“…The impacts of habiat fragmentation and loss on magnitude genetic diversity and its patterns have been investigated in different Salix species. The implications of the results have been discussed with respect to conservation and restoration of natural populations in these studies (Kikuchi et Değirmenci et al 2022). Even though, natural habitats of the species in its natural range have been degraded dramatically in Türkiye, there is no study to date, dealing with the genetic structure of goat willow populations in these highly disturbed habitats.…”

Goat willow (Salix caprea L.) is an ecologically important, cold-tolerant pioneer species that spread from central Anatolia to the Black Sea regions in Türkiye. Completed and ongoing construction of hydroelectric plants, especially in northeastern Turkey, threaten the genetic resources of goat willow in the region due to habitat loss and fragmentation. Therefore, it is important to asses genetic diversity structure and magnitude of goat willow populations in the northeastern Black Sea Region for effective conservation of genetic resources of the species. To characterize the genetic diversity of Salix caprea, 180 trees were sampled and screened by using ten microsatellite markers for genotyping, consequently analysis were carried out to estimate population genetic diversity parameters of populations. The results revealed that both observed (Ho = 0.50) and expected (He = 0.54) genetic diversities were low, but observed genetic diversity was less than expected due fragmentation and reduction in population sizes. Genetic structure analysis of populations suggested the presence of two major groups. One included the populations of Trabzon provinces and the other had the populations of the Artvin provinces. This structuring appeared to be caused by the restricted gene ow (polen, seed or vegetative material) through wind and water) due to geographical barrier (the east Black Sea mountain ranges) acting as geographic isolation mechanism between the populations of Trabzon and Artvin provinces. To prevent further deteroiation of genetic diversity due to habitat loss and fragmentation in the studied river systems in the region, it is suggested that effective gene conservation and management programs should be developed for the species by using the genetic information from the current study.

Integrative phylogeographic studies supported by morphometric analysis and genetic data provide significant insights into the postglacial recolonization history and other factors shaping current distributions of plant species, including major forest-forming trees in Europe. However, genomic resources and phylogeographic knowledge of shrub species remain limited. Staphylea pinnata L. (European bladdernut) is a shrub native to thermophilous broadleaf forests and is the only representative of the Staphyleaceae in Central Europe. Given its historical associations with human and religious beliefs dating back to pre-Christian cultures, the current distribution of this iconic, Neogene relic species has been hypothesized to be influenced by human-assisted migration. This study aims to address this hypothesis by uncovering the genetic and morphometric relationships among S. pinnata populations across its wide distribution range in Europe, Caucasus and the Anatolian Peninsula, linking these findings with existing archaeobotanical and ethnobotanical data. We sampled 87 populations (979 individuals), genotyped them with the applications of newly developed genetic markers, and conducted morphological leafs’ measurements to estimate the postglacial expansion and human impact on the current distribution of S. pinnata. Both genetic and morphometric results indicate primarily natural post-glacial recolonization from two Pleistocene glacial refugia in the Apennines and Balkans. Additionally, we identified “suture zones” of increased genetic diversity in middle latitudes, resulting from secondary contact due to postglacial recolonization from different sources. Significant human contributions were observed towards the northernmost edge of the species’ range, including regions such as Eastern France, Lower Silesia in Poland, and Northern Podolia in Ukraine.
