Challenges to Female Reproduction and Survival in Wild Primates

Research on geladas (Theropithecus gelada) in Simien National Park, Ethiopia, reveals that low social rank and primiparity pose significant energetic challenges for female primates. These factors increase glucocorticoid (GC) levels during gestation, delay weaning, and slow maternal reproductive pace, potentially impacting offspring development long-term. Additionally, the study found that a stronger hypothalamic-pituitary-adrenal (HPA) axis response in white-faced capuchins (Cebus imitator) correlates with higher survival probabilities when facing deadly challenges, suggesting an adaptive role of the HPA axis in prioritizing immediate survival. The research combines data from long-term primate studies to examine GC responses to energetic challenges alongside measures of reproductive success and survival.
