DE TOMMASO, Daniela C et al. Distribución geográfica de Calomys musculinus (Rodentia, Sigmodontinae) en Patagonia. Mastozool. neotrop. [online]. 2014, vol.21, n.1, pp.121-127. ISSN 0327-9383.

The aim of this paper is to document-based on both published and unpublished data-the geographical distribution of Calomys musculinus in Patagonia. We compiled 165 recording localities of which 104 are new. The species is widely distributed in Patagonia. Its geographic range coincides in northeastern Patagonia with the Monte Phytogeographical Province; to the south and west it is associated with coastal environments and major river valleys, respectively. In the last hundred years the populations of C. musculinus have experienced local dramatic increases, which are plausibly related to the establishment of agricultural oasis.
