In the last decade, two hypotheses, one on the evolution of animal vocal communication in
general and the other on the origins of human language, have gained ground. The first …

Otter species are known to fluctuate intraspecifically from a solitary lifestyle to group-living
arrangements. By examining what is known about habitat use and foraging style in otters of …

Unlike the acoustic features of calls, the temporal patterns of call usage in nonhuman
primates are highly flexible. Our recent studies suggest that vocal patterns and species …

Of all the calls made by non-human primates, the function of short-distance contact calls has
largely remained to be determined. These calls are the most frequent in the repertoire and …

Abstract “Conversation rules” such as overlap avoidance and coordinated overlap have
been reported in nonhuman animals, and seem to be adaptive responses to the …

There is no doubt that different factors determine the evolutionary trajectory of a species'
communication abilities. Beyond habitat, social life is likely a selection pressure. The …

Highlights This pilot study shows that wild bonobos display the fundamental temporal rules
of vocal turn-taking Occurrences of calling patterns are in line with the unique observation …

Vocal turn-taking has been described in a diversity of species. Yet a model that captures the
various processes underlying this social behavior across species has not been developed …

A tese está estruturada em três capítulos: o primeiro é uma introdução geral e os dois
seguintes estão organizados como artigos empíricos. A introdução geral traz a definição do …
