Fig. 2. Hatching response of Agalychnis callidryas embryos to 32 different
temporal patterns of amplitude-matched 0100 Hz white noise bursts
plotted as a function of duty cycle (the ratio of vibration time to total
playback time). Stimuli vary in duration of and intervals between periods of
vibration. Data are mean proportion hatched ± s.e.m. for each stimulus.
For comparison, we have also included the responses to four patterns of
011 kHz noise (open squares) (from
Warkentin, 1995).
