Genetic diversity of represents the evolutionary history of species and the essential evolutionary potential to respond to changing environments especially for endangered species. Microsatellites are currently the most practical and informative molecular maker for measuring genetic variation within populations. In this study, we developed microsatellite markers for nine endangered amphibian species endemic to Ryukyu Islands in Japan. By using these markers, fine scale population structures and genetic diversities of these species were revealed. These results have contributed to effective conservation and enabled genetic management of ex-situ conservation activities of these endangered amphibians.

遗传多样性代表了物种的进化史和应对环境变化的基本进化潜力，尤其是濒危物种。微卫星是目前测量种群内遗传变异最实用和信息最丰富的分子制造工具。本研究对日本琉球群岛特有的9种濒危两栖动物进行了微卫星标记。利用这些标记，揭示了这些物种的精细群体结构和遗传多样性。这些结果有助于有效地保护这些濒危两栖动物，并为移地保护活动提供遗传管理。
