摘要:

We tested the hypothesis that acoustic stimuli must be similar to the species-typical advertisement call in both dominant frequency and pulse rate to attract female Woodhouse's toads (Bufo woodhousei) in discrimination trials. Using synthetic advertisement calls we determined that females always preferred a synthetic call with the species-specific pulse rate and frequency over synthetic calls in which only pulse rate or frequency was within the range for the species. However, appropriately pulsed, narrow-band filtered noise was a sufficient acoustic stimulus to attract 20% of the females in one-quarter of their discrimination trials. These results are discussed in light of species recognition in bufonids.
