Item Predation of a mustached bat, Pteronotus sp. (Mormoopidae), by an Amazon tree boa, Corallus hortulanus (Boidae), in the Brazilian Amazon(2023) Barbier, Eder; Pimentel, Narjara Tércia; Bernard, EnricoSeveral bat species use caves as roosts and some of these caves can harbor high concentrations of individuals. Such caves may represent opportunities for certain predators, benefiting from the concentration of potential prey. Here, we report the predation of a Pteronotus bat by a Corallus hortulanus in the Brazilian Amazon. On three occasions over a year, individuals of C. hortulanus were observed around a cave that harbors populations containing tens of thousands of bats. On one occasion, an individual of this snake species was observed preying on a Pteronotus sp. as it left the cave. Our record extends the known diet for C. hortulanus, documenting the predation of a mormoopid bat by this snake species for the first time. This record reinforces the need for longitudinal studies at sites with exceptional bat populations to gain a deeper understanding of the ecological predator-prey relationships involving this diverse group of mammals.Item Streblid flies parasitizing cave bats in Carajás, Amazonia, with a new record for Brazil(2023) Barbier, Eder; Bernard, EnricoStreblid flies (Diptera: Streblidae) are hematophagous and highly specialized parasitic insects, found only on bats (Chiroptera). Caves are important roosts for bats but, despite harboring high bat richness, relatively few studies exist on the ecology and biology of streblid flies in cave environments, especially in Amazonia, the largest domain in northern Brazil, with >140 bat species and thousands of caves. To fill some of the gaps in the geographical distribution and interspecific relationships for streblid flies in the region, we sampled bats in six caves in Carajás National Forest, a protected area in Pará state (Brazil). Thirteen of the 14 streblid species found are new records for Carajás, with three new records for Pará state and two for the northern region of Brazil. Nycterophilia fairchildi was recorded for the first time in Brazil. Most streblids had host-specific behavior, however, N. fairchildi, Trichobius caecus, and T. johnsonae were less host-specific, parasitizing different Pteronotus bat species. The gregarious behavior of Pteronotus species and the spatial distribution of their colonies within the caves may be important factors in the flies’ exchange among congener hosts and deserve special attention in future studies. Furthermore, studies on ecological interaction networks between bats and their ectoparasitic flies in caves will be useful for a broader understanding of how this relationship is structured over time and space, as well as its impact on both bats and flies.Item The bats of Rio Grande do Norte state, northeastern Brazil(Biota Neotropica, 2018-04-16) Vargas-Mena, Juan Carlos; Pereira, Kleytone Alves; Barros, Marília Abero Sá; Barbier, Eder; Schmidt, Eugenia Cordero; Lima, Sergio Maia Queiroz; Herrera, Bernal Rodríguez; Venticinque, Eduardo Martins
