Abstract

The genetic and phenotypic structure (according to the fur color) of 14 sable samples from the Baikal mountain land (BML) has been studied by analyzing 257 animals for 11 microsatellite loci and evaluating over 12 000 pelts with respect to seven standard color categories. It has been found that the population structure of sable in the region is heterogeneous both phenotypically and genetically. An isolated population group of sable with dark fur inhabits Zabaikalsky krai (Uletovsky, Petrovsk-Zabaikalsky, and Krasnochikoysky districts). The Khamar-Daban Ridge in the south of Lake Baikal is inhabited by a sable population with a high genetic diversity and the lightest fur color in the study region, which is most likely due to its contacts with the East Sayan population. The other BML samples have a relatively high genetic diversity and intermediate parameters of fur color, which may result from their large-scale intraregional translocations and migrations. The results of comparative tests suggest an indirect correlation between the phenotypic and genetic structures in samples from at least seven sable populations inhabiting the study region.

贝加尔湖山地黑貂的种群结构：遗传和表型性状分析

摘要

通过对257只动物的11个微卫星基因座进行分析并针对7种标准颜色类别评估了超过12 000个兽皮，对贝加尔湖山地（BML）的14个黑貂样品的遗传和表型结构（根据毛皮颜色）进行了研究。已经发现该区域中黑貂的种群结构在表型和遗传上都是异质的。孤立的黑貂黑貂种群居住在扎拜卡尔斯基（Uletovsky，Petrovsk-Zabaikalsky和Krasnochikoysky区）。贝加尔湖南部的Khamar-Daban山脊栖息着一个稳定的种群，该种群具有较高的遗传多样性，并且在研究区域内的毛皮颜色最浅，这很可能是由于它与东萨彦岭种群有联系。其他BML样品具有相对较高的遗传多样性和皮毛颜色的中间参数，这可能是由于它们的大规模区域内易位和迁移所致。比较测试的结果表明，来自研究区域的至少七个黑貂种群的样本的表型和遗传结构之间存在间接关联。
