Exodus hours and seasonality of the bats in four caves from Dominican Republic
##plugins.themes.bootstrap3.article.main##
Abstract
Emergence patterns and reproductive status of populations of bats were studied in four caves of the Dominican Republic. Twelve species were captured: Mormoops blainvillei, Pteronotus parnellii, Pteronotus quadridens, Chilonatalus micropus, Natalus major, Artibeus jamaicensis, Brachyphylla pumila, Erophylla bombifrons, Macrotus waterhousii, Monophyllus redmani, Eptesicus fuscus and Phyllonycteris poeyi. Bats were captured more or less continuously between 18:15 and 23:00. From a total of 1,445 bats which were sexed, 969 were males (67.1%). The results show that the species in the caves are at different reproductive stages, with pregnant or lactating specimens belonging to two dominant families: Mormopidae and Phyllostomidae. In addition, we compared reports from Cuba and Puerto Rico, which show that some species may have longer breeding seasons than reported in this study.
