Abstract

CORBALAN, Valeria  and  DEBANDI, Guillermo. Evaluating microhabitat selection by Calomys musculinus (Rodentia: Cricetidae) in western Aargentina using luminous powders. Mastozool. neotrop. [online]. 2009, vol.16, n.1, pp.205-210. ISSN 0327-9383.

The aim of this study was to use fluorescent powder tracking techniques to study the use of space and the patterns of microhabitat selection in Calomys musculinus at the Ñacuñán Biosphere Reserve. The examination of over 3000 microhabitat records from the trails of eight individuals indicates that, in general, the species does not discriminate among major habitat types; however, we found significant differences in the specific categories of substrate used by the species within habitat. In addition, we also note that C. musculinus uses vertical habitats up to 50 cm.

Keywords : Monte desert; Ñacuñán; Biosphere Reserve; Sigmodontinae.
