November 3- Bariloche. Temp 40, partly cloudy. Barometer
rising at last. Interviewed by Abel Basti for an
article on bamboo for La Manana del Sur. At 4 pm drove
to La Veranada to check our bamboo clumps. Only a few
surviving yearling shoots, but otherwise the same. The
clamp in the road right-of-way that we cut down years
ago is still alive, but hardly thriving. Then we
walked up into the lenga forest on the old trail. The
nire trees there are bigger than east of the road. The
bamboo becomes bigger and taller before you come to the
lenga trees. There was almost no snow left east of the
road, but much more right where the bamboo becomes
bigger. More shade? The lenga leaves are coming out,
but most of the nire are still pretty bare. Some of
the bent-over bamboo culms had a layer of snow on them
with a layer of lenga leaves on top of that, which
seems to say that there was early snow last fall before
the lenga leaves had fallen. Evening clear.
November 4- Bariloche. Temperature 38, clear, not windy.
Today's paper says that the very low temperatures,
strong winds, and the inclement weather during the
second half of October, the season of birth, may have
reduced the sheep/wool crop, partly through increased
fox predation. Quotes Ramon Marful, whose Estancia,
where we did the Reithrodon study, runs 3500 sheep on
8000 ha. It also quotes Adolfo Sarmiento at INTA who
said that he had heard of losses of sheep near
Pilcaniyeu, Cerro Alto, Las Bayas, Coquelen, and south
of Comallo.
Adrian Monjeau came by with his team of three
students: Nadia Guthman, Karin Heinemann, and Mariana
Losada. They have a graph of the longevity of about 50?
banded Akodon xanthorhinus. The oldest was about 10
months.
Visited Michael Christie's office. Only Miguel
Gross was there. Gallopin is moving to Cali, Colombia.
November 5- Bariloche. Morning 55, clear, not windy. Drove to
the rocky cliff overlooking Estancia Tehuel Malal and
hunted for owl pellets. I think an increase of rosa
mosqueta and of Colletia since last visit several years
ago. Found two or three liters of pellets and saw one
barn owl in a crevice in the cliff. No viscachas. A
dead elk and numerous elk droppings. Young maiten trees
are completely stripped of leaves and twigs. Sheep,
black Angus, horses, and hares grazing on the flats
down below.
On the way back to Bariloche in the afternoon, 50
or more hectares of grassy/bushy steppe was burning
furiously between the airport and the Lake (Estancia
Condor). Yesterday another freeze (-3C) hit Neuquen and
