摘要

We conducted a phylogeographic study of two Mustela species, the European polecat (M. putorius) and steppe polecat (M. eversmanii), across a large area of their ranges based on partial sequences of the mitochondrial control-region. Our study identified 47 haplotypes from 81 M. eversmanii and 22 M. putorius individuals; combining our data with previous data, we analysed 75 known haplotypes from 169 polecats: 86 M. eversmanii, 65 M. putorius and 18 domesticated ferrets (M. p. furo). Both a maximum-likelihood tree and median-joining network revealed two major clades (I and II); Clade I comprised entirely M. eversmanii individuals, mostly from East Asian populations, with one exception, whereas Clade II comprised individuals from across the range from East Asia to West Europe. Haplotypes from M. eversmanii were separated between the two clades, suggesting genetic differentiation between the eastern and western parts of continental Eurasia. Clade II contained a mixture of haplotypes from M. eversmanii, M. putorius and M. p. furo. Gene flow between M. eversmanii and M. putorius around eastern Europe is consistent with previous hybridization reported between these species. Our results indicate that M. putorius furo was domesticated from M. putorius, although additional information is needed to confirm this.
