Few data are available on the predation of amphibians, reptiles, and mammals by the fringe-lipped bat Trachops cirrhosus (Chiroptera: Phyllostomidae: Phyllostominae), in particular in Brazil, where ecological studies of this species are still incipient. This study presents an overview of the data available in the literature on the composition of the diet of T. cirrhosus, including data from a semiarid region. The first records of the predation of the anurans Corythomanthis greeningi (Hylidae), Pleurodema diplolister (Leiuperidae), Proceratophrys cristiceps (Cycloramphidae), Dermatonotus muelleri (Microhylidae), Pipa carvalhoi (Pipidae), Leptodactylus sp. (Leptodactylidae), the lizards Vanzosaura rubricauda (Gymnophytalmidae), Hemidactylus mabouia (Gekknonidae), and a rodent of the family Cricetidae are reported. Insects (33%) constitute the principal component of the diet of T. cirrhosus, while anuran amphibians contributed 23% of the items recorded, followed by birds (14%), mammals (10%), lizards (8%), and invertebrates (8%). This diversity of prey is typical of a generalist predator, which is relatively unaffected by seasonal fluctuations in the availability of prey. This is especially important in the semi-arid Caatinga biome, which is subject to prolonged periods of drought that result in a shortage of feeding resources.
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.
