Abstract

DA SILVA, Shirley S. P et al. Bats (mammalia: chiroptera) from the caatinga scrublands of the crateus region, northeastern Brazil, with new records for the state of Ceará. Mastozool. neotrop. [online]. 2015, vol.22, n.2, pp.335-348. ISSN 0327-9383.

Whereas surveys of the bat fauna are available for some localities in the Brazilian Northeast, stud­ies in the caatinga scrublands are still limited. The aim of this study was to survey the bat fauna in an area of caatinga scrublands in the Private Natural Heritage Reserve (RPPN Serra das Almas), which is located on the Ibiapaba Plateau, State of Ceará. The bat assemblage of the reserve was surveyed in July 2012 (rainy season), and January 2013 (dry season), with a total of 19 sampling nights. We captured 347 individuals of 23 species representing six families. The bat fauna was characterized by the predominance of a few abundant species, in particular phyllostomid frugivores, and many rare species, which is frequent in studies based on mist nets at ground level. The first records of Tonatia saurophila and Chiroderma vizottoi (recently described and known only from its type locality) are reported for the State of Ceará, where 66 bat species are now known to occur.
