Diversidad de murciélagos (Mammalia: Chiroptera) asociados a un gradiente altitudinal al sur del Ecuador (Estación Científica San Francisco, Zamora Chinchipe)

Abstract

Abstract: The order Chiroptera is one of the most diverse groups of mammals in Ecuador, with more than 180 species that play important ecological roles. Multiple species have been recorded at the San Francisco Research Station (SFRS). Due to its location, the SFSRS is considered a diversity hotspot. This study aims to determine the species richness of bats along an altitudinal gradient in the SFSRS, analyze variations in composition, and determine whether they are correlated with altitudinal changes. Mist nets were used, with sampling stations active from 6:00 PM to midnight. The results include 112 records, corresponding to three families and 31 species, 10 of which are new records for the SFSRS. Despite the sampling effort, no specimens were captured at high altitudes, demonstrating an influence of altitude on species diversity. However, no statistically significant differences in community composition were detected between ecosystems. This research is crucial for understanding these ecosystems and establishing conservation strategies.
