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

TL;DR: It is shown that small-sized frogs often emit calls with frequency components in the ultrasound spectrum, although it is unlikely that these high frequencies are of biological relevance for the majority of them, and it is illustrated that detection of upper harmonics depends also on recording distance because higher frequencies are attenuated more strongly.

Terrestrial Passive Acoustic Monitoring: Review and Perspectives
Larissa Sayuri Moreira Sugai,Larissa Sayuri Moreira Sugai,Thiago Sanna Freire Silva,José Wagner Ribeiro,Diego Llusia,Diego Llusia +5 more
TL;DR: Passive acoustic monitoring (PAM) is quickly gaining ground in ecological research, following global trends toward automated data collection and big data as mentioned in this paper, using unattended sound recording, PAM provides tools for longterm and cost-effective biodiversity monitoring.

TL;DR: It is shown that elevated levels of sexual selection are associated with more rapid phenotypic divergence between related lineages, and that this effect is restricted to male plumage traits proposed to function in mate choice and species recognition.

TL;DR: How sexual selection and natural selection are different mechanisms of evolutionary change is outlined, and it is suggested that this distinction is critical when analyzing the role of sexual selection in speciation.

TL;DR: A review of the terminology and variation of frog calls from a perspective of integrative taxonomy can be found in this paper, where the authors provide guidelines for the taxonomic interpretation of advertisement call differences in sympatric and allopatric situations.

Neural Constraints on the Complexity of Avian Song
TL;DR: Evidence that females may do so because male song can be an honest indicator of attributes of a male’s brain that could contribute to his fitness or that of his young is reviewed.

Independent cultural evolution of two song traditions in the chestnut-sided warbler.
TL;DR: It is found that the species’ two song categories form two distinct cultural traditions, each with its own pattern of change over time, which indicates that in songbirds, multiple independent cultural traditions and probably multiple independent learning predispositions can evolve concurrently.

A signal-substrate match in the substrate-borne component of a multimodal courtship display
TL;DR: The results confirm the importance of sub- strate-borne signaling in S. stridulans and suggest a match between signal properties and signal efficacy - leaf litter transmits the signal most effectively and males are most successful in obtaining copulations on leaf litter.

Male song structure predicts reproductive success in a wild zebra finch population

TL;DR: Differences in male song can predict differences in reproductive success in the zebra finch, and it is suggested that differences in genetic quality are responsible, rather than differences in parental care or maternal investment in the eggs.

Local song elements indicate local genotypes and predict physiological condition in song sparrows Melospiza melodia
TL;DR: Syllable sharing in migratory song sparrows was correlated with genetic similarity to the local population, suggesting that song reflects population of origin and females preferring ‘local-sounding’ males may obtain genetic and/or direct benefits for their offspring.
