Overexploitation and climate change accelerate the degradation of Jordan's arid rangelands. Uncovered crusted soils increase runoff erosion hinder emergence native vegetation. Micro water harvesting combined with shrub-seedling plantation have been widely applied to reverse land trends. However, consequential soil vegetation dynamics rarely assessed, which constrains further out-scaling rehabil...

The Mediterranean climate prevailing on the coastal belt of the Mediterranean Sea undergoes to change toward the inner part of the Anatolia in accordance with the increase of altitude, mountain range barriers, the tectonic structure of the region, and tectonic-karstic depressions. Continentality also plays a critical role in the micro-climates that prevail across the various eco-regions. This s...

Soils are a pivot of sustainable development. Yet, urban planning decisions persist in compromising the usability soils resource. Urban land cover expansion to accommodate an increasing population results soil sealing. Concealment and physical obstructions prevent populations from engaging with their dependency. The concept connectivity recognises that nurturing mutually beneficial soil–society...

At least potentially karstifiable rocks cover much of the surface of Egypt and northern Libya. Study of caves and other karstic features of this region has been hampered by lack of roads, rapid disintegration of the surface of friable, poorly consolidated limestone, wind-blown sand and other factors. Interbedding with marly aquicludes hampers speleogenesis locally. Calcareous and evaporite kars...

The Miscellaneous Crenarchaeotic Group (MCG) is an archaeal lineage whose members are widespread and abundant in marine sediments. MCG archaea have also been consistently found in stratified euxinic lakes. In this work, we have studied archaeal communities in three karstic lakes to reveal potential habitat segregation of MCG subgroups between planktonic and sediment compartments. In the studied...

The 80,000 inhabitants of the lower part of Le Havre obtain their water supply from two karstic springs, Radicatel and Saint-Laurent. Until 2000, the Radicatel water was settled when turbidity exceeded 3 NTU, then filtered and chlorinated, whereas the Saint-Laurent water was simply chlorinated. Our study aimed to characterize the link between water turbidity and the incidence of acute gastroent...

درک الگوی توزیع مکانی ماکروفون خاک بدلیل اثرات آن روی فرآیندهای اکوسیستم بسیار مهم است. لیکن اطلاعات کمی در این خصوص وجود دارد. درمورد تنوع زیستی ارگانیسم ها وجانداران خاکزی که ازاجزای مهم وکلیدی درهرسیستم اکولوژیکی هستند و در بهبود حاصلخیزی خاک و تولیدات زمین وپایداری اکوسیستم ها(ازطریق فرآیندهای بیولوژیک)نقش عمده دارند تحقیقات کمی انجام شده است. این تحقیق جهت بررسی الگوی مکانی پارامترهای تنوع...
