摘　　要：主雄替换是金丝猴繁殖权更迭中重要的一环,是金丝猴个体繁殖策略的关键,对种群繁衍生息具有着重要意义。陕西周至国家级自然保护区玉皇庙秦岭川金丝猴种群中,交配权的更迭主要发生在每年10—12月的繁殖期。研究者观察了两起主雄替换事件,并完整观察到其中发生于2023年10月25—30日的主雄替换过程。观察结果表明,在主雄替代过程中原主雄与家庭内雌性的理毛和交配频率明显降低;替换后新主雄与家庭内雌性理毛和交配频率逐步增加,但该家庭在繁殖群内的等级明显下降。The resident male takeover is an important part of the succession of reproductive rights,and is a key strategy for individual reproduction in snub-nosed golden monkeys,playing a great role in the population reproduction and survival.The takeover of mating rights of the Qinling snub-nosed monkey bands in Yuhuangmiao,Zhouzhi National Nature Reserve,Shaanxi,mainly occur during the breeding season from October to December each year.The researchers observed two events of resident male takeovers,one of which occurred from October 25-30,2023 and documented.During the process of resident male takeover,the allogrooming and mating frequency between the former resident male and female members of the band significantly decreased.After takeover,the frequency of allogrooming and mating between the new resident male and female members of the band gradually increased,showing a significantly decreased social rank.
