Abstract

Extensive livestock farming has caused negative effects on biodiversity, affecting the functioning of dry ecosystems in the Colombian Caribbean. The objective was to evaluate the eeffect of livestock management on the diversity of bats associated with bs-T fragments. During a year-long fieldwork, I know They identified 39 species of bats distributed in 23 genera and six families. The Phyllostomidae family presented the highest species richness, with Stenodermatinae being the most abundant group. The assembly of species in the SSP presented greater equity, with a relative abundance by species and foraging guilds, significantly higher in the SSP. The capture success presented a significant temporal variation (rains and drought), with greater abundance during the rainy season. Artibeus planirostris, Artibeus lituratus, Carollia perspicillata, Carollia castanea, Phyllostomus discolor, Dermanura phaeotis, Uroderma convexum, Glossophaga soricina, C. brevicauda were the most abundant species. Fruit bats showed greater temporal stability in SSP environments; while, in SC fragments the rate of species turnover was higher. The research indicates a positive effect of silvopastoral management of extensive livestock farming on bat diversity, diminishing the negative effect of biodiversity loss.
