UNLABELLED • PREMISE OF THE STUDY The Caucasus represents one of the world's biodiversity hotspots and includes the climatic refugia Hyrcan on the southern coast of the Caspian Sea and Colchis on the eastern coast of the Black Sea, where different species survived during the Quaternary climatic oscillations. We evaluated the genetic diversity of the relict tree Zelkova carpinifolia shared bet...

Five species of clitocyboid fungi belonging to genus Clitocybe viz. ‍C. geotropa, C. houghtonii, ‍C. infundibuliformis,C. rufuloalutacea and C. trulliformisare reported from Iranian part of Caucasia. The reported fungi are new records for Iran.

the Quaternary climatic oscillations and persist today in isolated refugial areas is crucial for maintaining the global diversity of plants, especially considering the current climate trend of increasing temperatures and water stress ( Petit et al., 2005 ; Kozlowski et al., 2012 ). The Arcto-Tertiary relict fl ora, that covered large parts of the northern hemisphere during the Eocene but since ...

Analysis of genetic structure and differentiation using 12 microsatellite loci of six walnut populations, three each from the Greater Caucasus and the Talysh, revealed a moderate range of variation. The observed number of alleles ranged from 2 to 11 alleles with a mean of 5.6 alleles per locus. The populations differed significantly for the frequency and composition of alleles for ten out of tw...
