Different indices of functional diversity as: functional richness (FRic), functional evenness (FEve) and functional divergence (FDiv), could help to understanding of the relationship between plant diversity and ecosystem function. Therefore, this study was aimed to evaluate changes in species diversity and functional diversity of vegetation under different grazing intensities in relation to soil physic-chemical properties […]
In the summer of 2019 digitally recorded climatic data of shelterbelts and open pastures were compared to create a database. Our aim was to clarify the extent to which the herding needs of free-range flocks in the pasture meet the climatic conditions of the shelterbelts. It is considered important to graze sheep in the grazing […]
Seedling establishment is a crucial stage in the restoration of degraded rangelands. The effects of sowing dates and bio-fertilizers on the growth and establishment of Thymus daenensis Celak (native) and Thymus vulgaris L. (introduced) were studied over two growth seasons at Islamic Azad University, Borujerd branch, Lorestan, Iran. The treatments consisted of four bio-fertilizers treatments […]
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 […]
Decision makers in fire management are faced with many alternatives and criteria. In decision making about the event of fire, various criteria including technical, economic, social and environmental criteria have to be considered simultaneously. Management to prevent and control fires in forests and rangelands will be effective if fire-prone areas and management identify and focus […]
The United States has substantial public lands owned and managed by the US federal government. The economic impact of those lands has been repeatedly demonstrated by numerous studies. In parts of the Western United States managing these lands has included legislative action by the United States Congress to assist previously devastated populations of wildlife, including […]
Environmental factors have huge impact on yield and distribution of plant species. For this purpose, the response of Dorema ammoniacum (Apiaceae( canopy cover to some environmental factors was investigated in its natural habitat in south of Sabzevar, Iran in 2018-2020. Generalized Additive Model (GAM) was used to investigate the response of this species to soil […]
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 […]
This study was designed to investigate adaptation of five vetch species in terms of their growth and yield performance under rain fed conditions at Dessie Zuria district, South Wollo Zone, Amhara Region, Ethiopia. An experimental trial was conducted using a randomized complete block design with four replications on three locations of Gelisha, Teabsite and Adey […]
Desertification is one of the main ecological and environmental problems in Iran. It is remarkably urgent to monitor and assess this phenomenon and its impact on ecosystem components such as vegetation covers to prevent and combat desertification. This study aimed to evaluate the Change Vector Analysis (CVA) method’s efficiency in assessing and monitoring desertification in […]
Despite its ecological importance, the wetland edge vegetation could be strongly affected by human factors e.g. heavy traffic. In order to investigate the impact of human traffic on vegetation characteristics and plant diversity, a research was conducted at the edge of Almagol wetland in the northern Iran in 2021. The assessment was carried out through […]
Halophytes have good potential for forage production and combating desertification in saline soils. The present research was aimed to investigate the effects of phenological stages (Vegetative, Flowering & Ripening) on the yield and quality of three halophytes, Atriplex leucoclada, Suaeda fruticosa, and Seidlitzia rosmarinus, in warm steppe rangelands, Khuzestan privince, Iran. Data were collected in […]
