Sumario:Geographic variation is a conspicuous phenomenon in nature and its study is fundamental to understand the causes of the population differentiation of the species. Moreover, such information is critical for species with conservation problems. The "monito del monte" Dromiciops gliroides (Thomas, 1894) is a small endemic marsupial of the temperate forests of southern South America, whose populations could be threatened due to the deep fragmentation of their native habitat. In this Thesis, the geographic variation of the "monito del monte" populations was analyzed using morphological and genetic approaches. We studied populations from both the continental range and the Chiloé Island, in south-central Chile. The results obtained are discussed in terms of the probable causes of the geographical differentiation of the populations of this marsupial, as well as the potential use of these data for the resolution of recent proposals on their taxonomic status and for the conservation of this ancient lineage.
