Bat Fauna (Chiroptera) in an urban environment in the Atlantic Forest, northeastern Brazil

Abstract

In Brazil, only few works have been conducted regarding urban bats and information about richness, composition and ecological interactions in urban areas is little known. Additional studies are important to understand the dynamic of urban bats and offer strategies for their protection. In this paper, we present the results of a bat inventory at the Dois Irmãos campus of UFRPE, Recife, Pernambuco, northeastern Brazil, with analyzes of the composition, richness, diversity, and seasonal variation. From May 2006 to April 2007, we captured 950 bats from 16 species (five families). Frugivores bats accounted for 84.42% of the captures, followed by insectivores, piscivorous, nectarivores, omnivores, and hematophages. The species Artibeus planirostris was the most abundant. There was no significant difference (t = 0.35443, p = 0.7257) on abundance between the seasons of the year. We observed a richer and more diverse bat fauna as one would expect in an urban area, which suggests that the campus is being used for foraging, commuting, or as shelters for these animals.
