  • Physical, behavioral, and hormonal changes in the resumption of sexual receptivity during postpartum infertility in female bonobos at Wamba

    Open Access•Chie Hashimoto, Heungjin Ryu et al.•ARTICLE•Primates•2022

    The operational sex ratio (OSR) is used as a predictor for the intensity of mating competition. While many factors affect the OSR, there tends to be a high male bias in primate species with long interbirth intervals and non-seasonal breeding, such as hominid apes. However, the OSR of bonobos ( Pan paniscus ) is lower than that of chimpanzees ( Pan troglodytes ), which is thought to reduce competitive and aggressive male behaviors. The low OSR of …
