Background Salix alba is a pioneer species of river ecosystems throughout Turkey. Its genetic diversity and population structure across these ecosystems is currently unknown. Aims We investigated genetic diversity in Turkish S. alba to assess factors likely to shape the genetic structure of the species and to assist with conservation recommendations. Methods Six hundred and forty-six individuals from 10 major river systems in Turkey were genotyped using 15 microsatellite markers. Between one and five sub-populations were sampled from each river system with 23 sub-populations sampled in total. Results Populations contained moderately high levels of genetic diversity. Five genetic groups were detected by Bayesian clustering, with samples from particular river systems mainly assigned to particular genetic groups. This revealed a geographic structure, also detected by principal coordinate analysis, showing that particular river system populations in different parts of Turkey were genetically similar to each other but different from those in other parts of the country. Conclusion Genetic isolation caused by geographic distance (in part) and natural barriers among river systems appear to have shaped the genetic structure of populations. The results have important implications for the conservation of genetic resources within S. alba and restoration of degraded Turkish populations of the species.

Genetic diversity pattern in Populus Nigra populations of two major river systems in Turkey Çiftçi, Asiy; Kaya, Zeki; Department of Biology (2019) European black poplar (Populus nigra L.) is an important tree species in terms of social, economic and ecological interest in Turkey. Although, poplar plantations in large areas meet the needs of the economy, the natural genetic resources of the species have been highly degraded due to anthropogenic effects and natural biological events. To assess genetic diversity structure of natural populations, 124 naturally distributed European black poplar trees from two major rivers (Kızılırmak and Göksu) in Turkey w...
Genetic differentiation between clone collections and natural populations of European black poplar (Populus nigra L.) in turkey Çiftçi, Asiye; Kucukosmanoglu, Filiz; Karahan, Alptekin; Kaya, Zeki (2017-06-01) The European black poplar (Populus nigra L.) is an ecologically and economically important tree species for Turkey. The important and major genetic resources of species for future breeding and ex situ conservation purposes have been archived in a clone bank in Ankara by selecting clones from natural populations and old plantations throughout Turkey. There is no study to date assessing genetic composition these materials. Two-hundred-thirty-three P. nigra clones from six geographic region of Turkey (clone co...
DIFFERENTIAL IMPACTS OF HABITAT FRAGMENTATION ON GENETIC STRUCTURE OF TWO IMPORTANT RIPARIAN SPECIES (SALIX ALBA & POPULUS NIGRA) Durgut, Bilge; Kaya, Zeki; Department of Molecular Biology and Genetics (2022-2-23) Salix alba and Populus nigra are two important tree species of riparian ecosystems. With a great ecologic and economic significance, they are naturally distributed in almost all river basins of Turkey. The genetic structures of these species in two river basins in Turkey were studied using eight common microsatellite markers to both species to reveal the impacts of habitat fragmentation. Therefore, the studied rivers were selected to represent a highly fragmented river, and a protected river from habitat fr...
Genetic variation in Turkish red pine (Pinus brutia Ten.) seed stands as determined by RAPD markers Kandedmir, GE; Kandemir, I; Kaya, Zeki (2004-01-01) Turkish red pine (Pinus brutia Ten.) is one of the important tree species in Turkey. The species has been heavily disturbed by anthropogenic factors and fire, making it important to understand the magnitude of the impact on genetic diversity of areas reserved for seed production. To explore the extent of genetic variation in Turkish red pine seed stands, a random amplified polymorphic DNA (RAPD) marker system was used in the study. The estimated genic diversity for seed stands was found to range from H=0.17...
Genetic Diversity Pattern of Salix alba Populations in a Fragmented River Ecosystem in Eastern Mediterranean Özdemir Değirmenci, Funda; Acar, Pelin; Kaya, Zeki (null; 2016-01-13) The genus Salix L. is represented with more than 500 species in the world and 28 of species are found naturally in Turkey. The species of the genus have been widely used for bioenergy and phytoremediation. Salix alba like many other willow species is with great renewable energy potentiali and important component of an healthy riparian ecosystem as an indicator species in major river ecosystems in Turkey. With this study, it was aimed to provide information for efficient conservation, management and util...
