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 …

Animals use acoustic signals for communication, implying that the properties of these
signals can be under strong selection. The acoustic adaptation hypothesis predicts that …

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

Environmental differences influence the evolutionary divergence of mating signals through
selection acting either directly on signal transmission (“sensory drive”) or because …

While morphological traits are often associated with multiple functions, it remains unclear
how evolution balances the selective effects of different functions. Birds' beaks function not …

Whether listening in a forest or on an open plain, by the side of a river or in the ocean, at the
outskirts of suburbia or right downtown, the Earth abounds with sounds. The use of the term …

Studying macroevolutionary patterns of phenotypic variation and their driving forces in large
radiations can shed light on how biodiversity is generated across broad spatiotemporal …

Competition between closely related species has long been viewed as a powerful selective
force that drives trait diversification, thereby generating phenotypic diversity over …

Birds singing in choruses must contend with the possibility of interfering with each other's
songs, but not all species will interfere with each other to the same extent due to signal …

Studying the macroevolution of the songs of Passeriformes (perching birds) has proved
challenging. The complexity of the task stems not just from the macroevolutionary and …
