Abstract:Acoustic signals mediate a variety of life history events in animals, such as resource competition, mate selection, and antipredator defense. Therefore, it has been proposed that acoustic signals have profound effects on population stability and community dynamics. Echolocating bats occupy a nocturnal niche in the sky. They have comparatively poor eyesight but well-developed hearing, providing a good model for acoustic research. In this review we summarize the current studies regarding the function of echolocation and social calls in bats. We provide some recommendations and directions for future work. Analysis of the published literature shows that echolocation calls of bats serve multiple functions, including spatial orientation, prey tracking, recognition of water and plant, foraging coordination, and social information transfer. In contrast, bats employ social calls to engage in social activities, namely social contact, resource competition, mate choice, and distress calling. Despite the majority of studies have focused on echolocation calls, it is only recently that attention has been directed to the function of social calls in bats. Further work is warranted to explore the mechanisms underlying the production of acoustic signals among bats.
