Land use for animal production influences the earth system in a variety of ways, including local-scale modification to biodiversity, soils, and nutrient cycling; regional changes in albedo and hydrology; and global-scale changes in greenhouse gas and aerosol concentrations. Pasture is furthermore the single most extensive form of land cover, currently comprising about 22-26% of the earth's ice-...

Shrub encroachment in arid and semiarid rangelands, a worldwide phenomenon, results in a heterogeneous landscape characterized by a mosaic of nutrient-depleted barren soil bordered by nutrient-enriched shrubby areas known as ‘‘fertile islands.’’ Even though shrub encroachment is considered as a major contributor to rangeland degradation, little is known about mechanisms favoring the reversibili...

In the mountainous rangeland of inland arid regions of Eurasia, seasonal grazing has been important to local communities for production of food, fiber, and for income, for the past thousand years. Recent population increases and other changes have put traditional grazing systems under pressure. However, empirical data describing soil properties or the impact of traditional grazing practice on t...

Based on the Project report of Determination Rangeland Availability and Range Status Classes carried out by Management Eastern Anatolia Agricultural Research Institute, eleven districts Çanakkale are ordered in terms rangeland quality. For this reason, four different rankings were obtained AHP, TOPSIS, VIKOR WASPAS methods. According to made methods, while district with highest quality was Biga...

Prescribed rangeland burning in April is a long-standing practice in the Flint Hills region of eastern Kansas to maintain the tallgrass prairie ecosystem. The smoke plumes originating from these fires increases ambient PM2.5 concentrations and potentially contributes to ozone (O3) exceedances in downwind communities. Source apportionment research using Unmix modeling has been utilized to estima...

Study area was selected from Talou farm to Chahjam Kavir in Damghan. Several plant types were distinguished in mentioned site. The types were Artemisia herba alba-Pteropyrum olivieri, Anabasis aphyllaLycium depressum, Tamarix. spp.-Halocnemum strobilaceum, Ha. strobilaceum Halostachys bellangeriana, Ha. strobilaceum-Limonium iranicum. In each plant type, three dominant plant species were select...

Aims Natural N abundance provides integrated information about nitrogen (N) input, transformation and output, indirectly reflecting N cycling traits within terrestrial ecosystems. However, relationships between natural N abundance and N cycling processes are poorly understood in China. Here, our primary objectives were to (i) examine the effects of grazing at varying levels of intensity on dN o...

The Grasshopper Integrated Pest Management Project (GHIPM) WDS a S15 million projccllhat lasted from 1986 La 1994 to identify, develop, and implement rangeland grasshopper management tactics within the Framework of Integrated Pest Management (lPI\'I) in the western United Stales. Computer simulation has been used La fulfill many original objectives for GHIPM and help bridge the gap between theo...
