NOBRE, Pedro H et al. Bat assemblages from mountain forest areas in the serra negra region, southeastern Brazil. Mastozool. neotrop. [online]. 2013, vol.20, n.2, pp.279-287. ISSN 1666-0536.

The aim of this work was to describe the community composition of bats in mountain forest areas in the Serra Negra region, southeastern Brazil, and to compare species diversity and richness between the southern and northern slopes of mountain chain. During November 2007 to March 2010 a total of 608 captures of 19 bat species belonging to families Phyllostomidae and Vespertilionidae were obtained with mist-nets. Phyllostomidae constituted approximately 97% of the captures, and represented by 15 species, and Vespertilionidae nearly 3% of the captures, represented by 4 species. Sturnira lilium was the most frequently captured species (n = 207), followed by Carollia perspicillata (n = 154), Desmodus rotundus (n = 98) and Artibeus lituratus (n = 50). The number of species found (19) is close to the richness estimated by Chao 1 index (21.7). There was no difference in Simpson diversity indices between the slopes, and rarefaction analysis also showed that there was no difference in species richness. The relative abundance of species was different between northern and southern slopes of Serra Negra, as noted by differences in captures of the most common species. Although the availability of food resources was not directly assessed, some data previously recorded in Serra Negra suggest that the presence of more abundant species may be linked to the availability of food resources.
