Key to the long-term resilience of dryland ecosystems is recovery foundation plant species following disturbance. In with high interannual weather variability, understanding influence short-term environmental conditions on establishment essential for identifying vulnerable landscapes and developing restoration strategies. We asked how annual affect post-fire Artemisia tridentata, a shrub that d...
Soil microbial communities and nitrogen associated with cheatgrass invasion in a sagebrush shrubland
Cheatgrass invasion of Intermountain sagebrush steppe in the western United States poses increasing challenges to function and survival this native ecosystem. The invasive success persistence cheatgrass has been attributed soil total nitrogen, but mechanisms behind remain inconclusive. We hypothesized that microorganisms play a role nitrogen associated with invasion. collected samples from root...

This research aims describe patterns variation the species composition Dhofar, Oman examine causal environmental factors. Study area: Jabal Qamar mountain range, Oman. Methods: Hierarchical cluster analysis indicator were used identify variants forest. Topoclimatic factors, v...
Land use and Cover Changes (LULCC) are a major cause of environmental degradation in Sub-Saharan Africa (SSA) drylands hence serious problem to sustainable utilization development those lands. Involving communities their detection identification can empower convince them the importance adopting practices that minimize undesirable impacts. In this study, we applied GIS assisted community partici...
In recent years, remote sensing technology has enabled researchers to fill the existing statistics and research gaps on evapotranspiration in different land use classes. Thus, a remotely sensed-based approach was employed investigate how rates changed use/cover classes across Lake Urmia Basin from 2016 2020. This accomplished by applying Surface Energy Balance System (SEBS) maximum likelihood a...
The purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof Nodushan, Yazd. The plant species cover and the environmental variables were measured at 9 sites. Soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. Vegetation was classified using twowayindicator species analysis (TWINSPAN). Data was analyzed u...
