Research interest

My PhD project focuses on the functions of a long-distance signal in orangutans, the so called long call.
The aim of the project is to explain the social organization of orangutans through a detailed study of their long-distance communication system using autonomous auditory monitoring AAM (several recorders placed in a grid of 3 km2) in combination with traditional behavioral data collection.

I explicitly investigate this communication system in the context of a large and fluid social network comprising several individuals of different age-sex classes that may be both intended and unintended (eavesdropping) receivers of the information content encoded in male orangutans’ long calls.
