Abstract: The competitive regime faced by individuals is fundamental to modelling the evolution of social organisation. In this paper, we assess the relative importance of contest and scramble food competition on the social dynamics of a provisioned semifree-ranging Cebus apella group (n= 18). Individuals competed directly for provisioned and clumped foods. Effects of indirect competition were apparent with individuals foraging in different areas and with increased group dispersion during periods of low food abundance. We suggest that both forms of competition can act simultaneously and to some extent synergistically in their influence on social dynamics; the combination of social and ecological opportunities for competition and how those opportunities are exploited both influence the nature of the relationships within social groups of primates as well as underlying the evolved social structure.
