Carbon sequestration in rangeland ecosystems has been identified as a suitable strategy to offset greenhouse gas emissions that information of carbon sequestration hotspots is a good tool to improve rangeland management. Objectives for this study were to assessment potential carbon sequestration in various rangeland types, to identify carbon sequestration hotspots and to study the effective fact...

Plants exchange signals with other physical and biological entities in their habitat, a form of communication termed allelopathy. The underlying principles of allelopathy and secondary-metabolite production are still poorly understood, especially in desert plants. The coordination and role of secondary metabolites were examined as a cause of allelopathy in plants thriving under arid and semiari...

Some chemical characteristics of root, shoot and litter of index species such as Salsola rigida, Artemisia sieberi and Stipa barbata commonly used in rangeland development projects were evaluated and compared. Chemical properties of soil under and between the above mentioned species were also studied. For this purpose, vegetation types of Stipa barbata and Artemisia sieberi - Salsola rigida wer...

Astragalus L. is one of the largest angiosperm complex genera that belongs to family Fabaceae, subfamily Papilionoideae or Faboideae under subtribe Astragalinae tribe Galegeae. The current study includes whole plant morphology, DNA barcode (ITS2), and molecular marker (SCoT). Ten taxa representing four species were collected from different localities in Egypt during period February 2018 May 201...
