Genetic structure and postglacial recolonization of <i>Pinus sibirica</i> Du Tour in the West Siberian Plain, inferred from nuclear microsatellite markers

Abstract The total of 257 trees from the ten natural Siberian stone pine populations West Plain, Ural Mountains and Kuznetsk Alatau were studied with eight nuclear microsatellite loci. Differentiation population groups indicates possible existence separate refugia in past Urals Alatau. northern Western Siberia characterized by a reduced level genetic diversity, which could be consequence founder effect process P. sibirica migration southern regions since end last glacial maximum. variability distribution among shows uneven dynamics zones supposed refugia. map proposed ways was constructed, it is good agreement results palynological investigations.
