| Home range size and habitat use of seropositive Oryzomys palustris, primary host for the Bayou strain of hantavirus, were compared to that of seronegative individuals from March 2002 - August 2003 in a longitudinal field population study. There were significant macrohabitat associations with serological status, but selection for most microhabitat variables did not differ between seropositive and seronegative animals. Seropositive adult males moved farther (had larger home ranges) than did seronegatives and were larger in terms of mass and testes size. These patterns may reflect the influence of infection on rodent ecology in terms of dominance and access to preferred habitats. |

| Recent field work in Paraguay has increased our knowledge of its mammal fauna, especially in terms of its distribution. Herein, we report three specimens of Monodelphis kunsi (Didelphidae), which are the first for the country and represent a significant range extension for this species. Two of the specimens come from a natural mixture of Cerrado and Atlantic Forest, on eastern Paraguay, whereas the third one is from the central Chaco. We review other records of Monodelphis species for the country and discuss geographic variation among M. kunsi specimens in Paraguay, as well as in regard to previous records in South America. Although this wide geographic range includes distinct habitats, we found no evidence of significant variation among specimens. |
