摘　　要：Although seasonal breeding has been documented in many non-human primates, it is not clear whether sexual behaviors show seasonal variation among male individuals. To test this hypothesis, the focal animal sampling method and continuous recording were used to investigate seasonal variation and synchronization of sexual behaviors in five male Tibetan macaques （Macaca thibetana） at Mt. Huangshan from Oct 2005 to Sept 2006. Both copulatory and sexually motivated behaviors （i.e., sexual chase, grimace, and sexual-inspection）, which were significantly higher in the mating season than non-mating season. Furthermore, seasonal variations of sexual behaviors, including copulatory and sexually motivated behaviors, were synchronized among males. The results shed light on sexual competition and tactics for reproductive success of male M. thibetana and other non-human primates with seasonal breeding.季节性繁殖是非人灵长类动物的普遍特征,而野生雄性个体的性行为季节性变化特点仍有待研究。该研究于2005年10月至2006年9月对黄山短尾猴鱼鳞坑YA2群5只成年雄性个体进行全年观察,以期探讨雄性黄山短尾猴性行为季节性变化特征。结果表明:繁殖季节交配行为和性动机行为(性追赶,做鬼脸和性检查)频次显著高于非繁殖季节,季节性差异显著。成年雄性个体交配行为和性动机行为季节性变化呈现显著同步性。该研究为进一步阐明短尾猴和同属季节性繁殖非人灵长类动物的雄性竞争和雄性策略提供理论依据。
