CORBALAN, Valeria E.  y  OJEDA, Ricardo A.. Home range of a rodent population in the Monte desert (Mendoza, Argentina). Mastozool. neotrop. [online]. 2005, vol.12, n.2, pp.145-152. ISSN 0327-9383.

In the central portion of the Monte desert four small rodent species coexist: Graomys griseoflavus, Akodon molinae, Eligmodontia typus, and Calomys musculinus . Using the Convex Polygon Method, we assessed the home range of these species at different habitats and made comparisons among species, and between sexes and different seasons of the year. We found that home range did not differ among species, but there is a tendency to increase range size as the species corporal size increases. Overlapping of home range was different at different seasons of the year, probably due to different population densities, but home range size was constant along the year. Habitat type and sex affect home range only for G. griseoflavus and A. molinae, respectively.
