s _’ .*_ _ Ripariaq zones have &en shown to be important in smcturing veflebrgte communities and in maintaining biodiversity. We examined the [email protected] riparian zones in structuring small mammal Fmmuniti% ‘in a southern Appalachian watershed at Coweeta Hydr$pgical Laboratory, Macon County, &Jorth Carolina. We established pitfall and live-trap grids i? three rep@tes each of seeps, firstorder,, seco...

Due to its consistent availability, acceptable natural quality, and ease of direct diversion the underprivileged population, groundwater is a vital source water supply. It can also be transported there more swiftly inexpensively. Exploring potential zones (GWPZs) maps therefore essential, especially in semi-arid environments with insufficient surface supplies. The research area assessed using g...

Abstract Determination of soil carbonate is important for numerous chemical and physical processes in arid semi‐arid zones. Here, we modify a conventional method to more easily determine active CaCO 3 (ACC) fraction soils. Unlike the where oxalate used up after reaction with determined by titration KMnO 4 , proposed uses difference between total analyzed before ACC. The compared well approach; ...

Abstract Egypt, a predominantly arid and hyper-arid country, is one of the environmentally most fragile regions world. The country became hot spot for climatic extremes aridity change in global warming context. unavailability detailed reliable climate zonation map major hindrance to studies Egypt. This study attempted generate high-resolution zone Egypt based on novel image analysis technique. ...

Abstract Climate zones fundamentally shape the patterns of terrestrial environment and human habitation. How global warming alters their current distribution is an important question that has yet to be properly addressed. Using root-layer soil moisture as indicator, this study investigates potential future changes in climate with perturbed parameter ensemble projections by HadGEM3-GC3.05 model ...

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 analyzed plant richness and diversity data from 75 sa...

To combat desertification and land degradation in arid semi-arid zones, the government has adopted an approach of rehabilitation pasturelands through forage plantations. This program was launched at beginning 1990s and, to date, there been no global or national study on sustainability program, particularly its economic profitability. Our work’s principal objective perform analysis plantation ac...
