Anti-predation Strategies on Tent-Making bats
Hearing may be an important sensory modality for detecting predators, particularly in organisms such as bats. To date there is little evidence that predator auditory cues influence the behavior of bats, despite the fact that correct assessment of predation risk, coupled with an adequate behavioral response, should increase survival.
Since bats spend half of their lives in day roosts, predatory events that occur at or near these sites should play a major role in driving their ecology and behavior. My current work examines the response of bats to several predator auditory cues at their diurnal roosts, as well as predator – roost interactions and the effect of habitat disruption on predation.
The study of predators and predation on bats is poorly understood; as a consequence, the importance of this topic has been underestimated on bat conservation. Understanding how the risk of predation drives the behavior of bats on natural habitats, and how predation risk can vary according to habitat degradation, is basic to comprehend the effect of habitat fragmentation and habitat disruption on predator-mediated roost and habitat selection, roost departures, activity and movement patters, and feeding behavior on bats.
