Frogs Call at a Higher Pitch in Traffic Noise
Male frogs call to attract females for mating and to defend territories from rival males. Female frogs of some species prefer lower-pitched calls, which indicate larger, more experienced males. Acoustic interference occurs when background noise reduces the active distance or the distance over which an acoustic signal can be detected. Birds are known to call […]
Consequences of Compensatory Growth in an Amphibian
Compensatory growth, or catch-up growth, occurs when an organism grows faster than the optimal rate after a period of growth restriction. The evolved optimal growth rate maximizes an animal’s fitness potential while preserving tissue quality. Rapid compensatory growth allows the organism to achieve an adult size closer to that of an unrestricted conspecific. However, this […]
