Community structure of bats along an altitudinal gradient in tropical eastern Mexico
The changes in species richness, relative abundance, and biomass of bats were monitored along an altitudinal gradient (800 to 2,560 m) in the Sierra Madre Oriental in eastern Mexico. In general, species richness, density, and biomass were correlated with elevation, but the insectivorous bats were more numerous at mid-elevation sites. The frugivorous bats contributed with the majority of the biomass along the gradient. One migratory species (Tadarida brasiliensis) was only detected during the summer months. It is hypothesized that the observed changes are correlated to the amount of food availability and thermoregulatory abilities of bats.
