Fission-fusion dynamics: costs and consequences of fissioning and fusing in spider monkeys
ContextIn some animals, the social group splits up into subgroups on a regular basis. This fluid grouping system allows animals to deal with food competition within the community yet still aggregate during times when aggregation is most favourable. Fission-fusion may have played an important role in early human evolution. ApproachI work together with Dr Filippo Aureli, Liverpool John Moores’ University, and Dr Colleen Schaffner, University of Chester, who run a field project collecting data on all aspects of behaviour and ecology of spider monkeys in Santa Rosa National Park, Costa Rica. Dr Norberto Asensio did recent field work at that site. PublicationsKorstjens, AH, RH Layton, CP van Schaik, C Boesch, & RIM Dunbar (forthcoming).
