Searching for and Revealing Pleistocene Refugia of <Emphasis Type="Italic">Pinus sylvestris</Emphasis> L. in Central Yakutia

As a result of allozyme analysis, Nei’s genetic distances were determined between the phylogeographic group of seven populations of Pinus sylvestris L. in the “glacial” zone of the range in Central Yakutia and 25 populations of its hypothetical Pleistocene refugia of the southern nonglacial zone within the entire range of the species in Northern Eurasia. The location of the most likely “avant-garde” refugium of the modern yakutian populations of the Scots pine is Northern Priamur’e (Tynda), as well as less likely Siberian (Romanovka, Irkutsk), South Ural (Kryktytau), and Central European (the Czech Republic) refugia.
