Species richness, new reports and inventory update of bat assemblage of the Gorgona National Natural Park, Colombia ; Riqueza de especies, nuevos registros y actualización del listado taxonómico de la comunidad de murciélagos del Parque Nacional Natural Gorgona, Colombia

The information resulting from inventories is crucial for tracking the effects of habitat alteration and climate change on biodiversity, and for determining conservation priorities. Bats provide several ecosystem services and reflect the status of the populations they interact with. However, the inventory of bats in Gorgona National Natural Park can be incomplete since relatively few intensive surveys have been done. Using mist nets in areas with different forest cover, 670 bats representing 10 species and three families (Emballonuridae, Phyllostomidae and Vespertilionidae) were captured. Frugivorous species were more abundant in the survey, but a higher number of insectivorous species were registered. A model that incorporates detectability suggests that 33 bat species occur (95% credible interval=[26,39]) and that frugivorous species have a higher detectability than other trophic guilds. To the 13 bat species reported for Gorgona, we added two: Peropteryx macrotisand Mimon crenulatum. In conclusion, our results add two new records of bats to Gorgona, and suggest that the inventory of bats in Gorgona is incomplete, and aerial insectivorous bats have been underrepresented because of the exclusive use of mist nets. Rev. Biol. Trop. 62 (Suppl. 1): 407-417. Epub 2014 February 01. ; Los inventarios biológicos son esenciales para el seguimiento de cambios causados por factores naturales y antrópicos, y para determinar las prioridades de conservación. El estudio de los murciélagos es importante pues estos proveen servicios ambientales esenciales y su diversidad puede reflejar el estado de otros organismos. Sin embargo, el inventario de los murciélagos del PNN Gorgona puede ser incompleto debido a los pocos muestreos intensivos que se han realizado. En este trabajo, se actualiza el listado de la comunidad de murciélagos del Parque Nacional Natural Gorgona, se evalúa su inventario y se propone una clave taxonómica. Considerando que sólo existe una especie del género Saccopteryx (S. leptura) en Gorgona, en los estudios ...
