The genetic structure of seven natural sable populations was investigated with the use of the original panel of 10 microsatellite loci. The populations were selected on the basis of the historical data on sable numbers fluctuations for the last 300 years, as well as on data on natural and artificial migrations affecting neighboring populations. We have demonstrated that the populations are in a state of genetic equilibrium for the majority of the loci. The genetic differences between three samples from Central Siberia populations were insignificant, and the fixation index values were relatively low. At the same time, populations from the margins of the species habitation areal were characterized by the highest fixation index values. We have shown for the first time that populations from different regions of the sable habitation areal maintain their specific features despite the influence of natural and artificial migrations. The current study, performed with nuclear genetic markers, made it possible to get insight into the genetic structure of the analyzed species as a whole.
