两栖动物在全球范围内正在减少，全面了解遗传多样性的空间分布将为保护工作提供信息。然而，估计两栖动物种群遗传结构和基因流的研究尚未综合起来。我们从2001年到2010年的文献搜索产生了552项两栖动物种群和景观遗传研究，其中139项明确估计了基因流或遗传结构。我们检查了这些工作的一般趋势，并对报告的F-ST值进行了荟萃分析。大多数研究是在北美和欧洲的温带森林进行的，没有对尾虫的研究，也很少对直接发育的物种进行研究。在景观遗传学研究中，河流、道路和山脊是确定的主要障碍。保护状态是唯一显示与F-ST有显著关系的因素，最不受关注的IUCN状态与接近威胁(NT)状态以及包括NT的IUCN状态的任何组合显著不同。最近的技术进步将帮助研究人员填补分类学和地理研究的空白，从而促进解决两栖动物物种更大多样性的管理计划。
Amphibians are declining globally, and a comprehensive understanding of the spatial distribution of genetic diversity will inform conservation efforts. However, studies that estimate amphibian population genetic structure and gene flow have not yet been synthesized. Our search of literature from 2001 to 2010 yielded 552 amphibian population and landscape genetic studies, of which 139 explicitly estimated gene flow or genetic structure. We examined these works for general trends and conducted a meta-analysis of reported F-ST values. The majority of studies took place in temperate forests in North America and Europe, with no studies of caecilians and few studies of direct-developing species. Among landscape genetic studies, rivers, roads, and mountain ridges were the predominant barriers identified. Conservation status was the only factor that showed a significant relationship with F-ST, with the least concern IUCN status differing significantly from the near threatened (NT) status as well as from any combination of IUCN statuses that included NT. Recent technological advances will help researchers fill taxonomic and geographic research gaps, thereby facilitating management plans that address a greater diversity of amphibian species.
