Description
Summary:The genetic variety of seven geographic populations of sable has been studied; its distribution area stretches from the Urals to the Far East. It was shown using the panel of eight nuclear microsatellite markers that the sable populations from different geographical regions retain their individual genetic characteristics, despite the influence of anthropogenous factors (overhunting and introduction). There is a significant genetic similarity between the three populations of Central Siberia (Reynolds distances are 0.170–0.200) due to the influence of natural migrations that weaken genetic differentiation, while genetic difference is maximum (0.361) between populations located at the edges of the sable’ habitat. The population of the Kamchatka Peninsula is isolated and exists as an independent phylogenetic group. An analysis of the topology of the phylogenetic tree suggests that the populations of Kamchatka and the Sikhote-Alin are closest to the ancestral form. Despite the existence of interspecific hybrids of sable and marten, the level of interspecific genetic differentiation between them is maximal.
