Comunidade de morcegos (Mammalia, Chiroptera) e suas moscas ectoparasitas (Diptera, Streblidae) na Reserva Particular do Patrimônio Natural Bom Retiro, Casemiro de Abreu, RJ, Brasil

Abstract

From January 2011 to June 2018, a survey of the chiropteran fauna of the Private Natural Heritage Reserve Bom Retiro, Silva Jardim, Rio de Janeiro, was carried out. Bats were captured in five sampling sites, using grund-level mist nets. In 19 campaigns, 540 individuals distributed in four families (Phyllostomidae, Vespertilionidae, Noctilionidae and Molossidae) and 19 species were captured. Carollia perspicillata was the most common species, representing 45.75% of the catches, possibly justified by the large presence of plants of the Piperacea family. Compared to seven other surveys conducted in the state of Rio de Janeiro, CPNHR Bom Retiro showed a low diversity. The collector curve, however, has not stabilized yet, and more species are expected to be added in new campaigns. In the comparison of two areas, one Forested and one Open, the first presented greater diversity, a fact that may be related by the greater availability of refuges and food in this area. Four bat species presented streblid infestation. Carolllia perspicillata was parasitized by eight fly species, while in Platyrrhinus lineatus two were recorded, and in Noctilio leporinus and Sturnira lilium just one. These results support those obtained in previous surveys carried out in São Paulo, Minas Gerais, and Paraná, closer states that differ from distant states such as Maranhão and the Federal District, which seems to be preponderant factor. The presence of Dermanura cinerea shows the importance of the reserve. This species is classified as vulnerable for Rio de Janeiro and is included in the List of Brazilian Endangered Animals. Despite showing great dominance of some species, the bat community of the RPPN Bom Retiro represents an important part of the fauna of this reserve, which still needs further studies
