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.

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.

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.

Chapter 6 – Singing in the wild: the ecology of birdsong
TL;DR: In this article, the authors focus on the habitat as a source of selection pressures on sound signals, and consider how sound changes when radiating from sender to receiver as a function of habitat characteristics, and how sound perception is affected by ambient noise that varies with habitat and the animals that live there.

TL;DR: Habitat-dependent divergence in songs within species potentially plays an important role in ecological speciation through its impact on species recognition and mate choice and factors related to climate, vegetation, and vocal community can promote such habitat-dependent song variation.

Environmental and Biological Constraints for the Evolution of Long-Range Signalling and Hearing in Acoustic Insects
TL;DR: It is suggested that the evolutionary past may represent a constraint on the communication system, where conservative features of the sensory and nervous system would now appear to be maladaptive for intraspecific communication.
