Mate choice can vary in response to internal or external conditions that alter the costs and benefits of being choosy. The relationship between mate choice and hybridization, however, is not well understood. An important influence on mate choice is the rate at which potential mates are...

Mate choice studies most often examine female preferences based on population responses, thus potentially overlooking individual differences in behavior. Moreover, such studies typically use invariant stimulus conditions to infer preferences. By using population responses and static stimulus...

Mating signals that increase attractiveness of males to females can also increase conspicuousness of the signaler to predators and parasites. We investigated the acoustic preference of species of blood-sucking flies of the genus Corethrella (Diptera: Corethrellidae), which eavesdrop on the...

Multispecies choruses represent a promising but uninvestigated forum for public information. Although frogs exposed to a potential predator call more readily in the presence of conspecific calls than in their absence, none are known to make comparable use of heterospecific calls. To test for...

Cricket frogs (Acris crepitans) occupy a variety of acoustically different habitats ranging from pine forest to open grassland. There is geographic variation in their calls and the tuning of their basilar papilla (BP) correlated with habitat. Here, we characterize the spectral content of...

Sexual selection is responsible for the evolution of costly elaborate male traits. When male displays are dynamic, display strategy is sensitive to contextual cues that alter the relative costs and benefits of producing each signal in a male's repertoire. Because females often prefer more...
