Pearson-1992 13 mother? clump had definitely been dead longer than Peter's clump, and Peter's clump had not bloomed long e enough ago to have produced offspring with 9, 6, and 4 culms. The study clump D2 had no new shoots, 2 yearling shoots. The study clump D1 had 2 yearling shoots, no new shoots. One of the culms that had flowered 2 years ago has long branches still but no seeds or flowers left. The culm is slightly greenish but no leaves. But some marked culms that had bloomed two years ago still have a few green leaves, and one even had a few new new flowers. One of the blooming clumps along the road in the census had only 21 culms, graded in size up to about 12 mm diam. One culm had been broken off, and only one node, the one below the break, had any signs of life. It had flowers. Nearby were two very dead clumps. Met tour guide Sergio on the boat on the way home. November 24.- Temp 55, scattered clouds. Returned the amberat proofs to Fittkau. Christie came by. Paul Sherman's student is coming December 3 to look at Ctenomys sociabilis. Michael says he sees mink dead on the road between here and Confluencia about twice each year. November 25.- Temp. 55. Morning clear then cloudy. Read Monjeau manuscripts. In the afternoon went to Laguna Los Juncos/Esacion Perito Moreno/ Marful's where we did the Reithrodon study. Vegetation is lush, green. Many Reithrodon droppings scattered here and there, but out in the meadow I found no active holes or "colonies". But obviously there are numerous Reithros. A flock of 12 tero-teros screamed at me; Anita saw 5 condors circling the cliff, numerous hare droppings but no hares squashed on the road. Picked up about a liter of owl pellets in the big cave, size about right for Tyto. Saw no owl. Two pairs of buzzard eagles, a family of caranchos, California quail. Saw a fox en route. Cloudy/drizzly. November 26.- Bariloche. 55, cloudy drizzly. Worked with Akodon xanthorhinus skulls at Ecotono with Adrian, Karin, and Mariana. They have at least one skull of an 8-gram individual that died in the trap 8 months later. It seems to fall in the ault/old category. Their numbers up to 50 or 60 xanthorhinus and Eligmodontia on their study grid seem to be OK, but their density calculations do not include a border strip. They suspect a temperature effect on Sherman traps that make them less sensitive at hot (or cold?) temperatures. As many as a dozen unsprung but with with bait gone and droppings inside, yet apparently sensitive when tested. November 27.- Bariloche. Temp. 57, cloudy. To Ecotono in morning. They are ageing xanthorhinus. Gladys Galende
