The rangelands, as one of the largest dynamic biomes in the world,have very capabilities. Regulation of greenhouse gases in the Earth's atmosphere,particularly carbon dioxide as the main greenhouse gases, is one of these cases.The attention to rangeland, as cheep and reachable resources to sequestrate thecarbon dioxide, increases after the Industrial Revolution. Rangelands comprise thelarge par...

background: essential oils as growth stimulant play an important role in improving intestinal microflora and morphological properties and immune system in broiler chickens. objectives: the aim of this study was to investigate the effects of artemisia sieberi oil on intestinal morphology, secum microflora and immune system in broiler chickens. methods: two hundred day-old broiler chickens (ross ...

this study analyzed the relationship between the vertical distribution of root biomass and soil organic carbon (soc)content in the arid shrub lands of semnan province in iran. three sites were selected based on differences in canopy coverof artemisia sieberi (5%, 10% and 15%). average density of shrubs, root biomass and soc were determined at differentdepths (0-20, 20-40, 40-60, 60-80 cm) in 20...

this research was conducted to investigate the relationships between soil(organic matter, potassium, phosphorous, sodium, fine gravel, soil texture, ec, lime,gypsum, nitrogen) and environmental (elevation, slope) factors with distribution ofvegetation types in rangelands of sabzdasht, located in bafgh, yazd province at 2012. forthis purpose, four vegetation types were selected as follows: artem...

carbon is the most important greenhouse element which sequestrates by photosynthesis procedure and is the easiest and cheapest way of decreasing atmospheric gas level. the vegetation cover that has woody texture is more capable for carbon sequestration. the most plant species of arid rangelands are the shrub growth forms. the purpose of this research was to assess carbon sequestration potential...
