Ferula assa-foetida L. is an endangered and important medicinal plant in Iran. The knowledge of its ecological relationships will lead to plant conservation and reproduction objectives and better economic performance. This research was aimed to investigate the relationship between soil factors and plant morphology and oil components of the F. assa-foetida under habitat conditions in […]
Vegetation cover is one of the living components of terrestrial ecosystems and plays an important role in many ecosystem processes that are strongly influenced by climatic events. Thus, meteorological droughts can significantly affect the vegetation cover, especially in arid and semi-arid regions where vegetation is more sensitive to environmental conditions. This study was conducted with […]
The effects of Range Management Plans (RMP) on soil and vegetation characteristics were studied in Eshtehard rangelands at Alborz province. The parameters of yield, canopy cover, range condition and trend, bulk density, Organic Matter (OM%), Nitrogen (N), Phosphorous (P) and Potassium (K) were estimated on soil samples in sites of Ghenzel Cheshmeh as RMP and […]
One of the influential tools concerning the rangeland and vegetation sciences is the technology of remote sensing and satellite data. Satellite data have played essential roles in preparing the needed information for studying the vegetation. Vegetation has been widely recognized as one of the best indicators for determining the land conditions. Using vegetation indices is […]
Environmental pollution with heavy metals is a global disaster that is related to human activities. This study was conducted to determine the extent of heavy metals accumulation by plant species in Lia industrial city (Qazvin, Iran) and to investigate the remediative capacity of native plant species grown in the contaminated soils. Soil and industrial wastewater […]
Understanding the plant species diversity could be used as an important indicator applied for the natural areas management. The aim of this study was to investigate the relationships between soil characterizes with distribution and diversity of plant in vegetation types in Karvan district (located in west of Isfahan province). For this purpose, three vegetation types […]
Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were […]
Plant life and food production for human closely depend on fertile and healthy soil. Knowledge about qualitative properties of soil and its potential production can contribute us in the plantation, fertilization, utilization and land management. In addition, Rangelands cover a very large portion of the earth’s surface and play an important role in food security […]
Species diversity, richness and biomasses (aboveground biomass) and their relationships are the key variables of ecosystems. This study was conducted to determine the relationship of Species Diversity (SD) and Species Richness (SR) with Above-Ground Biomass (AGB) at a local scale at 5 different habitats (shrubland, forbland, grassland, shrub-forbland and forb-shrubland) in Zagros mountains in west […]
This study was performed to evaluate the forage nutritive value of Cymbopogon olivieri before and after conducting the essential oil extraction in rangelands of Khuzestan province, Iran. In this study, the aerial parts of Cymbopogon olivieri were collected in flowering stage from 10 natural regions located in Khuzestan province in 2016. Regions included ChalGandali, TalkhabKalat, […]
