Consortship has been defined as a temporary association between an adult male and an estrous/receptive female. It has been considered as male mating strategies to improve male mating success and potential reproductive success. However, the female roles have been more or less neglected, and thus, less is known about female behavioral strategies during the consortship periods. In this study, during the two consecutive mating seasons, we collected behavioral data of free-ranging Tibetan macaques () habituated in Mt. Huangshan, China, to investigate female behaviors when she was consorted by an adult male. The results showed that (a) females were more likely to approach and exhibit sexual solicitation to their consorting males during the consorted period, and females also exhibited less approach to their nonconsorting males; (b) females exhibited strong responses (either departed distantly or formed affiliative relationships with their consorting male partner) when their consorting males mated with rival females or showed sexual motivation toward rival females; (c) female preferences were positively correlated to the duration of consortships and the frequencies of ejaculation copulations, independent of the social ranks of their consorting male partners. Our results suggested that female strategies played much more important roles in forming and maintaining consortship than previously assumed. It provides new insight into understanding female adaptive strategies to male strategies by forming consortships in multimale-multifemale primate species when males could not identify female's fertile phase accurately.
配偶关系被定义为成年雄性与处于发情期/接受期的雌性之间的临时关联。它被视为雄性提高交配成功率和潜在繁殖成功率的交配策略。然而,雌性的角色或多或少被忽视了,因此,对于配偶关系期间雌性的行为策略了解较少。在本研究中,在连续两个交配季节里,我们收集了在中国黄山习惯化的野生藏猕猴的行为数据,以调查雌性在与成年雄性形成配偶关系时的行为。结果表明:(a)在形成配偶关系期间,雌性更有可能接近与其形成配偶关系的雄性并表现出性求爱行为,并且雌性对非配偶关系的雄性的接近也更少;(b)当与其形成配偶关系的雄性与竞争雌性交配或对竞争雌性表现出性动机时,雌性会表现出强烈反应(要么远距离离开,要么与配偶关系的雄性伴侣形成亲密关系);(c)雌性的偏好与配偶关系的持续时间和射精交配的频率呈正相关,与配偶关系的雄性伴侣的社会等级无关。我们的结果表明,雌性策略在形成和维持配偶关系中所起的作用比之前认为的要重要得多。这为理解多雄多雌灵长类物种中,当雄性无法准确识别雌性的排卵期时,雌性通过形成配偶关系来应对雄性策略的适应性策略提供了新的见解。
