While in recent years, due to numerous reasons, the amount of travel and tourism has increased, the amount of problems caused by this activity is also considered by managers. By using presence points of tourists in Javanrud County, Analytic hierarchy process (AHP) and Random Forest (RF) models, the conditions of establishment of tourists from the aspect of land use planning was investigated. In...
Aboveground biomass (AGB) of forests is an essential component of the global carbon cycle. Mapping above-ground biomass is important for estimating CO2 emissions, and planning and monitoring of forests and ecosystem productivity. Remote sensing provides wide observations to monitor forest coverage, the Landsat 8 mission provides valuable opportunities for quantifying the distribution of above-g...
Examining the economic value of carbon sequestration in forests is essential, given the risk of global climate change, which has posed a profound challenge to societies internationally. The present study investigates the amount of carbon sequestration and its economic value in the oak forests (Quercus brantii L.) of Pahnus forest habitat with an area of 990 ha, located in Chaharmahal va Bakhtia...
in order to evaluate capability of the landsat-etm and irs-p6-liss iv images for canopy cover mapping a case study was done on the forests of javanroud in kermanshah province. after evaluation of the geometric and radiometric quality of the data, the etm+ images, the etm+ images were geometrically corrected with gcps and the images were registered with rmse error 0.46 and 0.48 pixels, for x and...
Phylogenetic relationships of Iranian Acanthodactylus species were investigated using 1407 bp of mitochondrial DNA including 606 bp of cytochrome b and 801 bp of NADH dehydrogenase subunit 4 (ND4). Analyses done with maximum parsimony, maximum-likelihood, and Bayesian inference included 67 specimens from 27 geographically distinct localities in Iran. Our molecular results proposed three clear a...
The agricultural transition profoundly changed human societies. We sequenced and analysed the first genome (1.39x) of an early Neolithic woman from Ganj Dareh, in the Zagros Mountains of Iran, a site with early evidence for an economy based on goat herding, ca. 10,000 BP. We show that Western Iran was inhabited by a population genetically most similar to hunter-gatherers from the Caucasus, but ...
The present study investigates the occurrence of wild grasses at Epipalaeolithic and aceramic Neolithic sites in the Near East in order to assess their role in subsistence economies alongside the emergence of cereal cultivation. We use Chogha Golan in the foothills of the central Zagros Mountains (ca. 11.7-9.6 ka cal. BP) as a case study, where the archaeobotanical data suggest the frequent exp...
The emergence of farming during the Neolithic transition, including the domestication of livestock, was a critical point in the evolution of human kind. The goat (Capra hircus) was one of the first domesticated ungulates. In this study, we compared the genetic diversity of domestic goats to that of the modern representatives of their wild ancestor, the bezoar, by analyzing 473 samples collected...
The semi-parasitic European yellow mistletoe (Loranthus europaeus Jacq.) is one of the harmful and damaging factors to the Zagros forests. This study to analyze the causes of infected trees by European yellow mistletoe was conducted in the Ghalajeh forests in Kermanshah province. To carry out this study, completely infected trees were examined by using the tree-to-tree sampling method. Required...
