The power of sound: unravelling how acoustic communication shapes group dynamics
Acoustic signalling is a key mode of communication owing to its instantaneousness and rapid turnover, its saliency and flexibility and ...
Exploring the role of vocalizations in regulating group dynamics
Because of the diverging needs of individuals, group life can lead to disputes and competition, but it also has many advantages, such a...
A scoping review of the use of bioacoustics to assess various components of farm animal welfare
Recording and analyzing animal sounds, including vocal and non-vocal cues, is a relevant tool to access and monitor different aspects o...
The role of neighbour proximity and context on meerkat close call acoustic structure
In many animal species, including humans, producer arousal state is considered a key modifier of vocal production and structure. Encodi...
