M F Smith 1993 JOURNAL Bariloche, Prov. Rio Negro, Argentina Nov.24 We didn't catch any animals in the two traps near the burned area. In the meadow at the base of Cerro Renge in Payne's 22 Sherman traps there were 6 Abrothrix longipilis 1 Abrothrix olivaceus 1 Oligoryzomys longicaudatus, We processed the live animals when we got back to the apartment, after lunch & took tissues and made complete skeletons of some of the animals from the snap traps. At 4:30pm Payne and I went out to set traps in a clearing above the road up to Cerro Otto. We alternated Shermans and snap traps, about 24 of each. This habitat is mixed with some steppe plants and some plants of the moister forest. We will call this east knoll of Cerro Otto. Nov.25 Drove out at 7:30am to check the 48 traps on the east knoll of Cerro Otto. We got 2 animals: 1 Eligmodontia morgeni 1 Abrothrix xanthorhinus Both were in snap traps on the north facing slope. The Xanthorhinus looks like a typical representative of that type. Across the road only about 400 meters away we can see the meadow where we got a typical A. olivaceus.
