| Each animal species selects specific microhabitats for protection, foraging, or micro-climate. To understand the distribution patterns of small mammals on the ground and in the understorey, we investigated the use of microhabitats by small mammals in a deciduous forest of southern Brazil. Ten trap stations with seven capture points were used to sample the following microhabitats: liana, fallen log, ground litter, terrestrial ferns, simple-trunk tree, forked tree, and Piper sp. shrubs. Seven field phases were conducted, each for eight consecutive days, from September 2006 through January 2008. Four species of rodents (Akodon montensis, Sooretamys angouya, Oligoryzomys nigripes and Mus musculus) and two species of marsupials (Didelphis albiventris and... |

| 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. |
