Habitat use and response to patches of prey by desert insectivorous bats

摘要: I examined the habitat use patterns of an Arizona insectivorous bat community using ultrasonic sensing equipment which allowed field identification species based on their echolocation calls. Response to prey patchiness by encountered was tested ultraviolet lights attract swarms insects. No partitioning or time observed, there being a high degree overlap, and many bats appeared be positively associated. All responded light-induced patches at least some occasions. Analysis populations indicated that food, though abundant, extremely patchy in distribution, both spatially temporally. These data indicate are highly adapted but food source.
