Ecological analysis of three bat assemblages from conservation units in the Lowland Atlantic Forest of Rio de Janeiro, Brazil.
Menezes Schittini, Gilberto
In the present study we made a preliminary ecological analysis of the bat assemblages from threeconservation units in Rio de Janeiro state, southeastern Brazil: Reserva Biológica Poço das Antas, Fazenda RioVermelho and Reserva Biológica União. Two samples of bats were taken from each area, one during the rainyseason, and the other during the dry season. We described assemblages by species lists, richness, evenness,abundance distribution, and rarefaction curves. In all areas, Carollia perspicillata was the most frequent batspecies, presenting a relative abundance far superior from others. Rio Vermelho was the richest area, followed byUnião and Poço das Antas. Differences in spatial heterogeneity of the areas might explain differences found indiversity patterns.
