Abstract Development of agriculture in the forest and forest-steppe zones of the vast East European plain over the past millennium has resulted to a significant decrease of broad-leaved forests habitat. It is expected that the disintegration of the forest tree species distribution ranges will lead to the erosion of the population genetic diversity of due to limited gene flow, impacts on gene pools of genetic drift and inbreeding. To investigate this threat, we analyzed the genetic diversity and differentiation among 20 populations of pedunculate oak (Quercus robur L.) from the Ural Mountains (Russia) and neighboring lowlands and foothills. A set of 412 nuclear SNPs loci was used for our study. A positive correlation (r = 0.168, p
