mammalian fauna of the eastern Caatinga, a Brazilian semiarid biome,
was surveyed in the dry and wet seasons aiming to contribute to the
knowledge of this poorly known region. Complementary live-trapsurvey methods were employed for sampling small non-volant mammals and transects along roads for medium and large mammals.
mammalian species were recorded, with five new records for Sergipe
state, two being endemic to Caatinga. More individuals were captured in
the dry season, although species number was the same for both seasons.
Medium- and large-sized mammalian species were not encountered in the
region, which was also true for some small-sized species hunted for
findings corroborate the importance of using complementary methods for
sampling small non-volant mammals in the Caatinga and indicate that the
mammalian fauna of this region, suffering a severeanthropogenic pressure, requires strong measures for its preservation.
