Climate change reduces extent of temperate drylands and intensifies drought in deep soils
Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in extent and aridity in coming decades, temperature and precipitation forecasts vary by latitude and geographic region suggesting different trajectories for tropical, subtropical, and temperate drylands. Uncertainty in the future of tropical and subt...
متن کاملAssessment of drought and landuse changes: Impacts on groundwater quality in Shabestar basin, North of Lake Urmia
Management of groundwater quality is very important in arid and semi-arid areas. In this study, satellite images from TM, ETM and OLI sensors were used to evaluate the impacts of land use changes on groundwater quality for 1990, 2007 and 2015 in Shabestar basin. After processing and analyzing images, the basin was classified into five land use classes including pasture, bare land, farming, gard...
متن کاملDrought Impacts on Tree Growth and Mortality of Southern Appalachian Forests
The Coweeta LTER Program represents the eastern deciduous forests of the southem Appalachian Mountains in the United States. Coweeta Hydrologic Laboratory was established in 1934 and hence has a long record of climate measurement and vegetation response to both natural and human disturbance (Swank and Crossley 1988). The general climate of the area is classified as marine humid temperate becaus...
متن کاملEarly indications of drought impacts on forests in the southeastern United States
In the southeastern United States, drought can pose a significant threat to forests by reducing the amount of available water, thereby stressing trees. Destructive changes in crown conditions provide the first visible indication of a problem in a forested area, making it a useful indicator for problems within an ecosystem. Forest Health and Monitoring (FHM) and Palmer’s Drought Severity Index (...
متن کاملNitrate Dynamics in Riparian Forests: Groundwater Studies
This study was conducted to assess the removal of groundwater nitrate (NOa-) in different soil drainage classes within three riparian forests located in Rhode Island. A solution of NOa-and a conservative tracer [either bromide (Br-) or chloride (CI-)] was applied in growing and the dormant seasons to trenches upgradient of wetland locations with hydric soils (poorly and very poorly drained soil...
