The Sounds of Silence as an Alarm Cue in Túngara Frogs, Physalaemus pustulosus

摘要: In many species males vocally advertise for mates in choruses and these serve as acoustic beacons to conspecific females well eavesdropping predators parasites. Chorusing will often cease response disturbances, such the presence of predators. some cases cessation is so rapid over a large area that it seems improbable are all responding directly same local disturbance. Here, we demonstrate experimentally Neotropical tungara frogs, Physalaemus pustulosus, calling by spreads rapidly through chorus. The chorusing playbacks three more effective inducing chorus than one male calling. When calling, complex calls simple calls. There no main effect on whether final call complete or interrupted. We thus conclude sudden lack signals—the 'sounds silence'—becomes an alarm cue can explain common species. Abstract Spanish available at http://www.blackwell-synergy.com/loi/btp.
