Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...

the present study describes approaches for the identification of individual beech trees using maternal tissues from their seeds or fruits. four microsatellite markers were used for genetic analysis of seedlots from fagus orientalis lipsky, a highly out-crossing tree species. seeds from 11 single-tree harvests belonging to one population, (7 seeds from each), as well as non-paranchymatic materna...

abstract. natural populations of carpinus orientalis mill. shrub lands occur mainly in high and middle altitudes of the hyrcanian forests, n. iran, particularly on steep rocks and forest outcrops. there are some discrepancies on the intra-specific delimitation of this important woody species. the aim of the current study was to examine the anatomical variation of stems and leaves of sixteen pop...

Aim To analyse the biogeographic patterns of Temperate Deciduous Forests (TDFs) in Western Eurasia based on different life-forms and forests layers explore their relationships with current climate, Last Glacial Maximum (LGM) climate topography. Location Eurasia. Taxon Vascular plants. Methods We delimited nine regions encompassing variability TDFs collected 1000 vegetation plots from each. deco...

In this study, the capability of Landsat-8 (L8), Sentinel-2 (S2), Sentinel-1 (S1), and their combination was investigated for estimating aboveground biomass (AGB). A pure stand Fagus Orientalis located in Hyrcanian forest Iran selected as study area. The performance a parametric approach, i.e., Multiple Linear Regression (MLR) model non-parametric approaches, k-Nearest Neighbor (k-NN), Random F...

effects of plant roots on increasing soil shear strength depend on root tensile strength. thus, determination of root tensile strength can provide the necessary data for analyzing root-soil relations. tensile strength of plant roots varied in a wide range and have been reported from thousands to millions of mpa. the main objective of this study was to assess inter-species variations of root ten...

Compacted soil has lower water infiltration and hydraulic conductivity, which contributes to increased runoff and erosion on slopes. The aim of the present study was to assess runoff and sediment on three skidding trail longitudinal gradients (15%, 25%, and 35%) and different levels of machine traffic (low, medium, and high), over a two-year period following the impact in the Hyrcanian forest, ...
