Analyses of stable isotopes (C, O, H) in tree rings are increasingly important cross-
disciplinary programs. The rapid development in this field documented in an increasing …

Fluctuations in glacier mass and volume are indicative of changes in the climate system.
They also strongly affect regional climate and hydrology. In this paper, we explore possible …

Tree-ring oxygen isotope (δ 18 O TR) is a powerful proxy for paleoclimatology, ecology and
archaeology, δ 18 O TR studies in Asia over the past∼ 50 years have made significant …

Elevated atmospheric CO2 concentrations are expected to enhance photosynthesis and
reduce stomatal conductance, thus increasing plant water use efficiency. A recent study …

The degradation of permafrost caused by climate warming accelerates the infiltration and
evaporation of water, destroys the hydrological system, and increases the drought stress of …

Rising atmospheric CO2 concentration (C a) is expected to accelerate tree growth by
enhancing photosynthesis and increasing intrinsic water-use efficiency (iWUE). However …

Little is known about whether increasing iWUE (intrinsic water use efficiency) can stimulate
tree growth in the temperature-limited natural timberlines. Here, we presented the basal …

Increasing air temperature and atmospheric CO 2 concentrations (C a) can profoundly affect
photosynthesis and intrinsic water-use efficiency (iWUE). However, the response of trees in …

Measurements of the stable carbon isotope ratio (δ 13 C) on annual tree rings offer new
opportunities to evaluate mechanisms of variations in photosynthesis and stomatal …

Tree-level intrinsic water-use efficiency (iWUE) is derived from the tree-ring 13C isotope
composition (δ13C) and is an important indicator of the adaptability for trees to climate …
