Mammalia, Didelphimorphia and Rodentia, Southwest of the province of Mendoza, Argentina.

Abstract

We documented terrestrial micromammal assemblages at five localities of southwestern Mendoza province,Argentina. We added new localities for several of the most uncommon small mammal species of this region (e.g.Loxodontomys micropus and Tympanoctomys barrerae). Two main groups of terrestrial non-volant micromammals arerepresented in southwestern province of Mendoza: one group is related to the South American arid diagonal, andincludes species typically adapted to the xeric environments of the Monte Desert; a second group includes Patagonianand High Andean species. Some Patagonian species reached in the study area their northernmost distributional records(e.g. Abrothrix longipilis, A. olivaceus, Chelemys macronyx, Loxodontomys micropus).
