Spatio-Temporal Assessment of Meteorological Droughts Effect on Vegetation Droughts in Khorasan Razavi Province, Iran

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 […]

Multivariate Statistical Method for Assessing Livestock Grazing Effects on Soil and Vegetation in Steppe Rangelands (Case Study: Steppe Rangelands of Saveh)

This study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. The study was carried out in steppe rangelands of Saveh, Markazi province, Iran. Four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. To study […]

Change of Species Diversity in Vascular Plants Across Ecological Species Groups

Biodiversity plays a crucial role in stability and productivity of natural ecosystem. The main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. Therefore, fifty different Land Unit Tracts (LUT) were identified in Khod-Neuk basin, Yazd province, Iran, in 2010. Vegetation and soil samples […]
