Intra-specific variation in the social organisation of old world monkeys and apes

Project summary
Many species are specialised in their social organisation, for example baboons and chimpanzees always living in multi-male multi-female groups. However, it has been realised that in many other species intra-specific variation in social organisation (IVSO: variation in group composition) exists. In collaboration with Loren Hayes from the University of Tennessee at Chattanooga (USA), we are working on a database of all mammalian species, collecting data on intra-specific variation in social organisation. In the current project, a student will work on old world (Africa and Asia) primates and apes to identify specialised and variable species. Furthermore, data will be gathered on which mechanism might have led to IVSO.

Database data entry: The student will search for primary literature of field studies reporting the social organisation of old world monkeys and apes. The student will use specific search rules that have been developed by Hayes and Schradin and record into the database all forms of social organisation that have been reported per species, the number of field studies, and additional crucial information.
Review of original studies: For all primate species where IVSO has been identified, the student will go through the primary literature of these field studies and collect information that will enable us to differentiate between the four mechanisms that can lead to IVSO (Schradin 2013). Specifically, the student will test the hypotheses that IVSO is most common in species that typically living in family groups with one socially monogamous breeding pair.
