A prominent hypothesis states that coalitions may be under cognitive constraints, but this idea is debated and remains to be tested empirically. In this study, we evaluate the cognitive constraint hypothesis against 3 alternative hypotheses that stress the role of demography, substrate use, and resource competition, for the evolution of male coalitions. A comparative analysis of a unique data set of 86 multimale multifemale groups of 38 nonhuman primate species from all major radiations revealed no evolutionary association of male coalition frequency with cognitive capacity (as indexed by neocortex ratio and endocranial volume). The observed variation was best explained by demography and resource competition in that male coalitions were more likely to occur in species characterized by larger male groups and reduced levels of contest competition (after controlling for phylogeny). These findings suggest that constraints imposed by the socioecological setting, rather than cognition, explain best why some primate species evolved customary coalitionary behavior while others did not. This study presents the first empirical evidence against the long-standing view that cognitive abilities may impose a limit on the use of coalitions in animals."],["dc.identifier.doi","10.1093/beheco/aru054"],["dc.identifier.gro","3151482"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8288"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1045-2249"],["dc.title","Socioecology, but not cognition, predicts male coalitions across primates"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Although heterosexual friendships have been described in baboons, these are short-term affairs serving as protection against infanticide and thus tightly linked to the presence of vulnerable infants. Long-term association may be adaptive in situations of low male monopolization potential where it pays to invest in a particular female partner instead of spreading the effort among many females. Using long-term data, we investigated male–female and male–infant associations in wild Assamese macaques, Macaca assamensis. Group-wide and individual male–female associations were stable for at least 2 or 3 years. Association during the mating season but not before the mating season predicted male mating success, lending support to the ‘friends with benefits’ but not the ‘mating effort’ hypothesis. Mating success in turn predicted male–female association at birth as well as male–infant association before weaning. In support of the ‘paternal care hypothesis’ paternity was an independent predictor of male–infant association beyond weaning age, creating potential for true paternal care. We thus postulate that particular demographic and life history circumstances may favour male–female friendships by creating a positive feedback between male–female–infant associations driven by paternal care and male–female associations promoted by increased mating access to drive the evolution of long-term male–female bonds."],["dc.identifier.doi","10.1016/j.anbehav.2013.07.004"],["dc.identifier.gro","3151502"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8306"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0003-3472"],["dc.title","Stable heterosexual associations in a promiscuous primate"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
