Diversidad y composición de murciélagos frugívoros en bosques secundarios de Tabasco, México

Abstract

We captured bats using mist nets in 4 secondary forests that represent a perturbation gradient in Southeast Mexico, in order to compare frugivore bat species richness, diversity and composition. We captured 691 frugivorous bats from 15 species; Artibeus jamaicensis (A. jamaicensis) and Sturnira lilium (S. lilium) were the most abundant. There were no significant differences in frugivorous bat richness and diversity in secondary forests, although species composition was notably different, S. lilium, A. jamaicensis, Glossophaga soricina, Artibeus lituratus and Carollia sowelli contributed the most to differences. Secondary forests are important for frugivorous bats conservation and in general for wildlife, since they are the last refuges in the Tabasco coastal plain, a region dominated by grasslands and urban areas.
