Phylogenetic relationships among 18 species of mainly European muroid rodents that belong to three subfamilies were estimated using complete sequences of the mitochondrial cytochrome b gene. The inferred monophyly of the subfamilies Murinae (mice and rats) and Arvicolinae (voles, lemmings, and muskrats) is in agreement with previous studies. Within the Murinae, the morphology-based division of the genus Apodemus into three subgenera is supported by these DNA sequence data. The relationships among the different genera of the Murinae were generally poorly resolved, and the relationships of Micromys and Acomys to the other murine genera remained unresolved. Within the subfamily Arvicolinae, the relations of the genera Arvicola, Clethrionomys, and Microtus remained tentative with our data. However, within the Microtus group, there is a good molecular support for the phylogenetic relationships. These findings suggest that the origin of the different murine and arvicoline lineages was rapid, indicating an adaptive radiation with fast speciation.
利用线粒体细胞色素b基因的完整序列,估计了主要属于三个亚科的18种欧洲鼠形啮齿动物之间的系统发育关系。推断出的鼠亚科(小鼠和大鼠)和田鼠亚科(田鼠、旅鼠和麝鼠)的单系性与先前的研究一致。在鼠亚科中,基于形态学将姬鼠属分为三个亚属的分类得到了这些DNA序列数据的支持。鼠亚科不同属之间的关系通常解析得很差,而巢鼠属和梳趾鼠属与其他鼠属的关系仍未解决。在田鼠亚科内,根据我们的数据,水䶄属、棕背䶄属和田鼠属之间的关系仍不确定。然而,在田鼠类群中,系统发育关系有很好的分子支持。这些发现表明,不同鼠类和田鼠类谱系的起源很快,表明是一个物种快速形成的适应性辐射过程。
