Vetiver grass (Vetiveria zizanioides) is known to be survived under the diverse soil and water conditions. In order to study the effects of salinity stress on the seedling growth of the desired species, a completely randomized design was conducted with 3 replications. Seeds were sown in the salty-soil plots in the greenhouse. Salinity levels were […]
Dust storms are known as hazardous problems in western part of Iran. Iraq is one of the main sources for dust storm arriving to the western part of Iran. The Radial Basis Function Network model (RBFN) has been used to assess wind erosion hazards in the source area of dust storms over several western Iranian […]
Drought is a major problematic phenomenon mostly for semi-arid areas of Iran. During drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. Therefore, the assessment of drought effects on plant covers is the most important issue. This research was conducted in 2015 using the extracted vegetation indices […]
Ferula haussknechtii H. Wolff ex Rech.F. is an important medicinal plant belonging to the Apiaceae, family. In order to investigate the effect of Pb on the growth, chemical composition of essential oil and accumulation of metals in this species, a pot study was conducted under glasshouse condition. Seeds were collected from natural rangelands of Lorestan […]
In applied studies, the investigation of the relationship between a plant species and environmental variables is essential to manage ecological problems and rangeland ecosystems. This research was conducted in summer 2016. The aim of this study was to compare the predictive power of a number of Species Distribution Models (SDMs) and to evaluate the importance […]
