- Аннотация: Quaternary climatic luctuations changed the loristic composition of large areas and forced biota to repeated movements following gradients of their ecological tolerance. Diferent and contrasting patterns of responses were reported for various species. In this study we focused on Adenophora liliifolia, a perennial herbaceous species representing a south Siberian floristic element in European lora, well adapted to a continental climate. We investigated the genetic diversity and phylogeography of the species within Europe. The results show the absence of stronger sequence diferentiation across the investigated 3600 km long transect, which relects the young evolutionary origin of the species and/or repeated population contractions/expansions accompanied by bottleneck during the Quaternary climatic luctuations. Along with this, the results suggest several regions located in Carpathians, Alps-Dinarides, and in non-glaciated parts of Central Russia with high haplotype diversity, which probably served as refugia. Low genetic diversity, the prevalence of a single cpDNA haplotype, and the genetic composition of the investigated European sites suggest re-colonization of Central Europe from a refugium located in southern Europe. The distribution of genetic variation and moderate genetic diferentiation of the investigated sites may indicate the process offragmentation of the common genetic pool in Central Europe. Projections of ongoing climate change during the twenty-first century are not favorable for species persistence in Central Europe. In the case of ex-situ conservation actions, we recommend protection and proper management of rapidly vanishing populations and maintenance of genetic diversity, especially in regions with high haplotype diversity.
