The Role of Vibration Amplitude in the Escape-Hatching Response of Red-Eyed Treefrog Embryos.

ABSTRACT: The function and adaptive significance of defensive behaviors depend on the contexts in which they naturally occur. Amplitude properties of predator cues are widely used by prey to assess predation risk, yet rarely studied in the context of the stimuli relevant to defensive decisions in nature. Red-eyed treefrog embryos, Agalychnis callidryas, hatch precociously in response to attacks on their arboreal egg clutches by snakes and wasps. They use vibrations excited during attacks to detect predators, but wind and rainstorms also excite intense vibrations. Past work has demonstrated that to avoid costly decision errors, A. callidryas nonredundantly combine information from the temporal and frequency properties of clutch vibrations. Here, we demonstrate that embryos also use abso
