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 […]
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 […]
This study focuses on the evaluation of the chemical composition and in vitro nutrient digestibility of two forage legumes namely, Sulla aculeolata subsp. aculeolata and Sulla aculeolata subsp. mauritanica. from the semi-arid rangelands of the Mediterranean area. For the first time, a study has been conducted to determine the nutritive value of these two pasture forages. Plants […]
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 […]
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 […]
Satureja khuzistanica Jamzad is an endemic medicinal plant which grows naturally in arid rangelands of south west of Iran. It is also being cultivated in arid regions with salt problems. So,it is necessary to find a method to develop its cultivation under salinity condition. This study was aimed to determine effects of 24-epibrassinolide(EBL) in three […]
The role of different plant covers (i.e. Artemisia aucheri Boiss, Cousinia commutate Bunge and Agropyron longiaristatum Boiss) in topsoil properties and Nitrogen transformation is less known under semi-arid mountains. The main objective of this research was to study the effect of land covers on topsoil properties and nitrogen transformation. The study was carried out for […]
The study was conducted in the Butana region of Sudan to assess the impact of climate change on the browse trees/shrubs cover and production in the Butana rangelands. Five meteorological stations surrounding Butana were selected to represent the region’s climate. Simple regression analysis was used to analyze the trend of climate variables (rainfall, temperature). The […]
Climate change is one of the most serious threats to rangeland. The implications of climate change on the rangelands conditions of the Duda and Gomole in Southern Ethiopia were examined. Measurements of rangeland were made using field survey and focus group discussions. Descriptive statistics, one way ANOVA was employed to detect whether significant difference exists […]
Aromatic and medicinal plants are a rich source of substances that are beneficial to human health. At a socio-economic level, the exploitation of medicinal plants constitutes an important income for the local populations. However, the use of these plants in recent decades has put a lot of pressure on these resources, and many species suffer […]
