Vocalizations of anuran amphibians have received much attention in studies of behavioral
ecology and physiology, but also provide informative characters for identifying and …

Extant anuran amphibians originate from an evolutionary intersection eventually leading to
fully terrestrial tetrapods. In many ways, they have to deal with exposure to both terrestrial …

Sound and movement are entangled in animal communication. This is obviously true in the
case of sound-constituting vibratory movements of biological structures which generate …

Zhao et al. recently reported results which, they claim, suggest that sexual selection
produces the multimodal displays seen in little torrent frogs (Amolops torrentis) by co-opting …

Intraspecific communication in frogs plays an important role in the recognition of
conspecifics in general and of potential rivals or mates in particular and therefore with …

Most birds vocalize with an open beak, but vocalization with a closed beak into an inflating
cavity occurs in territorial or courtship displays in disparate species throughout birds. Closed …

Researchers have a natural tendency to classify biological systems into categories. For
example, organisms can be classified based on biome, ecosystem, taxon, phylogeny, niche …

The emergence and maintenance of animal communication systems requires the co-
evolution of signal and receiver. Frogs and toads rely heavily on acoustic communication for …

A common component of divergence in mating behavior is the distinctive mating songs of
insects, and identifying genes underlying natural variation in acoustic behavior is important …
