Semantic content in titi monkey alarm call sequences

Berthet, Mélissa ; Zuberbühler, Klaus (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

The comparative approach aims to understand the uniqueness of human language and how it evolved from primitive communication systems. Black-fronted titi monkeys Callicebus nigrifrons possess two soft alarm calls: A-calls are specific to threats within the canopy while B-calls are general calls emitted to terrestrial predators but also in non-predatory contexts, while moving near the...

Object manipulation and tool use in a community of wild chimpanzees ("Pan troglodytes schweinfurthii") of the Budongo Forest, Uganda

Lamon, Noémie ; Zuberbühler, Klaus (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

This thesis examines wild chimpanzee tool use, with a particular focus on the ontogeny of object manipulation, as well as transmission mechanisms and possibility of cultural evolution of tool use in this species. Chimpanzees are known for their tool use proficiency and have been extensively studied regarding these skills. Previous studies on the ontogeny of tool use have focused on the...

Courtship communication in the wild chimpanzees of Budongo, Uganda

Fallon, Brittany Laurie Ann ; Zuberbühler, Klaus (Dir.) ; Byrne, Richard (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

This thesis examines wild chimpanzee mating behaviour, and considers in particular the role of communication during mating. Previous studies have focused on compiling behavioural ethograms, or on a small subset of courtship signals. More generally, research on chimpanzee sexual behaviour has rarely looked at intentional communication, but instead focused on a handful of courtship tactics, such as...
