Owing to their slow life histories and challenging social conditions, determination of maternal androgens and potential interference effects of fetal androgen production are of particular interest in wild primates. However, androgen production has been rarely investigated in wild female primates, and studies on maternal androgens during gestation in particular often do not span the entire pregnancy. Here, we characterize fecal androgen production throughout gestation in wild Assamese macaques (Macaca assamensis) using noninvasive hormone analysis and, furthermore, examine fetal sex effects on maternal androgen excretion. A total of 207 fecal samples were analyzed from seven females for concentrations of immunoreactive epiandrosterone (iEA). Fecal iEA concentrations, as predicted based on cercopithecine blood-serum patterns, increased during early gestation and were significantly higher during the first trimester compared with preconception concentrations and those recorded during later stages of gestation. Further, during the third trimester, male-carrying mothers showed significantly higher iEA concentrations compared with female-carrying mothers. This first characterization of fecal androgen excretion during gestation in Assamese macaques indicates both a maternal and fetal effect on androgen production. Although our sample size is small, our results, nevertheless, provide the basis for assessing potential influences of maternal androgens on postnatal offspring development and behavior."],["dc.identifier.doi","10.1002/ajpa.21646"],["dc.identifier.gro","3151471"],["dc.identifier.pmid","22183710"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8276"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0002-9483"],["dc.title","Brief communication: Fecal androgen excretion and fetal sex effects during gestation in wild assamese macaques (Macaca assamensis)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Positive social interactions are particularly important for females of species living in complex societies, e.g. humans and non-human primates. Existing studies have mainly focussed on the effect of same-sex social interaction on the stress response, rather than both same- and opposite-sex social interaction simultaneously. However, consideration of both may be crucial since females may have different ‘social needs’ across different life-history stages. Applying the conceptual framework of allostasis, we tested the hypothesis that female allostatic load (measured through faecal glucocorticoid levels [fGCs]), of wild seasonally breeding Assamese macaques (Macaca assamensis), would increase if their social needs were not maintained in accordance with season. We found significant seasonal differences in same- and opposite-sex sociality which, depending on season, predicted female fGCs. In the mating season, females which spent more time close to males and more frequently groomed with them exhibited lower fGCs. In the non-mating season, when female–male interaction was infrequent, positive female–female sociality predicted lower fGCs. Our results support the hypothesis that same- and opposite-sex sociopositive interactions, specific to certain life-history stages, can mediate fGCs. We interpret this as a consequence of the positive direct and/or indirect effects of social contact in accordance with interactions pertaining to a given life-history stage, which are likely to impact positively upon fitness."],["dc.identifier.doi","10.1016/j.psyneuen.2014.05.022"],["dc.identifier.gro","3151442"],["dc.identifier.pmid","24980035"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8244"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0306-4530"],["dc.title","Low female stress hormone levels are predicted by same- or opposite-sex sociality depending on season in wild Assamese macaques"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Across 2 years, 155 fecal samples were collected from seven reproductively quiescent (i.e., acyclic) females during the premating season months, August and September. Samples were analyzed for immunoreactive epiandrosterone (iEA), a major fecal metabolite of testosterone in macaques. Changes in iEA concentrations during the premating season were significantly negatively associated with (1) the presence of dependent offspring, i.e., lactating females showed a smaller change, and (2) with the timing of conceptions in the mating seasons, i.e., females that conceived early exhibited the greatest changes.
