SUMMARY:

Urbanization of natural habitats alters communities of living beings and their relationships. Although some species are considered well established in anthropized environments, bats are susceptible to low-quality resources and new threats characteristic of urbanization, such as stress, bioaccumulation, and parasitism. The objective of this study was to evaluate the body condition, parasite ecology, stress, and ecotoxicology of bats in response to urbanization in the Caatinga Morphoclimatic Domain. In five sampling units (SUs) with distinct characteristics, 196 bats of 12 species were captured during thirty nights in the field. In addition to the morphometric parameters, hair samples were collected to evaluate the mineral profile, as well as hematophagous flies. There was dominance of frugivorous phyllostomid bats, collectors of disorganized spaces, with emphasis on the species Artibeus planirostris, and also the aerial insectivore of disorganized spaces, Myotis lavali. The SUs did not show significant differences in terms of average abundance and species diversity, and the accumulation and rarefaction curves did not stabilize during the sampling period. The dry and rainy seasons did not affect species richness, but they seem to influence species composition. It was not possible to perform analyses regarding the reproductive period due to the size of the samples of individuals in these conditions. Regarding parasitic indices, 37% of the bats were infested, and there was no influence of host sex on parasitism. The most infested species were A. planirostris and M. lavali, and the fly Basilia travassosi was the most abundant. There were no significant differences between the areas regarding abundance and the dry and rainy seasons. Only one host species, A. planirostris, was common to all SUs. Thus, the information obtained demonstrated that there is still room to explore in these environments regarding the effects of urbanization, and that more specific answers and inferences will be provided based on analyses of the mineral profile and body condition.
