The success and viability of an ex-situ conservation program lie in the establishment and potential maintenance of a demographically and genetically viable insurance population. Such population reserve may support reintroduction and reinforcement activities of wild populations. White-naped mangabeys are endangered restricted-range African primates which have experienced a dramatic population decrease in their natural habitats over the last few decades. Since 2001, some European zoos singularly monitor an ex-situ population aiming to seek the recovery of the current wild population. The aim of the present paper is to evaluate the genetic status and population demographics of European zoo-captive white-naped mangabeys based on pedigree data. The captive population is gradually growing and preserves specific reproductive and demographic parameters linked to the species. The intensive management program that is implemented has brought about the minimization of inbreeding and average relatedness levels, thus maintaining high levels of genetic diversity despite the existence of fragmented populations. This finding suggests white-naped mangabey ex-situ preservation actions may be a good example of multifaceted conservation throughout studbook management which could be used as a model for other ex-situ live-animal populations.
迁地保护项目的成功和可行性取决于建立和维持具有人口统计学和遗传可行性的保险种群。这样的种群储备可以支持野生物种的重新引入和强化活动。白颈长尾猴是濒危的非洲限定范围的灵长类动物，在过去几十年中，它们在自然栖息地的数量急剧减少。自 2001 年以来，一些欧洲动物园单独监测一个迁地种群，旨在寻求当前野生种群的恢复。本文的目的是评估基于系谱数据的欧洲动物园圈养白颈长尾猴的遗传状况和种群人口统计学。圈养种群正在逐渐增长，并保留了与该物种相关的特定繁殖和人口统计学参数。实施的密集管理计划已经最大限度地减少了近亲繁殖和平均亲缘关系水平，从而维持了高水平的遗传多样性，尽管存在种群碎片化的情况。这一发现表明，白颈长尾猴的迁地保护行动可能是一个很好的例子，说明了通过族谱管理进行多方面的保护，可以作为其他迁地活体动物种群的模型。
