Aconaemys Fuscus
The Chilean rock rat (''Aconaemys fuscus'') is a species of rodent in the family Octodontidae. It is found in the high Andes of Argentina and Chile. Description The Chilean rock rat is a short-tailed rodent. Rock rats in the genus '' Aconaemys'' are similar to those in the genus '' Ctenomys'' but not so specialised for life underground. The ears are rather larger, the claws on the front feet which are used for digging are smaller, and the edging of hairs on the hind feet, used for shifting loose soil, is reduced in size. The upper parts of the Chilean rock rat are dark brown, with the underparts ranging from reddish brown to white. Sample specimens described in 1966 and 1984, from two different locations, had a head-and-body length ranging from to , with the tail adding another – to the animal's total length. Its karyotype has 2n = 56 and FN = 108. Distribution and habitat This species is endemic to parts of Argentina and Chile in the high Andes in South America. Its ran ...

Nothofagus
''Nothofagus'', also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea, and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. Description The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing one to seven nuts. Reproduction Many individual trees are extremely old, and at one time, some populations were thought to be unable to reproduce in present-day conditions where they were growing, except by suckering ( clon ...
