Resumen

The combined use of different methods for surveying bat assemblages has increased over the last few
decades. The objective of this study was to assess the efficiency of bat inventories by comparing assemblages parameters
(species richness, abundance and composition) using the 3 most conventional capture methods (ground-level and
sub-canopy mist nets and harp traps), in a lowland tropical dry forest in Yucatán, Mexico. In ground mist nets, only
phyllostomid species were recorded, principally frugivorous and nectarivorous species, while in harp traps the majority
were insectivorous species from other families. Our results indicate that for the order Chiroptera the most efficient
combination of capture methods is the simultaneous use of ground mist nets and harp traps. However, an inventory of
Phyllostomidae is reliably achieved with only ground mist nets. Also, a combination of ground and sub-canopy mist
nets does not provide an efficient sampling strategy.
