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

Environmental influences on acoustic divergence in Rhinolophus bats of the Western Ghats-Sri Lanka region
TL;DR: The variable but significant influences of humidity and correlated factors on RF suggest the importance of environmentally mediated acoustic divergence in different Rhinolophus species in the WGSL.

Geographic variability in the alarm calls of the European ground squirrel.
TL;DR: There is a rather substantial geographic variability in the alarm calls of the European ground squirrel, and this study highlights its possible impact on conservation measures such as establishing artificial colonies or reintroductions.

Convergent character displacement in sympatric tamarin calls (Saguinus spp.)

TL;DR: Though their long calls asymmetrically converged in sympatry, only red-handed tamarins shifted towards pied tamarin call type, and this only occurred in primary forest, which suggests that both social and environmental pressures are important in shaping primate calls.

Fish acoustic community structure in Neptune seagrass meadows across the Mediterranean basin
Marta Bolgan,Lucia Di Iorio,Thanos Dailianis,Ignacio Alberto Catalán,Pierre Lejeune,Marta Picciulin,Eric Parmentier +6 more
TL;DR: In this article , the authors investigated the structure, organization and variability of fish sounds at the community level and showed that the degree of acoustic niche plasticity might be determined by the species-specific degree of sound-producing system plasticity.

Acoustic signalling in Orthoptera
Marion Hall,David Robinson +1 more
TL;DR: For most species, acoustic signalling is the most important means of communication and plays a vital role in mating, mate choice, intrasexual competition, interspecific interactions with predators and parasitoids, and the divergence of populations and species as discussed by the authors.

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.
