neda fought 2 juvenile armadillos. 5.0km 2pm just outside of Tilaran we stopped to organize last night's catch. At least several of the Heteromyss are pregnant. I sacrificed 3 animals, 2f + a juvenile s? (PVB 759-761). Both ff were pregnant - one very late pregnant (34 mm embryos). 6 km S Iberia (by hug 1), Guanacaste Prov., Costa Rica 100m 23 July 3pm while driving past this site we found a road kill Tamaandua. Took measurements, the skull (#762 s?), I opened up the rotten carcass to sex it.

Journal 24 July. 3.9 km SE Playa del Coco, Guanacaste Prov., Costa Rica 50m 1:30pm Sitting here in the Juan air restaurant adjacent to our hotel ( # 280 colones), looking out at the bay. Beers are #17 but Jim Beam is #60 (as I learned last night). Yesterday we set 200 Sherman's up around the city dumps (not in g course). About 1/2-1/2 uphill - downhill. I set 40 in shrubby 2° growth and open habitat (shrub up to overstory). The ground is dry but cover is 70-80% overall. Here I caught 4 Liomys salvini. Also set 40 traps in roadside grassland -- nothing caught there. Total captures were 23 individuals ( Duke = 9 ; El = 8 ; Plat = 6 ). None pregnant near as I can tell. This morning met up again w/ Heinz Pfug (flog), our new friend from Hans ? from Fian S of the Nicaragua Frontier. Heinz is a bit obnoxious, but a good sport. Native German. Flew w/ the Luftwaffe, spent some time bombing London; now a rancher. He & his worker Leonard drank a coca & beer w/ us before we went back to work on the animals. Tonight we'll set out bat nets. But not before we hit the annual festival in Liberia where the people celebrate the 1821 Secession from Nicaragua at accession to Costa Rica. 25 July 10am Had a bit of a bonnet in Liberia last night. Unfortunately, we never set the bat nets - it started raining at the festival & we were having such a good time.

Journal Playas del Coco, Guanacaste Prov., Costa Rica 28 July The festival was quite an experience. Much food, music, exhibitions (bramcows, goats) & many horses. Beautiful horses! A small ferris wheel entertained the children and a salsa band, the adults. I ran into Leonard from Playas del Coco, who introduced me to Lucia. Later Lucia, Duke, Ed, & Lucias friends went to a discothegue in Liberia Pretty wild. Lucias friend Annie taught me spanish over rum & coke the better part of the night, in addition to dancing of course. Tilaran, Guanacaste Province, Costa Rica 56am 29 July We're in a hotel room in Tilaran. It's 9 pm. Today we set 150 Sherman at the 4.1 km E Tilaran locality. Ed & I set 70 traps in the riparian forest on the south side of the stream. of the 40 I set, 5 were directly streamside (for Rheomys w/ luck) & 35 were in 2o forest w/ (>100% crown cover) w/ moderately dense (40-60%) shrub-small tree cover. My line was closely paralleled the stream while Ed's franelleded (& was closer to) the edge - directly beyond which is the farmland-pasture land. The riparian strip is a mere 15-30m deep on this side & considerably more narrow (becoming absent) on the stream's north side. Duke set his traps like the same stream on the other side of the road. We also set traps just in a small forest in Tilaran.

Journal 28 July 1 km W, 4 km N Santa Ana, Prov. San Jose Costa Rica with an equally promising understory of many logs etc. Can't understand why we didn't catch anything. En route to this locality last evening we looked around for other suitable habitat between Escazu, Ciudad Colon, Santa Ana etc. (all along Hwy 7). The director of the cellular & molecular biology lab at UCR told us of a forest mature -1 extensive out this way. El + I found the Futuro Zoologin Park outside of Colon --> too park-like (open rolling hills w) much cropped grass, small copses of trees) for rodents. How did the caretaker want us to trap there. So we drove out the Hwy N of Santa Ana leading toward the freeway which runs east to San Jose. Anyways - we caught nothing there. 630 pm out of Cocori to meet the OTS folks for dinner. San Jose 29 July packed up our things at 11am, went to the university to pick up our supplies, etc. The hotel bill was $380 for all three of us split-night (@$462 to the dollar). 12pm leave university for Turrialba vicinity (east of Cartago). 29 July 5.6 km SE Turrialba, Prov.

Journal 5.6 1am SE Turrialba, Prov Cartago, Costa Rica 450m no promise for heteromyg. This [illegible] locality is just over ( ) the huge crossing of the Rio Relevezon. Secondary forest, very dense undergrowth. Ferns. Llanas. Prickly vines. Assorted cloud forest plants. The slopes bordering the forest are steep (from sheer faces to 100% slopes) - much of the area is only accessible by hiking up the trail/abandoned road to the E of the river where the bank bordering the forest is only several meters high. This is all to say that access is difficult. [illegible] After setting 80 Sherman's in this forest, I'm unsure of what to expect. Probably nothing, or at best very little. Many parts of the forest are too steep for rodents and much of it is narrow in width (<20m), being bordered by cane & banana fields. 7:00pm In the town of Turrialba - had a difficult time finding a hotel. Found one finally for $150. 7:30-9:30pm dinner & drinks at a local restaurant. 20 July 0630 staff rise to queue and head out for our traps 1000am Captures numbered 7: Reithro davis, Oryzomys #? and 5 heteromyg desmarestianus. Not bad. All animals saved alive. 10:30am leave for Part Limon 4.6 km W Puerto Limon, Prov. Limon, Costa Rica 30 July arrived in Limon round 130pm.

Journal 4.6 Km W Puerto Limon, Prov. Limon Costa Rica. 30 July For a short while we entertained ideas about heading toward Cahuita to the south. But the road is gravel and everything aside it is cultivated no forest. Instead we found this locality west of Limon secondary (perhaps tertiary) forest, well developed understory, Overstory project 40-60%. Rolling hills w/ slopes on 10% grade. Pleasant enough except for the bees and ants. leaf-cutting ants are in incredible abundance we set 180 traps here. I also set up 2 bat nets - one large, one small. 930pm arrived back on site to unfold the bat nets. 10pm In half an hour we netted nearly 10 Artibeus, and another unknown phyllostomid. 8 specimens were bagged (live) and the rest released. This was in the short (15') net. The large net (35') was left overnight. At the time of our departure at 1030pm there were no captures in this net. 31 July Returned this am at 7, found Desmodus, Artibeus & several unknown genera in the nets. Only one Desmodus. Probably 15 Artibeus. Four of the large bat of very long more leaves. Roughly half were released. Total count of bats kept can be obtained from the catalogue. The rodent catch from this locality was 9 Heteromys desmarestianus, 2 Oryzomy sp., 4 Nectomys (?) 1130am pack up & head west for San Jose.

Journal. S Villa Colon, Prov. San Jose, Costa Rica 740m 31 July. Arrived here round 3:30pm after driving from San Jose. Before leaving San Jose we secured a 'suite' in the Pension Americana off Ave Central. What a dirt! But for $150 it will serve its purpose tonight. We drove west out Paseo Colon, onto the freeway and south to the Villa (or Ciudad) Colon exit. From here we drove into Villa Colon for lunch. The locality we were told about lies southwest of Colon. After scouting out the area we decided on the dirt road shown above. Followed this out to a river. Just before the river to the left is [illegible] our first locality, 90 traps set here. Continuing over the river another km, we found another 2° forest. Neither are particularly good it seems, but this area is heavily settled. 6:30pm after setting out 90 traps at the second locality, we leave for town. 7:00-9pm prepare the remaining traps. 1 August Leave Pension Americana for the trapping sites. Site 1: 2 Proechimys semispinosus, 1 Sigmodon hispidus. Site 2: 2 Proechimys semispinosus, 8 Liomys salvini The proechimys were caught in 2 situations. The first (site 1) was fairly dense undergrowth – herbaceous. The second (site 2 and at the Puerto Limon locality) is fairly open 2° forest.

Left Berkeley round 2 pm, arrived 11 pm or so. Set 60 shermans in creosote send east of Coso Jct 1 1/2 miles and 30 shermans at this locality along the aqueduct. Then we slept, awoke late (it was a long drive) and checked the lines. Captures were as follows: in creosote flats P. merriami ♀ 2 ♂ 2 P. longimembris ♀ 2 ♂ 1 Neotoma ad ♂ 1 , juv. 1 P. maniculatus ♀ 1 along aqueduct: P. formosus ♂ 1 P. longimembris ♂ 1 P. maniculatus ♀ 1 (very pregnant) One ♀ merriami seemed to have given birth in last week: nipples distended, belly not bulging The other ♀ I kept — she appears pregnant. One ♀ longimembris died an accident in trap — she had embryos 3L,2R, swelling ~ 10 mm. The other ♀ is also pregnant. Kept her w/ ♀ merriami. The ♂ merriami show “receding testes”: scrotal but easy caudal epididymis

The plants change a bit (ponderose juniper > bigger juniper). The spring which creates a small (very small) ravine to south of the trail runs year-long apparently (B. Lawrence, pers. comm.). Overall, however, The habitat doesn't seem quite very good for Bassariscus -- the northward slope is far too great. The southward slope is manageable but the hilltop < 50 m. above supports oak savannah and residential habitats. Possible for ringtails, yet unlikely. at trails base (Folsom Lake) we did left along horstrail (north west) several hundred feet, then turned north across the stream (via wooden bridge) It is along this stream that ring tails are likely to be found. The hillside slope ~ 30-55% from oak woodland hilltops -- above the stream ~ 50 meters. The hillsides are vegetated w/ live oaks -- in some places, the habitat is more grassland than woodland. By and

It seems pretty warm relative to normal (~50°c) Too dark to set gopher traps, so stopped in at Little Lake for a beer. Met 60-year old Doris Bliss. She'd had thru 3 husbands, and was out seeing the sights in her VW bug; had quite a few laughs. Slept above Coso Jct. 22 Jan 5am Started setting gopher traps. The gopher sign (fresh wounds i.e.) isn't everywhere (as in spring/summer). Fresh wounds are found every 20-50 feet in the area near the roads. But in the interior, they seem to be more sparse. Set 35 meacles at 25 stations; and all 8 my livetraps (35). 10pm Eating dinner at Olancha. I catalogued 8 gophers thus far. 3've got 4 live ones awaiting numbers. No males yet - all females. All 8 them are in reproductive condition. The uteri are swollen in all cases - some of them greatly so, with vascularization/placentation sign. I clipped 4 or 5 out and preserved them in alcohol... One female (924) had 6 embryos - probably about 5mm long.

P. Brysll 1985 Journal Rose Valley Ranch, 2.5 mi N Coso Jct., Inyo Co. Calif. 22 Jan It's difficult to say what reproductive "state" the swollen uteri represent. Have the zygotes/blastulas implanted? [illegible] or are the [illegible] uteri swollen to prepare for implantation? I suspect they've implanted, probably within the last several days. Interestingly, though, the males are nowhere to be found. Delayed implantation? I doubt it. 11pm Checked the live traps again before turning in. Caught 4, [illegible] I'll catalogue them with today's catch. This brings to 13 the total number gophers cought here today. 23 Jan Can keep up to check the "catch" from the macaber and live-trap sets at RVR. After the coffee. "Red" (John) is staying here at the trailer on the south end of the field. I slept on the floor.

Gopher sign from the snow-pack days is in abundance, as at Rose Valley. Here and there are fresh mounds, indicating that there's been little recent activity. I set 15 sets of live-traps, most of them consisting of 2 traps/station. I stayed pretty close to the spur road going up Freeman Cyn (parallel to Hwy 178), so that I might easier find them at night. 6pm It's getting dark now and I've checked & rechecked the traps for activity. Several gophers responded to the challenge of an open burrow, but most did not, yet. No captures. 8pm Still no captures. 9pm Checked and reset trapes for last time tonight. I've reset nearly everyone, since the gophers are still out-witting me. Off to Inyokern to spend the night. 11pm had dinner at "Two Sisters Plus One" in Inyokern but no rooms to let. Convention time they say.

P. Brylski 1985 Journal Rose Valley Ranch and Freeman Gym (see previous pg.) 2-8 Feb traps. In all 7 the trap nights thus far, I've captured mostly ff. I caught 3 mf at Rose Valley from 2-8 Feb (117f). The mf of fs from Freeman Gym is somewhat higher, particularly because of the last several days (7-8 Feb.). From 4-6 Feb I caught 0 of fs at Freeman Gym (and 89f's). On 7 Feb I caught 1 m (24f) and 3 mf today, 8 Feb (24f's). It appears the of fs were mainly below ground, until recently. Now their abundance or activity above ground (ie, mounds) is about the same as the ff at Freeman Gym. Tomorrow (9 Feb) I'll start concentrating again at RVR. Births: only a single f gave birth definitely. This is a large f from RVR (PVB # 953). She gave birth to ~ 5 2 nights ago. The young (some of them anyway) are still alive, as evidenced by the squealing. I haven't yet heard squeals from other cages, so presumably no others have given birth yet.
