Mist nets set at ground level is the traditional method of surveying bats and in Amazon, almost half bat surveys used this methodology. The sole use ground-level mist biases because lack records aerial insectivorous bats, which forage above canopy or other open areas. Canopy nets, roost searches acoustic are methods to survey assemblages, but their efficiency compared has not been fully evaluated world's largest tropical rainforest. Here, we test how complementarity sampling contributes number species recorded Amazonian We simultaneously sampled using ultrasonic recorders Ducke Reserve (Central Amazon) Brazil did a literature review conducted Amazon assess these have field research during recent decades.
