摘　　要：Male signaling influences both female choice and male-male competition. Although male signaling characteristics and female preferences have been shown to coevolve in many species, few studies have examined whether male signal characteristics and male receiver responses related to male-male competition also coevolve. The present study tested the hypothesis that male and female signal receiver preferences may coevolve in parallel for flogs in the genus Babina by comparing the acoustic structure of male advertisement calls of four closely related and geographically isolated Babina species. Then we assessed the behavioral responses of both male and female B. daunchina （Emei music frog） to male call playbacks from each of the four species. The results support the hypothesis that male and female signal receiver preferences have coevolved in this species. Specifically, both male and female B. daunchina respond strongly to the heterospecific calls of B. hainanensis, suggesting that preexisting biases exist in both females and males. Both male and female individuals showed a slight response to the calls of B. adenopleura while no response was evoked by the calls ofB. lini. The manifestation of similar response profiles in male and female B. daunchina to the calls of the four species support the idea that male and female signal receiver preferences evolved in parallel and that the origin of these receiver biases reflects adaptations dependent on the same neural and cognitive systems in both sexes.Male signaling influences both female choice and male-male competition.
