Abstract：
Release of individuals is an effective conservation approach to protect endangered species. To save this small isolated giant panda population in Liziping Nature Reserve, a few giant pandas have been released to this population. Here we assess genetic diversity and future changes in the population using noninvasive genetic sampling after releasing giant pandas. In this study, a total of 28 giant pandas (including 4 released individuals) were identified in the Liziping, China. Compared with other giant panda populations, this population has medium-level genetic diversity; however, a Bayesian-coalescent method clearly detected, quantified, and dated a recent decrease in population size. The predictions for genetic diversity and survival of the population in the next 100 years indicate that this population has a high risk of extinction. We show that released giant pandas can preserve genetic diversity and improve the probability of survival in this small isolated giant panda population. To promote the recovery of this population, we suggest that panda release should be continued and this population will need to release 10 males and 20 females in the future.
摘要：
释放个体是保护濒危物种的有效保护方法。为了拯救丽子坪自然保护区的这只孤立的小型大熊猫种群，一些大熊猫已经被释放到这个群体中。在这里，我们使用释放大熊猫后的非侵入性遗传采样来评估种群的遗传多样性和未来变化。在这项研究中,在黎子坪共鉴定出28只大熊猫(包括4只放生个体),中国。与其他大熊猫种群相比，该种群具有中等水平的遗传多样性；然而，一种清晰检测到的贝叶斯聚结方法，量化,并注明了最近人口规模的减少。对未来100年种群遗传多样性和生存的预测表明，该种群灭绝的风险很高。我们表明，放生的大熊猫可以保留遗传多样性，并提高这种小型孤立大熊猫种群的生存概率。为了促进这一人口的恢复，我们建议继续释放熊猫，这个种群将来需要释放10只雄性和20只雌性。
