Ferula pseudalliacea (Bitter asafetida) is an endemic medicinal plant grown in the center of Iran, which is used in pharmaceutical industries. There is less report about its habitat characteristics and distribution in Iran. So, this research was conducted to study the effects of topography and soil properties on distribution of this species in Yazd Province, […]
Rangelands are one of the most vulnerable parts concerning the climate changes‟ impacts. These impacts are even stronger in the arid and semi-arid areas where rangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out the actual dynamics of climate variations on the rangelands. The aim of this research was to determine […]
Abstract. The purpose of this study was to investigate the effects of topographical factors on the classification of grassland plant communities in the rangelands of Ghorkhud, Northern Khorasan Province, Iran. For sampling, land units were specified. A floristic list was prepared using minimal area method based on the nested plot (Braun-Blanquet method). 116 10m2 furrows […]
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We […]
One of the main objectives of ecosystem management is to preserve the species diversity. Many researchers regard higher species diversity as the stability of ecological systems. The aim of this study is to investigate the stability and relationships between topographical factors with diversity indices in Ghorkhud mountainous rangeland in northern Khorasan province, Iran. For data […]
Climate changes pose great threats to the main services of ecosystems such as food security, water security and health. This research was carried out in Haraz river basin rangelands, Mazandaran province in the north of Iran in 2015-2017 to analyze the perspectives of Haraz river basin (HRB) pastoralists about climate change. From 5236 local pastoralists, […]
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 […]
Salicornia herbacea is a sensitive species to seed shedding. In order to determine the effect of harvesting date on seed shedding, seed germination and seed oil production, an experiment was conducted in Gomishan Lagoon rangelands, Golestan province, Iran. Seed samples were harvested in twenty 1 m2 plots in 12 times since Nov 6th as the […]
The indigenous knowledge of shepherds about the different components of the plant fuel, ways of their classification and their contribution to fire behavior helps range managers to understand fire and effective management of the rangelands. The present research aims to document the indigenous knowledge of shepherds in this regard. For this purpose, a semi-structured interview […]
