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"]]

Based on captive studies that focus mainly on females, researchers have classified stumptail macaque (Macaca arctoides) social relationships as tolerant, as indicated by a high rate of affiliation, frequent aggression, and symmetrical conflicts. To accumulate more data on male social relationships, which are relatively understudied, and to generate comparative data, we investigated male social relationships in a provisioned group of 68 free-ranging, naturally dispersing stumptail macaques in southern Thailand. We collected continuous focal animal and ad libitum data on 7 adult and 2 subadult males, recording social behavior during 283 contact hours between December 2006 and March 2007. Stumptail macaques of this population were less tolerant than predicted based on previous studies on captive groups: Rates of spatial proximity, affiliation, and aggression were low, most males directed affiliative behavior toward higher-ranking males, and conflicts were generally of low intensity and relatively asymmetrical. Thus, male stumptail macaques of the focal group appear to differ in their social style from a previous study of a captive group that mainly comprised of females. In some traits, they are even more intolerant than rhesus macaques, an intensively studied intolerant macaque species. We also compare our data on stumptail macaque males to those on other male macaques, but available data are too sparse to draw final conclusions."],["dc.identifier.doi","10.1007/s10764-009-9364-z"],["dc.identifier.gro","3151470"],["dc.identifier.pmid","19644554"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11214"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8275"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0164-0291"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Social Relationships in Free-Ranging Male Macaca arctoides"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The present study provides the first detailed and comprehensive ecological data on the Siberut macaque (Macaca siberu), a primate species living exclusively on the island of Siberut off the west coast of Sumatra. Our results show that M. siberu is ecologically similar to its closest relative M. nemestrina occurring on the mainland, both species being semi-terrestrial, mainly frugivorous (75-76%), exhibit a large daily travel distance for their group size and spend more time on traveling than any other macaque species. The habitat of Siberut macaques was floristically very diverse (Simpson’s index D=0.97), although somewhat impoverished in tree species richness, and had a lower tree basal area and a lower rattan density compared to other forests in Malesia (both rattan and palm tree fruit being an important food resource for Macaca siberu due to their long fruiting periods). These factors may lead to a lower diversity and abundance of fruit resources, and coupled with a high degree of frugivory of Siberut macaques, may explain the large amount of traveling observed in this species. The large home range requirements and strong dependence on fruit are important factors that need to be considered when developing conservation measures for this IUCN-listed (Category Vulnerable) species."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2013"],["dc.identifier.doi","10.1186/2193-1801-2-137"],["dc.identifier.gro","3151459"],["dc.identifier.pmid","23724365"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10427"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8262"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","2193-1801"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Ecology of an endemic primate species (Macaca siberu) on Siberut Island, Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["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.
