BRITO DE OLIVEIRA, Marcione et al. COMPOSITION AND FREQUENCY OF CAPTURE OF BAT ASSEMBLAGES IN A LANDSCAPE MOSAIC IN NORTHERN PANTANAL, MATO GROSSO, BRAZIL. Mastozool. neotrop. [online]. 2020, vol.27, n.1, pp.39-52.  Epub 25-Maio-2020. ISSN 0327-9383.

Influence of landscape patches on species richness and frequency of bats was evaluated in a cattle ranch in northern Pantanal wetland. Besides the lack of information on bats in areas modified by ranching, land use and the seasonal flooding in the Pantanal wetland certainly affects bat fauna composition. Twenty-seven (27) species were captured, distributed in five families. Phyllostomidae predominated with 16 species, followed by Vespertilionidae with five species. Species richness and frequency of captures varied according to the landscape mosaic, presenting positive association to less altered areas. Species more sensitive to environmental disturbances were captured in the most conserved areas, associated to palm forests (acuri palm forest; Scheelea phalerata, acuri palm tree) and flooded forest (cambará forest; Vochysia divergens). Our data suggest that even vegetation units in extensively deforested areas are valuable for the maintenance of some species of bats, either because they offer many of the resources they need or because they are spatially arranged in order to facilitate the joint use of the landscape patches.
