IPS title

Primate socio-ecology is rooted in modern behavioral ecology and sets out to illuminate the adaptive bases of variation in grouping patterns, mating systems and social relationships between individuals. We aim to identify evolutionary rules for the development and expression of power asymmetries, coalition formation and conflict management. In short we want to know why some primates are always nice and even empathic, whereas others are nasty, rude and unable to apologize.

The Integrative Primate Socio-Ecology Group (IPSE) is closely affiliated with the Primatology Department and shares methods, thoughts and resources with its members. IPSE rests on three pillars: conceptual (more), theoretical (more) and empirical work (more). It integrates (1) primates from all lineages (old world, neotropical and prosimian primates), (2) data from both the wild and captive settings, (3) original data and meta-analyses of published information, (4) physiological, genetic and behavioral methods, and (5) the evolution of male social relationships and ecological constraints on males into the socioecological model.
