Supervised machine learning and genotype by trait biplot as promising approaches for selection of phytochemically enriched genotypes.

Sumac is considered as a medicinal and industrial plant. Climate change threats natural ecosystems and hence, evaluation of sumac's genetic diversity, identification of superior genotypes, and conservation of such materials is important. In this study, 5 wild populations of sumac were investigated.

Forest conservation mediating soil quality relationship with diversity of various plant layers in the biosphere of Arasabran, Iran.

The link between biodiversity and ecosystem multi-functionality is an ongoing concern in ecological studies. Ecologists have focused on soil quality (SQ) as an ecosystem function and its relationship to biodiversity. Developing an appropriate and sensitive soil quality index (SQI) is critical, but it is severely restricted particularly in the forests.

Evaluation of hackberry (Celtis australis L.) fruits as sources of bioactive compounds.

Hackberry (Celtis australis L.) is native to the Mediterranean region and is distributed in Europe, Turkey, North Africa, and Iran. To the best of our knowledge, no study has been conducted on C.

Toward the identification of molecular markers associated with phytochemical traits in the Iranian sumac ( L.) population.

Sumac ( L.) is one of the important forest species dispersed in the northwest of Iran. It is one of the important spice in Iran and the Middle East because of active components containing organic acids, phenolic acids, flavonoids, anthocyanins, tannins and terpenoids.

Economic sustainability assessment in semi-steppe rangelands.

This study was conducted to determine indices and components of economic sustainability assessment in the pastoral units of Sahand summer rangelands. The method was based on descriptive-analytical survey (experts and researchers) with questionnaires. Analysis of variance showed that the mean values of economic components are significantly different from each other and the efficiency component has the highest mean value (0.

Investigation and comparison of natural regeneration structure of forest stands in protected and non-protected areas in Arasbaran.

In this study, a part of Arasbaran forest stands in two protected and non-protected areas have been compared for quantitative and qualitative factors of regeneration. Thus, using aerial photographs of 1967 in the scale of 1:20000, the similarity of these stands was examined and the comparable stands were chosen. Afterward, 77 circle plots of 0.

Studying the results of two methods of harvesting after a period of forest management plan.

To study the results of interference of strip cutting and single selection systems during the performance of the plan (1993-2003) in the Janbe Sara district, raw data which was collected during two years were compared together. Inventory was done in systematic random way and intensity of 3.3% in both years.
