Why animal communication displays are so complex and how they have evolved are active
foci of research with a long and rich history. Progress towards an evolutionary analysis of …

Undeniably, acoustic signals are the predominant mode of communication in frogs and
toads. Acoustically active species are found throughout the vast diversity of anuran families …

High background noise is an impediment to signal detection and perception. We report the
use of multiple solutions to improve signal perception in the acoustic and visual modality by …

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 …

An animal's behavioral phenotype comprises several traits, which are hierarchically
structured in functional units. This is manifested in measured behaviors often being …

Where they co-occur, male anurans of different species may signal from diverse locations
and use vocalizations that differ spectrally. However, the relevance of such differences to the …

Long‐distance acoustic signals are widely used in animal communication systems and, in
many cases, are essential for reproduction. The acoustic adaptation hypothesis (AAH) …

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 …

Although acoustic signals are important for communication in many taxa, signal propagation
is affected by environmental properties. Strong environmental constraints should drive call …

Animal communication is often hampered by noise interference. Noise masking has
primarily been studied in terms of its unimodal effect on sound information provision and …
