DURAN, Adrián Alonso  and  CANCHILA PEREZ, Silfredo. Bat assemblages (Mammalia: Chiroptera) in two areas of the Department of Sucre, Colombia. Acta Zool. Mex [online]. 2015, vol.31, n.3, pp.358-366. ISSN 2448-8445.

The objective of this study was to determine the structure and composition of two bat assemblages around the weather station Primates and "La Flojera" farm, in the department of Sucre, Colombia, from June 2011 to March 2012. The capture of bats was performed using mist nets, active from 18:00 to 24:00 h. We captured 427 bats belonging to 26 species, 17 genera, 6 subfamilies and 4 families. The family Phyllostomidae was the most diverse with 20 species. Of all caught individuals 97.9% belonged to the Phyllostomidae family. Artibeus planirostris was the most abundant with 139 individuals followed by, in decreasing order, Phyllostomus discolor with 56, Desmodus rotundus and Sturnira lilium with 37 individuals. According to the estimates of richness the sampling efficiency ranged between 80 and 90%. The most common trophic guild was the frugivorous guild (42.3%). The Shannon-Wiener diversity index was 2.40 in Primates and 2.0 in "La Flojera" farm. The species dominance was the highest (85%) in Primates Station. The similarity between the bat communities based on the index of Jaccard was 0.53. The differences found between the two bats communities can be related to differences in vegetation type at each locality.
