Nest grouping patterns of bonobos (Pan paniscus) in relation to fruit availability in a forest-savannah mosaic.

A topic of major interest in socio-ecology is the comparison of chimpanzees and bonobos' grouping patterns. Numerous studies have highlighted the impact of social and environmental factors on the different evolution in group cohesion seen in these sister species. We are still lacking, however,...
