Abstract

To examine the taxonomic status of the Korean red-backed vole (Myodes regulus), the full cytochrome b sequences of 21 red-backed voles from Korea and northeast China were compared with the corresponding haplotypes from 12 species of Myodes and Eothenomys from GenBank. We identified five red-backed voles from Mount Changbai and Harbin as Myodes rufocanus and three from Harbin as M. rutilus, and we confirmed that the red-backed voles from Korea are M. regulus and not Eothenomys regulus. We found that M. regulus from Korea differed from the other five species of Myodes and that the interspecific distances between M. regulus and each of the two species from northeast China were 4.55% (M. rufocanus) and 11.1% (M. rutilus). We concluded that M. regulus is also genetically distinct and is an endemic species of Korea.

摘要

为了研究韩国红背鼠（Myodes regulus）的分类地位，我们比较了来自韩国和中国东北的 21 只红背鼠的完整细胞色素 b 序列与来自 GenBank 的 12 种 Myodes 和 Eothenomys 相应的单倍型。我们确定了来自长白山和哈尔滨的 5 只红背鼠为 Myodes rufocanus，3 只来自哈尔滨的红背鼠为 M. rutilus，并证实了来自韩国的红背鼠是 M. regulus，而不是 Eothenomys regulus。我们发现韩国的 M. regulus与其他 5 种 Myodes 物种不同，韩国的 M. regulus与来自中国东北的两个物种之间的种间距离分别为 4.55%（M. rufocanus）和 11.1%（M. rutilus）。我们得出结论，M. regulus 在遗传上也有明显的差异，是韩国特有的物种。
