TL;DR: In this paper, the authors determined the δ18O values of water from small tributaries along the Seti River and Kali Gandaki in the Nepal Himalaya and found that δ 18Omw values decrease with increasing altitude for both transects.

TL;DR: Results indicate that system CO2 efflux strongly controls whole-ecosystem carbon exchange during precipitation pulses, and understanding the mechanistic relationships between the soil characteristics, plant ecophysiological responses, and canopy structural dynamics will be important for understanding the effects of shifting precipitation and vegetation patterns in semi-arid environments.

TL;DR: The current state of knowledge of stable isotope enrichment of leaf water, and its relevance for isotopic signals incorporated into plant organic matter and atmospheric gases is reviewed.

TL;DR: Net ecosystem exchange of CO(2) (NEE) and evapotranspiration (ET) before, and for 15 d following, experimental irrigation in a semi-arid grassland during June and August 2003 is estimated to alter NEE and ET dynamics with consequences for PUE(e) in water-limited ecosystems.

TL;DR: The use of trees from both the Chuska and San Mateo mountains, but not from the San Pedro Mountains, as early as A.D. 974 suggests that selection of timber sources was driven more by regional socioeconomic ties than by a simple model of resource depletion with distance and time.
