Influence of the size and degree of conservation of remnants of the Atlantic rain forest on chiropteran assemblages

Abstract

Reduction in the size and loss of the quality of habitats are considered the greatest threats to bat species. Aiming to complement information, the objective of this study was to evaluate, from compiled data, the influence of the size of forest fragments and their degree of conservation on the richness and composition of chiropteran fauna in the Atlantic rain forest. A total of 33 publications on Chiroptera in the Atlanticrain forest was reviewed and a list of 86 species was extracted from them. The size of forest fragments exhibited positive and significant relationship with the total number of Relatively Common Species, Rare Species, Not Generalist species and with richness. Positive and significant relationship was observed between degree of conservation of the forest fragments and the total number of Rare Species, of Not Generalist species and with richness. The results here presented indicate that largeand well-conserved fragments of Atlantic rain forest should be the priority when the intention is to maintain a high richness of Chiroptera and of Rare Species and Not Generalist Species.

First record of Sturnira tildae De La Torre, 1859 (Chiroptera, Phyllostomidae) for the State of Pernambuco, Brazil

“…In the present study, we observed higher abundance of S. lillium compared to S. tildae (Table 1), a pattern that is maintained throughout the Atlantic Forest (Faria 2006, Faria & Baumgarten 2007, Brito 2011, Carvalho et al 2013, Luz et al 2013, Pires & Cademartori 2018. In the Atlantic Forest of Northeast Brazil (present study, Faria 2006, Faria & Baumgarten 2007 the abundance of S. lillium is lower than in the southern portion of this biome (Passos et al 2003, Esbérard et al 2006, Brito 2011, Carvalho et al 2013, Luz et al 2013, Souza et al 2015).…”

Distribution extension and first record of Trinycteris nicefori Sanborn, 1949 (Chiroptera, Phyllostomidae) from the state of Pernambuco, Brazil

“…Historically, bats were sampled in this area only in the vicinity of the zoo. As T. nicefori is considered to be a rare specialist species in the Atlantic Forest domain (Pires and Cadermatori 2018), the record from the PEDI indicates that a comprehensive sampling effort can guarantee a more definitive inventory of the bat diversity of an area, even in highly impacted urban forest fragments. within the scope of this research program.…”
