Condition dependence in the sexual communication system of the Tungara frog

Sexual selection can result in the evolution of extreme armaments and ornaments, and the development and maintenance of these traits can come at a considerable cost. These costs have been implicated in enforcing an upper limit on trait divergence and promoting condition-dependent traits such that only individuals in sufficiently high condition can effectively wield these armaments and advertise these ornaments. Numerous studies demonstrate the condition-dependence of sexually selected traits, especially those used by males to advertise to females. In this study, we investigated condition-dependent mating calls in the túngara frog Physalaemus (Engystomops) pustulosus. We manipulated male condition in the laboratory over a nine-day period by restricting food availability. We then documented the relationship between male condition (the relative change in body mass from night 1 to night 9) and acoustic parameters of his mating call; how male condition influenced the male’s responses to call..., , , # Condition Dependence in the Sexual Communication System of the Tungara frog
