A few species, however, lack these cues and potentially conceal fertility from males; yet, to date, little is known about mating patterns and their underlying proximate mechanisms in such species. Here, we investigated mating activity and sexual consortships relative to female reproductive state in wild Assamese macaques (Macaca assamensis), a species where females lack prominent anogenital swellings and copulation calls. During two mating seasons (2837 contact hours) we recorded sexual and social behaviors, sexual consortships, and collected 1178 fecal samples (n = 15 females) which were analyzed for progestogen concentrations to assess female reproductive state and to determine the timing of ovulation and conception. Although mostly conceiving in their first ovarian cycle, females were sexually receptive throughout the entire 4-month mating season, and within-cycle mating frequencies were not increased during fertile phases. Dominant males did not monopolize fertile matings, and consortships by high-ranking males lasted for long periods, which were not exclusively linked to female fertile phases. Furthermore, females copulated promiscuously but not randomly, i.e. for almost every female, matings were concentrated to a certain male, irrespective of male rank. Collectively, we demonstrate that fertility is undisclosed to males. The extreme extended female sexuality facilitated by concealed fertility may allow females to create differentiated mating relationships within a promiscuous mating system. Our study provides important new insight into the plasticity of female sexuality in non-human primates."],["dc.identifier.doi","10.1371/journal.pone.0023105"],["dc.identifier.gro","3151464"],["dc.identifier.pmid","21853074"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8336"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8268"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.title","Concealed Fertility and Extended Female Sexuality in a Non-Human Primate (Macaca assamensis)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Here, we report 4 yr of data on reproductive and life-history traits for wild female Assamese macaques (Macaca assamensis) at Phu Khieo Wildlife Sanctuary, northeastern Thailand. During 2 consecutive reproductive seasons, we investigated reproductive behavior and sexual swelling size in 16 females and collected 1832 fecal samples. Using enzyme immunoassays, we measured fecal estrogen and progesterone metabolites to assess ovarian activity and timing of ovulation and to ascertain conceptions and pregnancies. Timing of reproduction was strictly seasonal (births: April–July, 86% in April–June, 4 yr, n = 29; conceptions: October–February, 65% in December–January, 2 yr, n = 17). Females showed no cyclic ovarian activity outside the mating season and conceived in their first or second cycle (mean: 1.2 cycles to conception, n = 13). Gestation length was on average 164.2 d (range: 158–170, n = 10), and females had their first infant at an age of 5 yr (n = 4). Interbirth intervals were bimodally distributed, with females giving birth on average every 13.9 or 23.2 mo. Shorter interbirth intervals were linked to early parturition within the birth season. Most females displayed subcaudal sexual swellings which, however, did not reliably indicate female reproductive status or fertility.

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"]]

Mating with many males, however, requires a low female monopolizability, which is affected by the spatiotemporal distribution of receptive females. Ovarian cycle synchrony potentially promotes overlapping receptivity if fertile and receptive periods are tightly linked. In primates, however, mating is often decoupled from hormonal control, hence reducing the need for synchronizing ovarian events. Here, we test the alternative hypothesis that females behaviorally coordinate their receptivity while simultaneously investigating ovarian cycle synchrony in wild, seasonal Assamese macaques (Macaca assamensis), a promiscuous species with extremely extended female sexuality. Using fecal hormone analysis to assess ovarian activity we show that fertile phases are randomly distributed, and that dyadic spatial proximity does not affect their distribution. We present evidence for mating synchrony, i.e., the occurrence of the females' receptivity was significantly associated with the proportion of other females mating on a given day. Our results suggest social facilitation of mating synchrony, which explains (i) the high number of simultaneously receptive females, and (ii) the low male mating skew in this species. Active mating synchronization may serve to enhance the benefits of extended female sexuality, and may proximately explain its patterning and maintenance."],["dc.identifier.doi","10.1371/journal.pone.0026144"],["dc.identifier.gro","3151447"],["dc.identifier.pmid","22022541"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8341"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8249"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.title","You Mate, I Mate: Macaque Females Synchronize Sex not Cycles"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["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"]]
