Globally, intrinsic water-use efficiency (iWUE) has risen dramatically over the past century in
concert with increases in atmospheric CO2 concentration. This increase could be further …

The terrestrial biosphere absorbs about 30% of the CO 2 emitted by human activities each
year. The persistence of such a carbon sink, however, depends on vegetation responses to …

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 …

Increase photorespiration and optimising intrinsic water use efficiency are unique
challenges to photosynthetic carbon fixation at elevated temperatures. To determine how …

The frequency of extreme drought events has been rising worldwide, but due to its
unpredictability, how plants will respond remains poorly understood. Here, we aimed to …

A central assumption in plant ecophysiology is that carbon is the primary currency for plant
fitness. To this end, plants are thought to maximize carbon gain and any deviations from …

Water use efficiency (WUE) is key to linking the water, carbon, and nutrient cycles in
terrestrial ecosystems. However, the coupling between WUE and leaf nutrients is still poorly …

The increasing occurrence of drought is a global challenge that threatens food security
through direct impacts to both plants and their interacting soil microorganisms. Plant growth …

Tree-ring stable isotopes provide insights into the drought-induced eco-physiological
mechanisms of forests. We investigated the growth of poplar and Mongolian pine trees …

The southwestern US is a global hotspot of climate change. Models project that
temperatures will continue to rise through the end of the 21st century, accompanied by …
