Evolutionary divergence in acoustic signals: causes and consequences
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

Acoustic communication in marine shallow waters: testing the acoustic adaptive hypothesis in sand gobies.
Maria Clara Pessoa Amorim,Raquel O. Vasconcelos,Marta Bolgan,Silvia S. Pedroso,Paulo J. Fonseca +4 more
TL;DR: The data demonstrate that the hearing abilities of these gobies are well suited to detect conspecific sounds within typical interacting distances (a few body lengths) in Atlantic shallow waters, lending support to the acoustic adaptive hypothesis, proposing that signals and perception systems coevolve to be effective within local environment constraints.

The theory of island biogeography and soundscapes: Species diversity and the organization of acoustic communities
Aloïs Robert,Thierry Lengagne,Martim Melo,Vanessa Gardette,Sacha Julien,Rita Covas,Doris Gomez,Claire Doutrelant,Claire Doutrelant +8 more
TL;DR: In this paper, the authors compared two pairs of insular and continental soundscapes: one in a temperate zone, the other in the tropics, and assessed acoustic niche organization by computing, for each community, species turnover, temporal and frequency overlaps, and acoustic avoidance.

Phenotypic variation and covariation indicate high evolvability of acoustic communication in crickets.
TL;DR: The observed genetic architecture does not suggest rapid divergence, although sex linkage may have allowed for somewhat higher evolutionary rates, and P matrices revealed that multivariate variation in song traits aligned with major dimensions in song preferences, suggesting a strong selection response.

Individuality in the vocalizations of infant and adult coppery titi monkeys (Plecturocebus cupreus).
TL;DR: It is shown that pulse‐chirps of adult titi monkey duets are individually distinct, and infant trills are lessividually distinct, which may be due to the different functions of the vocalizations.

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.

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.
