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

为了探讨日本琉球中部黑河龙种的遗传多样性和保护，我们分析了线粒体DNA序列约1,200个碱基的变异。结果不支持形态基础上假设的关系，因为目前的结果强烈地表明，来自Amami岛群的G.K.Splendens和冲绳岛群的其余亚种之间的初级二分性具有实质性的遗传分化，并且在冲绳岛群的其余亚种中至少存在六个独立的谱系，表明G.K.kuroiwae和G.K.Orientalis的每个亚种都是非单系的。从保护遗传学的观点来看，所有的种群都濒临灭绝。

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.
