The composition, diversity, diet and the reproduction of bats in a community located between the morfoclimatic dominiun of the Atlantic Forest and the Caatinga area from Sergipe was studied. One hundred eighty-three bats of 16 species were captured, with the predominance of bats of the family Phyllostomidae, specially the subfamily Stenodermatinae. In general, the captured species are inside their known areas distribution, a with exception of Chiroderma doriae, which is considered endemic of the Southeast region and it was collected in the present study. The collected species showed significant differences to the proportion of species that occur exclusively in the open areas. The monthly frequency of captures was also significant in relation to the monthly frequency of captures, proportion of the collected individuals and number of species collected in the open end closed habitats. The frugivous species were predominant. The period of the activity of the bats was significant between the collected periods, the first four hours after the sunset was the highest moment of activity. It was collected 3 to 5 times more bats between 18:00 24:00 hours.The sexual proportion was 2 females for 1 male. It was analyzed histologically the gonads of 42 males, 37 of those (88%) had spermatozoa in the seminiferous tubules and in the epididymis. There was not significant differences in relation to the monthly variation of the reproductive males, suggesting reproductive synchronism among the males of the studied community. From the total of females captured (n = 117), 79 (67,5%) were reproductive. With the exception of A. lituratus, C. perspicillata and P. lineatus, apparently the reproductive monthly female distribution of the other species is homogeneous.
