Introduction: One of the most important challenges in climatic studies of Iran is the lack of access to long-term climatic data for all regions; among such regions, one can point to Dena region. This region is in the central Zagros, parts of Isfahan province, ChaharMahal and Bakhtiari, Fars...

Trees can record the long-term effects of climate variables. With the help of dendroclimatology knowledge, these variables can be reconstructed, especially for areas with short-term climatic data. For this purpose, in this study, six forestry plans were selected by using the thickness of Iranian...

Since long time ago, researchers in the fields of wood science, dendroclimatology and tree physiology has been interested in the variation of tree-ring width and vessel features within a tree. However, mutual relationship and interplay between these anatomical features were not adequately studied....

By comparing the pattern of narrow and width rings among the trees in one area, the exact year of each rings could be determine. This is the base of Dendrochronology. In this study, according to the important role of Juniper (Juniperus polycarpos) trees, an investigation have been done on variation ...

Dendrogeomorphology is one of the most important techniques for determining the age of geomorphological processes such as slope movements, flooding, erosion, earthquakes and other processes. One advantage of application of dendrogeomorphology in the estimation of gully erosion is that it can...

Trees respond to environmental and climatic changes during their biological life. Tree rings study is one way to discover these responses called dendrochronology. The most effective climatic factors which affect tree rings are temperature and precipitation. Present study aimed at investigating the...

Plants such as tree species respond to their surrounding environmental variations over their biological life cycle. One of the techniques to study the tree response to environmental conditions is dendrochronolog. In this study, 20 samples were prepared from 10 Zelkova carpinifolia trees in...

In this research study, tree rings widths of beech tree, obtained by the cores, from different elevation were analyzed, to study variability in Fagus orientalis Lipsky. This investigation provides a new approach to use Dendro-Genetic Method in line of dendrochronology to recognize phenotypic...

According to the results of the current research, a new approach in application of dendrochronology, using broadleaved tree rings, as main element of productivity, to evaluate forest ecosystem productivity, has been introduced. In this investigation, tree ring widths of sample cores which have been ...

This study was carried out in the oriental beech communities in order to investigate the natural regeneration and assessment of radial growth trend from 1960 to 2016. In each area, 50 1000-m² circular plots were established based on a random-systematic method. Regeneration was sampled on two...
