Communication

We study communication in lemurs from an evolutionary perspective by examining how sociality influences the complexity of signals. Lemurs represent an excellent example for this research endeavor because they are organized into different social systems ranging from solitary over pair-living to group-living species. We focus thereby on three different aspects: firstly, characterization of the communicative repertoire, secondly we compare the usage and function of signals, as for example alarm or contact calls, in species exhibiting different social systems. Thirdly, we study how phylogenetic descent shapes the structure of signaling systems and which signals, acoustic or visual, are used for species recognition.
