9520947 Densmore This research involves collection of samples of a rhacophorid frog fauna from five hypothesized areas of endemism which comprise the Japan Archipelago and Taiwan, and phylogenetically related or geographically proximate taxa from the Asian continent. From these specimens, two independent data sets derived from mtDNA and morphology will be analyzed independently and in concert to construct phylogenetic hypotheses for two distinct lineages which have representatives inhabiting these areas of endemism. The resulting phylogenies will be used to test whether the present distribution patterns of these frogs are the result of past vicariant events and to present a hypothesis of their historical biogeography. This hypothesis will then be analyzed along with the known geology of the archipelago to yield a general biogeographic hypothesis for the Japan Archipelago, which can be used to evaluate distributional patterns of other fauna and flora in Japan and Asia.

9520947登斯摩尔这项研究涉及从日本群岛和台湾等五个假设特有区收集犀蛙类动物样本，以及来自亚洲大陆的在系统发育上或地理上相近的类群。从这些标本中，来自线粒体DNA和形态的两个独立的数据集将被独立和一致地分析，以构建两个不同谱系的系统发育假说，这两个谱系的代表居住在这些特有的区域。由此产生的系统发育将被用来测试这些青蛙目前的分布模式是否是过去替代事件的结果，并提出它们历史生物地理的假说。这一假说将与该群岛的已知地质情况一起分析，得出日本群岛的一般生物地理假说，该假说可用于评估日本和亚洲其他动植物的分布格局。
