Animals produce a wide array of sounds with highly variable acoustic structures. It is
possible to understand the causes and consequences of this variation across taxa with …

Animal acoustic communication is one of the most fruitful research areas in behavioural and
evolutionary biology. Work in this area depends largely on quantifying the structure of …

Phenotypic divergence can promote reproductive isolation and speciation, suggesting a
possible link between rates of phenotypic evolution and the tempo of speciation at multiple …

Vocal learning has evolved independently in several lineages. This complex cognitive trait is
commonly treated as binary: species either possess or lack it. This view has been a useful …

Some animal vocalizations develop reliably in the absence of relevant experience, but an
intriguing subset of animal vocalizations is learned: they require acoustic models during …

The study of animal acoustic signals is a central tool for many fields in ecology and
evolution, but the diversity of analytical methods and sources of animal sound recordings …

Sexual signals are archetypes of contingent evolution: hyper-diverse across species, often
evolving fast and in unpredictable directions. It is unclear to which extent their evolutionary …

Acoustic indices derived from environmental soundscape recordings are being used to
monitor ecosystem health and vocal animal biodiversity. Soundscape data can quickly …

Morphology, habitat and various selective pressures (eg social and sexual selection) can
influence the evolution of acoustic signals, but the relative importance of their effects is not …

Much ecological and evolutionary theory predicts that interspecific interactions often drive
phenotypic diversification and that species phenotypes in turn influence species …
