摘要

摘要对新发现于日本北海道东部Kamishihoro-cho的14个西伯利亚蝾螈(Salamandrella keyserlingii)种群的线粒体细胞色素b基因进行了测序，并进行了系统发育分析，以揭示该种群的遗传同源性。Kamishihoro种群与地理上相邻的北海道Kushiro种群关系最密切，但具有单一独特的单倍型。这一结果表明，神石堀种群不是引种种群，而是本地种群。keyserlingii Salamandrella keyserlingii被认为曾经广泛分布于萨哈林岛至北海道，但后来北海道的范围大大缩小，在中更新世0.34 MYBP时，Kamishihoro和Kushiro种群出现了分化。

A Genetic Study of a Newly Found Population of Siberian Salamander, Salamandrella keyserlingii (Amphibia, Caudata)

Abstract: We sequenced mitochondrial cytochrome b gene of 14 samples of Siberian salamander, Salamandrella keyserlingii, from a population newly found in Kamishihoro-cho, eastern Hokkaido, Japan, and conducted phylogenetic analysis to reveal genetic identity of the population. The Kamishihoro population was most closely related to the geographically adjacent Kushiro population from Hokkaido, but possessed a single, unique haplotype. This result indicates that the Kamishihoro population is not an introduced, but a native population. Salamandrella keyserlingii is thought to have been once widespread throughout Sakhalin to Hokkaido, but the range was greatly narrowed subsequently in Hokkaido, with the divergence of the Kamishihoro and Kushiro populations at 0.34 MYBP, Middle Pleistocene.
