Pearson - 1993 1 Journal- 1993 31 October.- Bariloche. Arrived by plane 3 pm. Steppe completely brown from the air, although lots of small ponds. The mallin at Estancia Condor sort of green but not very; lots of sheep in it. Quite a bit of Scotch broom blooming but not nearly maximum; Notro just starting to bloom in town. Apple trees blooming. Met Michael Christie on the street. He went to see the Puyehue bamboo last summer or autumn and saw flocks of pigeons feeding on the culms but not seedlings or seeds on the ground. The spring had been warm for a while, then turned cold. A lot of rain in September, plus a big storm last April that washed out bridges etc. The Lake level up over the breakwater at the new Port. He is leaving for Puerto Madryn for some Wildlife meetings. 1 November.- Bariloche. Visited Ecotono in the morning. Nadia Gutman was there, Werner Flueck, and Rapoport, plus three or four others. They have added about three rooms. Nadia reports that Eligmodontia is very scarce on their grids, Akodon xanthorhinus OK, Reithrodon fairly abundant. They had some flooding on or near their grid. Drove to the Llao Llao Peninsula after lunch and checked on our bamboo, then drove home via Colonia Suiza, checking up on places to trap for xantho and olivaceous. Found an intersting little-grazed area a couple of kms west of the bridge at Arroyo Casa de Piedras. The habitat at Casa de Piedras still looks OK (deserty), and still some good steppe/scrub nire habitat beyond and behind the Centro Atomico. See especially a soccer field south of Barrio Puerto Perito Moreno, which should be in the middle of the hybrid zone. The Hippodromo habitat now has a lot of houses on it, and the marsh where we used to catch olivaceous seems to have been mostly drained and heavily grazed. Day mostly sunny, breezy. November 2.- Bariloche. To Ecotono in the morning to talk with Adrian, Karin, Nadia, and Mariana. They have a live Ako olivaceous and are planning to try some crosses between xantho and olivaceous. They have chosen 8 "types" for toothwear ageing of xantho and loaned me about 30 cleaned skulls to check their ageing. They agree lots of Reithrodons and hares on their study area this year, including already a 10-
