Isabelle Charrier Team

Acoustic Communications

In brief

Our team is dedicated to the study the animal vocal communication with comparative and evolutionary approaches, using a multi-disciplinary methodology. We investigate how animals use their vocalizations to organize their social activities, the mechanisms of vocal production, the strategies of communications in regards to both social and physical constraints, but we also used acoustic to survey the biodiversity and monitor species populations.

Our research

Several research topics are developed including:
• 1) Dynamics of vocal activity and social network
• 2) Vocal production modelling
• 3) Communciation strategies in regards to social and physical constraints
• 4) Female singing behaviour
