In the arid and semiarid regions of North America, discrete precipitation pulses are important
triggers for biological activity. The timing and magnitude of these pulses may differentially …

Aeolian processes affect the biosphere in a wide variety of contexts, including landform
evolution, biogeochemical cycles, regional climate, human health, and desertification. …

… (T), and evaporation of water intercepted by the plant canopy (I)—we refer them either
individually, collectively as ETI, or as ET when we are referring to the total of only E and T without …

Water availability limits plant growth and production in almost all terrestrial ecosystems 1 , 2
, 3 , 4 , 5 . However, biomes differ substantially in sensitivity of aboveground net primary …

Abstract Changes in Earth's surface temperatures caused by anthropogenic emissions of
greenhouse gases are expected to affect global and regional precipitation regimes. …

Widespread tree mortality associated with drought has been observed on all forested continents
and global change is expected to exacerbate vegetation vulnerability. Forest mortality …

Large-scale biogeographical shifts in vegetation are predicted in response to the altered
precipitation and temperature regimes associated with global climate change. Vegetation shifts …

Increases in the abundance or density of woody plants in historically semiarid and arid
grassland ecosystems have important ecological, hydrological, and socioeconomic implications. …

Arid ecosystems, which occupy about 20% of the earth's terrestrial surface area, have been
predicted to be one of the most responsive ecosystem types to elevated atmospheric CO 2 …

… quadratic polynomial was fitted as f(t) = c 1 + c 2 t + c 3 t 2 to all 2n + 1 points in the moving
window and the value y i was replaced with the value of the polynomial at position t i (ref. 24). …
