Bat diversity in three roosts in the Coast region of Oaxaca, México
In this paper, we analyze the richness, abundance, diversity and trophic guilds in a mine (La Mina) and two caves (El Apanguito and Cerro Huatulco) in the municipalities of Pluma Hidalgo and Santa María Huatulco, in the state of Oaxaca, México, a state with high species richness of bats nationwide. Fieldwork was conducted from July 2016 to June 2017. Using a harp trap, we captured 5,836 bats belonging to 14 species, 10 genera and five families. The greatest species richness was found in Cerro Huatulco (12 species), followed by La Mina (nine species) and El Apanguito (four species). Overall, the most abundant species were Pteronotus fulvus (40.59% of captures) and Pteronotus mesoamericanus (32.01%). Half of the species captured corresponded to the insectivore trophic guild. Results show that the three roosts, but particularly Cerro Huatulco and El Apanguito, maintain high species richness and abundances of individuals due to processes that favor colonies of thousands of individuals. We therefore argue that they represent priority roosts for the conservation of bats in the State of Oaxaca.
