D'ANDREA, Paulo Sergio et al. Ecology of small mammals in a Brazilian rural area. Rev. Bras. Zool. [online]. 1999, vol.16, n.3, pp.611-620. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81751999000300002.

A small mammal study was carried out in Pamparrão valley, Sumidouro, State of Rio de Janeiro, Brazil, from June 1991 to July 1996. The area was characterised by small rural properties with vegetable plantations, pasture lands and small forest fragments. Small mammals were captured in seven line transects along the valley. Eleven small mammal species were captured: the didelphid marsupials Didelphis aurita, Philander frenata and Monodelphis americana, and the rodents Nectomys squamipes, Akodon cursor, Oligoryzomys nigripes, Bolomys lasiurus, Oecomys concolor (Sigmodontinae), Rattus ratlus (Murinae), Proechimys iheringi and Euryzygo-matomys guiara (Echimyidae). The heterogeneous habitat configuration probably allowed the occurrence of marsupials and more rodent species when compared to studies in monoculture areas.

Keywords : marsupials; rodents; cultivated areas; Brazil.
