Abstract Human-induced changes to environments are causing species declines. Beyond preserving habitat (in situ), insurance (ex situ) populations are essential to prevent species extinctions. The Conservation Centers for Species Survival (C2S2) is leveraging space of breeding centers and private ranches to produce “source populations”—genetically diverse reservoirs that also support research and reintroductions. The initial focus is on four African antelopes. C2S2 has developed a program, the Source Population Alliance, that emphasizes animals living in spacious, naturalistic conditions in greater numbers than can be accommodated by urban zoos. Simulation modeling demonstrates how herds can rapidly increase population abundance and retain genetic diversity. Advances in genomics and resulting DNA data allow monitoring of genetic diversity and parentage as well as refined decision-making. This approach, neither pure in situ nor ex situ, but rather “sorta situ”, is an innovative way of linking public and private sector resources to ensure that endangered species survive.

培育可持续野生动物种群的育种中心、私人牧场和基因组学

摘要 人类引起的环境变化正在导致物种减少。除了保护栖息地（就地）外，保险（迁地）种群对于防止物种灭绝至关重要。物种生存保护中心 (C2S2) 正在利用育种中心和私人牧场的空间来生产“源种群”——遗传多样性的水库，也支持研究和重新引入。最初的重点是四只非洲羚羊。C2S2 开发了一个名为 Source Population Alliance 的计划，该计划强调生活在宽敞、自然条件下的动物数量超过城市动物园所能容纳的数量。模拟建模展示了畜群如何快速增加种群数量并保持遗传多样性。基因组学的进步和由此产生的 DNA 数据允许监测遗传多样性和亲子关系以及精确的决策。这种方法既不是纯原地也不是非原地，而是“原生地”，是一种将公共和私营部门资源联系起来以确保濒危物种生存的创新方式。
