Droughts can influence forest composition directly by limiting water or indirectly by intensifying other stressors that affect establishment, growth, and mortality. Using community assemblages of eastern US tree species and drought tolerance characteristics assessed from literature, we examine recent drought conditions in relation to the spatial distribution of species and their tolerance to dr...

climate change that the human faces is a somewhat unavoidable phenomenon. successful management of water resources needs recognition and perception of climate change in order to cope with water scarcity. the water scarcity is created by natural forcings such as drought, which is affected by regional climate. in other words, variation of climate variables as a result of climate change leads to v...

Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...

Droughts can be characterized by their severity, frequency and duration, and areal extent. Depth-area-duration analysis, widely used to characterize precipitation extremes, provides a basis for evaluation of drought severity when storm depth is replaced by an appropriate measure of drought severity. We used gridded precipitation and temperature data to force a physically-based macroscale hydrol...
