物种内生物多样性的丧失可能会显着降低面对环境变化的恢复能力。遗传变异的保护需要考虑物种内所有可用的多样性来源,并且需要采取一些方法来整合传统上分离的野生和圈养种群领域的种群管理。在这里,我们报告了一项研究,该研究利用不同分类尺度和跨原地-易地转变的不同类型的遗传分析来支持日本金雕的保护规划,日本金雕是一个区域性严重衰退的亚种。线粒体 DNA 测序和核 DNA 分析用于研究自然种群中的亚种分化和多样性,揭示了日本相对较高水平的变异。将这些结果与新建立的保护育种计划的数据进行比较,该计划表明圈养创始人的野生遗传变异具有良好的代表性。然而,随后对圈养种群的人口统计和遗传未来进行的种群生存力分析(PVA)表明,现有生殖偏差的严重影响,表明如果没有强化的遗传管理,该种群就无法可持续发展。最后,在圈养和野生保护管理的背景下,评估和讨论了使用现有的分子工具来验证和重建日本金雕的谱系。本文强调了在整个种群管理范围内生成和利用比较分子遗传数据的重要性以及 PVA 支持实施综合保护计划的好处。
The loss of biological diversity within species has the potential to significantly reduce resilience in the face of environmental change. Conservation of genetic variation needs to consider all available sources of diversity within a species, and approaches are required to integrate population management across traditionally separate wild and captive population domains. Here we report on a study that utilises different types of genetic analysis at different taxonomic scales and across anin situ – ex situtransition to support conservation planning for the Japanese golden eagle, a subspecies in serious regional decline. Mitochondrial DNA sequencing and nuclear DNA profiling are used to investigate subspecies differentiation and diversity in the natural population, revealing relatively high levels of variation in Japan. These results are compared with data from a newly established conservation breeding programme that indicates good representation of wild genetic variation in the captive founders. However, subsequent population viability analysis (PVA) to examine the demographic and genetic future of the captive population demonstrates the severe effects of existing reproductive skews, suggesting that this population is not sustainable without intensive genetic management. Lastly, the use of available molecular tools to validate and reconstruct pedigrees in Japanese golden eagle are evaluated and discussed in the context of captive and wild conservation management. The paper highlights the importance of producing and utilising comparative molecular genetic data across the population management spectrum and the benefits of PVA to support the implementation of integrated conservation plans.
