Female Rhesus Macaques

Widespread evidence exists that when relatives live together, kinship plays a central role in shaping the evolution of social behaviour. Previous studies showed that female rhesus macaques ( Macaca mulatta ) recognize familiar maternal kin using vocal cues. Recognizing paternal kin might, however, be more difficult as rhesus females mate promiscuously during the possible conception period, most probably concealing paternity. Behavioural observations indicate that semi free-ranging female rhesus macaques prefer to associate with their paternal half-sisters in comparison to unrelated females within the same group, particularly when born within the same age cohort. However, the cues and mechanism/s used in paternal kin discrimination remain under debate. Here, we investigated whether female rhesus macaques use the acoustic modality to discriminate between paternal half-sisters and non-kin, and tested familiarity and phenotype matching as the underlying mechanisms. We found that test females responded more often to calls of paternal half-sisters compared with calls of unrelated females, and that this discrimination ability was independent of the level of familiarity between callers and test females, which provides, to our knowledge, the first evidence for acoustic phenotype matching. Our study strengthens the evidence that female rhesus macaques can recognize their paternal kin, and that vocalizations are used as a cue.

A study was conducted between July 2010 to June 2011 in the Monkey Sterilization Centre, Gopalpur, Himachal Pradesh, India to assess the prevalence of reproductive disorders by laparoscopic examination of the genitalia of female rhesus macaques. The animals were captured from different locations in the state using a cage trapping method. A total of 720 female rhesus macaques underwent laparoscopic examination of their reproductive tracts. A total of 63 cases were found to have reproductive abnormalities. Out of these 63 cases, the most common abnormalities reported were ovarian cyst 3.05% (n=22), ovarian tumor 1.66% (n=12), uterine tumor 1.25% (n=9), uterine edema 0.97% (n=7), uterine rupture 0.83% (n=6), ectopic pregnancy 0.69% (n=5), unicornis or acornis 0.28% (n=2). The highest number of cases of uterine abnormalities was recorded in the 12-16 year old age group (33.33%), followed by 8-12 year olds (25.39%), 16-20 year olds (22.22%), then 4-8 year olds (15.87%) and 0-4 year olds (3.17%). Of the 63 animals that showed genital abnormalities, only 52 were found to be pregnant during the breeding season from November to March in the 5-20 year old age group, while 11 animals were not pregnant; a pregnancy rate of 82.53% (52 of 63) of the female rhesus macaques with reproductive abnormalities.

AbstractThe genetic contributions to sociality are an important research focus for understanding individual variation in social function and risk of social deficits in neurodevelopmental disorders (e.g. autism). The neuropeptide oxytocin (OXT) and its receptor, OXTR, influence social behavior across species. In humans and animals, common variants within the OXTR gene (OXTR) have been associated with varying socio-behavioral traits. However, the reported magnitude of influence of individual variants on complex behavior has been inconsistent. Compared to human studies, non-human primate (NHP) studies in controlled environments have the potential to result in robust effects detectable in relatively small samples. Here we estimate heritability of social behavior and central OXT concentrations in 214 socially-housed adult female rhesus macaques, a species sharing high similarity with humans in genetics, physiology, brain and social complexity. We present a bioinformatically-informed approach for identifying single nucleotide polymorphisms (SNPs) with likely biological relevance. We tested 13 common SNPs in regulatory and coding regions of OXTR for associations with behavior (pro-social, anxiety-like, and aggressive) and OXT concentration in cerebrospinal fluid (CSF). We found moderate rates of heritability for both social behavior and CSF OXT concentrations. No tested SNPs showed significant associations with behaviors or CSF in this sample. Associations between OXT CSF and social behavior were not significant either. SNP effect sizes were generally comparable to those reported in human studies of complex traits. While environmental control and a socio-biological similarity with humans is an advantage of rhesus models for detecting smaller genetic effects, it is insufficient to obviate large sample sizes necessary for appropriate statistical power.

In order to understand the factors that cause and mediate stress in social animals, many studies have examined differences in male physiological stress levels between mating and non-mating seasons, and related these differences to levels of male-male competition. Very few have explicitly tested whether variation in stress levels is related to mating behaviour itself. We provide preliminary evidence of a negative relationship between faecal levels of glucocorticoid metabolites and mounting frequency in free-ranging male rhesus macaques (Macaca mulatta). This finding may help explain the previous observation that male rhesus macaques show no difference in their levels of faecal glucocortocoids between the breeding and non-breeding season, despite the former being associated with elevated levels of aggression. Our study highlights the importance of directly quantifying mating behaviour when investigating the potential impact of reproductive competition and seasonality on stress physiology.
