TL;DR: It is reported that physical attacks by a territorial male are provoked only in response to dynamic bimodal stimuli in which the acoustic playback of vocalizations is coupled with vocal sac pulsations, but not by either unimodal cues presented in isolation or static bimmodal stimuli.

TL;DR: The acoustic behaviour of 15 sympatric and synchronically breeding species of frogs in an area of floating meadows near Manaus (Brazil) was studied for a period of 8 months to study the mating calls of these species.

TL;DR: It is demonstrated that temporal and spatial integration may be reliably estimated in a freely behaving animal in its natural habitat and that aggressive behavior in this species can be used as an index of cross-modal integration in the field.

TL;DR: The discrepancy in PRRs between the sexes due to differences in parental investment and the prolonged breeding season is sufficient to explain the observed mating pattern i.e., selective females, high variance in male mating success, and the considerable opportunity for sexual selection.

TL;DR: The results obtained depict a complex evolutionary scenario and emphasize the importance of considering multiple traits when disentangling the forces behind allopatric divergence in the Amazonian frog, Allobates femoralis.
