Therefore, it is expected that animals make efforts to develop and preserve close social bonds. Reconciliation is a conflict resolution mechanism, which allows buffering the negative effects of aggressive conflict on social relationships. As socioecological theories claim that intrasexual competition and conflict-shaped social interactions among macaque males, postconflict behaviour should reflect the effects of these evolutionary forces. Here, we present the results of a study on a provisioned group of Macaca arctoides in Thailand focusing exclusively on male postconflict behaviour. Through an Information Theory–Model Selection approach, we evaluated the relative support for three predictions about the occurrence of reconciliation and the quality of the opponents' social relationships. The strength of the opponents' affiliative relationship was the only variable predicting reconciliation occurrence. This agrees with the main prediction of the valuable relationship hypothesis for the function and distribution of reconciliation, which states that the opponents sharing high-quality relationships are more likely to reconcile, and this interaction is aimed to repair the disturbing effects of previous aggression on their relationship. The conciliatory tendency found among these wild males is much lower than reported previously for this species from captive conditions, matching more closely the rates reported for species with an intolerant-despotic dominance style. The results offer strong support for the importance of developing and preserving valuable relationships, even among rather intolerant males."],["dc.identifier.doi","10.1111/eth.12034"],["dc.identifier.gro","3151478"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8283"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0179-1613"],["dc.title","Reconciliation in Male Stump-tailed Macaques (Macaca arctoides): Intolerant Males Care for Their Social Relationships"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Socio-ecological models differ in their predictions whether predation risk directly influences feeding competition and which factors exactly predict contest competition. We investigated feeding competition in Siberut macaques (Macaca siberu), a species endemic to Siberut Island (West Sumatra, Indonesia). Siberut macaques experience low predation risk, as major predators (felids, raptors) are absent. They are therefore appropriate subjects to test the prediction that low predation risk reduces feeding competition. To estimate contest potential, we quantified size, spatial distribution and density of food plants, and the availability of alternative resources. We recorded behavior in food patches using a modified focal tree method. Food patches, sorted by decreasing average feeding group size, included large trees (40% of focal plant observations), lianas/strangler (16%), medium trees (9%), small (palm) trees (20%), and rattan (15%). Most food patches were clumped but occurred at low densities relative to the area of average group spread. Thus, availability of alternative food patches was low. Although food patch characteristics indicate high contest potential, the observed aggression rate (0.13 bouts between adults/h) was low relative to other primates. Average feeding group size was small relative to total group size, and feeding group size matched crown volume. Perceived predation risk was low, based on spatial and feeding behavior of juveniles. Together, these results suggest that predation risk may influence feeding competition. Social and temporal factors (patch feeding time), but not ecological factors (fruit abundance in patch and forest, alternative resources) predicted aggression frequency in food patches. Overall, comparative data are still relatively scarce, and researchers should collect more data on group spread, sub-grouping, perceived predation risk, and aggression in food patches before we can draw final conclusions about the role of predation risk for feeding competition."],["dc.identifier.doi","10.1002/ajp.22393"],["dc.identifier.gro","3151488"],["dc.identifier.pmid","25736828"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8294"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0275-2565"],["dc.title","Feeding behavior and aggression in wild Siberut macaques (Macaca siberu) living under low predation risk"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Only few studies showed a reproductive benefit of having more males in a group, and evidence only comes from territorial species, or from species with relatively small male group sizes where males are less prone to suffer from collective action problems. We investigated the effect of male group size on home range size and female reproductive success in a non-territorial species with male dispersal and large male group sizes. Methods: We studied one wild group of Assamese macaques (Macaca assamensis) by following them almost daily (June 2006–September 2012) and collected spatial, behavioral, climate and spatiotemporal data on food plants. Results: Among ecological factors, decreasing rainfall and a statistical interaction between food abundance and distribution were positively related to home range size. After controlling for ecological predictors, we found that male group size but not overall group size had a significant positive effect on full and core home range size. A simple correlation analysis suggests that such an increase in home range area, presumably increasing access to food resources, can be associated with increased female fecundity measured as the proportion or the number of females conceiving in a given year. Discussion: Within the limitations of this study, the results suggest that male resource defense could be a strategy benefitting both sexes if male reproductive skew was low and many males benefited from increased female fertility.
