Resumo: | We used mark and recapture techniques to evaluate movements of bats within and between three brazilian forest remnants. We captured bats with mist-nets in four 1 ha plots representing different degrees of isolation of riparian (two plots) and submontane (two plots) forests between July 2002 and June 2003. Using numbered aluminium tags, we marked 635 bats of seven species and 54 individuals of six species were recaptured. Overall, we recaptured Carollia perspicillata (Linnaeus, 1758) (short-tailed fruit bat) most frequently, especially in plots where they were banded in the riparian forest plots. These results suggest that this bat has restricted feeding areas, which are probably determined by the abundance of Piper Linnaeus (Piperaceae), its preferred food item. In contrast, species of the genus Artibeus Leach, 1821 exhibited few recaptures, suggesting high mobility and larger feeding areas. In fact Artibeus seems to use more of the forest remnants in their search for food, especially Ficus Linnaeus (Moraceae), the preferred food of this bat. Our results suggest that even small forest isolates are valuable for the maintenance of some bat species because they offer many of the resources they need or because they are spatially distributed in a pattern that allows use of the entire landscape.
