Resumen:
The only living representative of Microbiotheriidae, one of the oldest lineages of marsupials, is Dromiciops gliroides (Philippi, 1893, monito del monte). This marsupial is endemic to the northern portion of the temperate forest of Patagonia, between 361 and 431 South in Chile and Argentina, where it dwells mainly old-growth Nothofagus forest. Morphological, chromosomal and molecular studies suggest that this marsupial shares more phylogenetic affinity with the Australian marsupials (Diprotodontia) than with other South American marsupials (Didelphidae). The objectives of this study were (1) to estimate population abundance, and (2) to describe the population structure of monitos del monte in an old-growth Nothofagus forest in the temperate forest of Patagonia. This study constitutes the first detailed ecological research focused on the identification of the population characteristics of the monito del monte.
