Genetic diversity and conservation of Goniurosaurus kuroiwae from the Ryukyu Archipelago, Japan, with special reference to the relationshipsamong its populations

为了探讨日本中琉球地区黑波角龙的遗传多样性和保守性，我们分析了线粒体DNA序列约1200个碱基位置的变异。结果不支持形态学基础上的关系假设，因为目前的结果强烈表明，天美岛群的锦葵与冲绳岛群的其余亚种之间存在着主要的二元分化，并存在着大量的遗传差异，而冲绳岛群中至少存在6个独立的谱系，表明黑河锦葵和东方锦葵都是非单系的。从保护遗传学的观点来看，所有种群都处于濒危状态。

We analyzed variations in approximately 1,200 base positions of mitochondrial DNA sequences in order to discuss genetic diversity and conservation of Goniurosaurus kuroiwae from the Central Ryukyus, Japan. Results do not support the relationships hypothesized on the morphological ground in that the present results strongly suggest that the primary dichotomy, with substantial genetic divergence, between G. k. splendens from the Amami Island Group and the remaining subspecies from the Okinawa Island Group, and that the presence of at least six independent lineages within the latter, indicating non-monophyly for each of G. k. kuroiwae and G. k. orientalis. All populations are endangered from the viewpoint of conservation genetics.
