Chromosomal mechanisms underlying the karyotype evolution of the oriental voles (Muridae, Eothenomys)

We have investigated the karyotype relationships of two oriental voles, i.e. the Yulong vole (Eothenomys proditor, 2n = 32) and the large oriental vole (Eothenomys miletus, 2n = 56) as well as the Clarke's vole (Microtus clarkei, 2n = 52), by a combined a

Molecular phylogeny and biogeography of Oriental voles: genus Eothenomys (Muridae, Mammalia)

Oriental voles of the genus Eothenomys are predominantly distributed along the Southeastern shoulder of the Qinghai-Tibetan Plateau. Based on phylogenetic analyses of the mitochondrial cytochrome b gene (1143 bp) obtained from 23 specimens (eight species)

The boundary of palaearctic and oriental realms in western China

In the world-wide zoogeographic division, there has been no consentaneous understanding about the delimitation between palaearctic and oriental realms in western China. In this study, we will discuss the division based on amphibian distribution in Shaanxi, Gansu, Sichuan, Yunnan, and Tibet according to species coefficient similarity between each zoogeographic province. The results show that the northern border lies from Qinling Mountains-Feng Xian (Shaanxi)-Debu (Gansu)-Aba (Sichuan)-Batang-Bomi (Tibet), to Linzhi districts, and the southern border is from Taibai-Feng Xian in Shaanxi-Wen Xian (Gansu)-Songpan-Kangding-Daocheng (Sichuan), to Zhongdian-Gongshan in Yunnan, and westward to Motuo and Bomi district in Tibet.
