项目摘要

Just as planned in the proposal, sampling of fresh specimens of Takydromu tachydromoides was carried out in some islands of the Tokara and Osumi Island Groups, as well as in some localities of southern Kyushu, from which only a few specimens had been available yet. Then, sampling efforts were extended to other localities in the remaining region of Kyushu (Nagasaki and Oita) and adjacent islands (e.g., Goto Islands and Iki), as well as in Western Honshu (Kyoto), Central Honshu (Mie and Gifu), Vicinity of Tokyo (Ibaragi, North-central Honshu (Ishikawa), North-eastern Honshu (Sendai), and Hokkaido (Sapporo). Special efforts were made to obtain fresh materials from both high and low altitude areas of Yakushima Island, because some previous authors noted that the populations from these regions might be morphologically distinct from each other. Tissues were obtained from these materials and were subjected to molecular phylogenetic analyses. The remaining parts were preserved and subjected to … More morphological analyses together with other specimens loaned from museums and other researchers.Morphologically, prominent variations were recognized between samples from the Tokara Island Group and Kyushu+Honshu+Hokkaido samples, but these two assemblages were more or less bridged by the Osumi Island samples. Analyses of sequence variations in mitochondrial 12S and 16S rRNA genes yielded trees that indicate prominent dichotomy between the Tokara+Osumi populations and whole of the remainder. This result, along with available paleogeographical and paleoclimatic information, strongly suggests that populations from these two areas actually represent different biological species. On the other hand, altitudinal divergence on Yakushima Island was not supported at all. Very little variation was recognized among all samples from Gifu and more northern localities. This suggests that populations from the northern half of Japan represent rapid post glacier dispersals during the Late Pleistocene-Holocene period. Less
正如提案中所计划的那样,在Tokara和Osumi岛群的一些岛屿以及九州南部的一些地方对Takydromu tachydromoides的新鲜标本进行了取样,这些地方目前只有少数标本。然后,将采样工作扩展到九州其余地区(长崎和大分)和邻近岛屿的其他地方(例如,后藤群岛和伊基),以及本州西部(京都)、本州中部(三重和岐阜)、东京附近(茨城、本州中北部(石川)、本州东北部(仙台)和北海道(札幌)。特别努力从屋久岛的高海拔和低海拔地区获得新鲜材料,因为一些以前的作者指出,这些地区的人口可能在形态上彼此不同。从这些材料中获得组织,并进行分子系统发育分析。剩下的部分被保存下来, ...更多信息 从形态学上看,Tokara岛群和九州+本州+北海道的样品之间存在显著的差异,但这两个组合或多或少被Osumi岛样品所桥接。线粒体12 S和16 S rRNA基因的序列变异分析产生的树,表明显着的二分法之间的Tokara+Osumi人口和整个其余的。这一结果,沿着与现有的古地理和古气候信息,强烈表明,人口从这两个地区实际上代表不同的生物物种。另一方面,屋久岛的海拔差异根本没有得到支持。从岐阜和更多的北方地区的所有样品中发现的变异很小。这表明,人口从日本北方一半的冰川后迅速扩散在晚更新世-全新世时期。少
