TLDR
A conceptual framework for testing the relative significance of both adaptive and neutral mechanisms leading to acoustic divergence is summarized, predictions for cases where these processes lead to speciation are predicted, and how their relative importance plays out over evolutionary time are summarized.Abstract:
Acoustic signals mediate mate choice, resource defense, and species recognition in a broad range of taxa. It has been proposed, therefore, that divergence in acoustic signals plays a key role in speciation. Nonetheless, the processes driving divergence of acoustic traits and their consequences in terms of speciation are poorly understood. A review of empirical and comparative studies reveals strong support for a role of sexual selection in acoustic divergence, but the possible concomitant influences of ecological context are rarely examined. We summarize a conceptual framework for testing the relative significance of both adaptive and neutral mechanisms leading to acoustic divergence, predictions for cases where these processes lead to speciation, and how their relative importance plays out over evolutionary time.read more

Baboon vocal repertoires and the evolution of primate vocal diversity.
TL;DR: The findings corroborate the view that the structure of nonhuman primate vocalizations is highly conserved, despite the differences in social systems, and allow for plasticity at the level of the social relationships, mating patterns, and social organization.

The Effect of Timing of Female Vibrational Reply on Male Signalling and Searching Behaviour in the Leafhopper Aphrodes makarovi.
TL;DR: The results show that vibrational duets are tightly coordinated and that the species-specific duet structure plays an important role in mate recognition in location processes.

Divergence of acoustic signals in a widely distributed frog: relevance of inter-male interactions.
TL;DR: In this article, the authors studied the evoked vocal responses of males of three populations of P. thaul in Chile, from northern, central and southern distribution, and found that males of both northern and central populations displayed strong vocal responses when confronted with the synthetic call of their own populations, giving weaker responses to the call of the southern population.

TL;DR: The estimated disparity of acoustic traits was larger than that of morphological traits and the peak in disparity ofoustic traits generally occurred later in the evolution of glassfrogs, indicating a historically recent outset of the acoustic divergence in this clade.

Signals, signal conditions, and the direction of evolution
TL;DR: Sensory systems, signals, signaling behavior, and habitat choice are evolutionarily coupled and should coevolve in predictable directions, determined by environmental biophysics, neurobiology, and the genetics of the suites of traits.
Journal ArticleDOI
Sexual selection, social competition, and speciation
TL;DR: Patterns of variation in socially selected characters demonstrate the wisdom of Darwin's distinction between natural and sexual selection, and the applicability of sexual selection theory to social competition in general.

Ecological Sources of Selection on Avian Sounds
TL;DR: In this article, sound propagation tests were made in forest, edge, and grassland habitats in Panama to quantify pure tone and random noise band sound transmission levels, and the sounds of birds in each habitat were analyzed to determine the emphasized frequency, frequency range, and sound type (whether pure tonelike or highly modulated).

Evidence for Ecological Speciation and Its Alternative
TL;DR: Tests of parallel evolution of reproductive isolation, trait-based assortative mating, and reproductive isolation by active selection have demonstrated that ecological speciation is a common means by which new species arise.

Public information: from nosy neighbors to cultural evolution.
TL;DR: A large body of evidence suggests that human decision-making is strongly influenced by the behavior of others, which may then affect biological evolution.
