Human vocal folds undergo self-sustaining oscillations during phonation. The phonatory
functions of the vocal folds depend on their mechanical properties. This article presents a …

One major feature of the remarkable vocal repertoires of birds is the range of fundamental
frequencies across species, but also within individual species. This review discusses four …

Males often face a trade-off between investments in precopulatory and postcopulatory traits
[1], particularly when male-male contest competition determines access to mates [2]. To …

Vocal production requires complex planning and coordination of respiratory, laryngeal, and
vocal tract movements, which are incompletely understood in most mammals. Rats produce …

Transforming growth factor (TGF)-β1 and TGF-β3 have been reported to exert differential
effects on wound healing, and possibly even account for tissue-specific differences in scar …

Vocal folds are used as sound sources in various species, but it is unknown how vocal fold
morphologies are optimized for different acoustic objectives. Here we identify two main …

Across vertebrates, progressive changes in vocal behavior during postnatal development
are typically attributed solely to developing neural circuits. How the changing body …

Mate choice is a potent generator of diversity and a fundamental pillar for sexual selection
and evolution. Mate choice is a multistage affair, where complex sensory information and …

In domestic dogs Canis familiaris, vocal traits have been investigated for barks and growls,
and the relationship between individual body size and vocal traits investigated for growls …

The coordination of mammalian physiological and emotional states with the production and
reception of acoustic signals is a product of evolution. Informed by the Polyvagal Theory …
