Background and objectives: Plants belonging to the genus Tilia L. (Tiliaceae) are often tall beautiful trees which are considered for various medicinal potentials of their flowers and leaves. The present study was an attempt to investigate the phytochemical constituents of Tilia rubra subsp. caucasica leaves from the hyrcanian forests of north of Iran. Methods: Chromatography on Silica gel (nor...

Recent decades have witnessed the growing use of non-native plants in Iran while their use is very challenging and high-cost for the country. This raised a new approach in recent decades towards the use of native plants. Native species are precious because they possess the main ecological factors and they are already compatible with the region. Accordingly, this research was conducted to evalua...

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 ...

Abstract Pterocarya fraxinifolia , native to the southern Caucasus and adjacent areas, has been widely introduced in Europe. In this study, we investigate following: (1) How did its current distribution form? (2) What are past, current, future suitable habitats of P. ? (3) is best conservation approach? Ecological niche modeling was applied determine climatic demands project climatically areas ...

Species in the genus Castanea Mill. are one of the worthwhile species in the Hyrcanian forest of west Guilan (N Iran) with low region such as Siahmazgi, Ghalerodkhan and Visrod. that do not have good condition by reason of human interfering and disease. They have varying economic importance as nut tree crops, therefore, DNA barcoding technique can be a straightforward method for taxonomic statu...
