Fire as an ecological factor has both positive and negative effects on components of the ecosystem. The aim of the present study was to investigate the effects of fire on composition, diversity, and functional groups changes in the Tangesorkh rangeland of Boyer-Ahmad County, Iran. The fire took place in the summer of 2015. Two years […]
There is an enormous stress on livelihood analysis of rural communities and their economies. Village common property resources (CPRs) have played a substantial economic role for the sustenance in rural areas of the drylands. The CPRs of drylands of western Rajasthan shows a varied range of habitats due to strong functional disparities in topographic, geomorphological, […]
Land use change as the most important destructive factor in natural ecosystems is a globally problem that changes soil properties. Therefore, correct management and recognition of change aspects on each component of the ecosystem is necessary. This process causes land destruction, ecosystem instability, soil erosion, and more biological threats. Due to increasing land use conversion […]
Since the halophytes species have an important role in such ecosystem balance and they have been grazed by livestock as supplementary forage, the awareness of livestock’s desire to grazing and their preference values of these species is of high priority. Regardless of the importance of halophyte species in the livestock feeding in Iran, there is […]
Species Distribution Modelling (SDM) is an important tool for conservation planning and resource management. Invasive species represent a good opportunity to evaluate SDMs predictive accuracy with independent data as their invasive range can expand quickly. Thus, the aim of this study was to investigate the relationships between presence of Leucanthemum vulgare Lam. and environmental variables […]
In order to study the effect of drought stress on seedling morpho-physiological traits of alfalfa (Medicago sativa), the seeds of ten populations were collected in their natural habitats from different parts of the Fars province, Iran in 2013. A factorial experiment was conducted using 10 alfalfa populations and four water stress treatments of 100, 75, […]
Soil salinity has concerned people in arid and semi-arid rangelands. One of the most essential cases in relation to information for natural resource managers is preparation of soil salinity maps. Developing such maps, using traditional methods spends a lot of time and costs. Satellite data have broadened and integrated our vision for this purpose. This […]
Abstract. Nowadays, in many rangelands, due to over grazing, and problems that some plants have in germination, the rate of forage production is greatly reduced. So to take advantages of the benefits of such plants, it is necessary to identify and remove barriers of germination and establishment of suitable plants. A study was carried out […]
The basis of many plant studies is the identification of plant species because identifying plant populations in every region is the pivotal pillar of plants conservation. Furthermore, study of the stages of plant growth cycle is one of the ways to determine growth details of any given plant. The current research aimed to investigate the […]
Wildfires annually occur as a threatening factor in natural resources at a large scale. This study was conducted with the aim of determining the effects of fire on the structural and functional characteristics of vegetation in the Kaboudeh range site, Kermanshah province, Iran during three years (2018-2020). An unburned range (control) was selected near the […]
