Description
Summary:The phylogenogeographic structure, polymorphism, and differentiation of Pinus sylvestris L. have been studied for the first time by means of allozyme analysis of 143 populations along a network of transects covering the entire species range. The results show that the species in general is characterized by a significant level of differentiation, regardless of its relative uniformity in northern and central parts of the range. Nei’s genetic distances between populations and their gradients in the extreme southern parts of the range, where it has an insular pattern, are seven to eight times greater than in the northern, “glacial” zone. Three Pleistocene refugia for the species have been revealed in the Balkans, Southern Urals, and Northern Mongolia. Using analysis of genetic distances between 18 phylogeographic regions and an original genosystematic scale, one subspecies, five geographic races and nine geographic population groups have been distinguished in the P. sylvestris L. species structure.
