Whether or not individuals base their immigration strategy on prospective cost-benefit ratios remains unknown. We investigated individual immigration decisions in crested macaques, a primate species with a high reproductive skew in favour of high-ranking males. We found two different strategies. Males who achieved low rank in the new group usually immigrated after another male had immigrated within the previous 25 days and achieved high rank. They never got injured but also had low prospective reproductive success. We assume that these males benefitted from immigrating into a destabilized male hierarchy. Males who achieved high rank in the new group usually immigrated independent of previous immigrations. They recieved injuries more frequently and therefore bore immigration costs. They, however, also had higher reproductive success prospects. We conclude that male crested macaques base their immigration strategy on relative fighting ability and thus potential rank in the new group i.e. potential reproductive benefits, as well as potential costs of injury."],["dc.identifier.doi","10.1038/srep32028"],["dc.identifier.pmid","27535622"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13749"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58749"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","2045-2322"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Determinants of immigration strategies in male crested macaques (Macaca nigra)."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Earlier studies suggested that this population suffered a decline of 75% during 1978-1994. To evaluate its current status we conducted a line transect survey in the Reserve and assessed effects of ecological and anthropogenic variables on macaque abundance and distribution. We estimated a density of 44.9 individuals km(-2) (95% confidence interval, CI, 25.6-78.8) and a total population of 1,951 individuals (CI 1,113-3,421). This estimate of density is 35% lower than that of 68.7 individuals km(-2) in 1994. There were moderate to strong correlations between macaque abundance and vegetation structure (basal area and canopy tree density). We observed illegal logging in the area and therefore habitat quality for macaques may be indirectly affected by illegal human activities. If our population estimate is projected linearly M. nigra could become extinct in Tangkoko within 46 years, highlighting the urgent need to improve management of illegal hunting and logging in the Reserve."],["dc.description.sponsorship","Volkswagen Foundation, Germany; German Research Council (DFG) [EN 719/2]"],["dc.identifier.doi","10.1017/S0030605311000160"],["dc.identifier.isi","000303837100026"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10159"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/26718"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Cambridge Univ Press"],["dc.relation.issn","0030-6053"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Status of, and conservation recommendations for, the Critically Endangered crested black macaque Macaca nigra in Tangkoko, Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
