The combined study of carbon (C) and oxygen (O) isotopes in plant organic matter has
emerged as a powerful tool for understanding plant functional responses to environmental …

Understanding the short‐term responses of mesophyll conductance (gm) and stomatal
conductance (gsc) to environmental changes remains a challenging yet central aspect of …

The least‐cost economic theory of photosynthesis shows that water and nitrogen are
mutually substitutable resources to achieve a given carbon gain. However, vegetation in the …

Reduced stomatal conductance is a common plant response to rising atmospheric CO2 and
increases water use efficiency (W). At the leaf-scale, W depends on water and nitrogen …

Extreme climatic events, such as heat waves, cold snaps and drought spells, related to
global climate change, have become more frequent and intense in recent years. Acclimation …

Water use efficiency (WUE) represents the trade‐off between carbon assimilation and water
loss in plants. It remains unclear how leaf stomatal and photosynthetic traits regulate the …

Evaluating leaf day respiration rate (RL), which is believed to differ from that in the dark (R
Dk), is essential for predicting global carbon cycles under climate change. Several studies …

Carbon isotope discrimination (∆) in leaf biomass (∆ BL) and tree rings (∆ TR) provides
important proxies for plant responses to climate change, specifically in terms of intrinsic …

Large trees in plantations generally produce more wood per unit of resource use than small
trees. Two processes may account for this pattern: greater photosynthetic resource use …

Increases in terrestrial water‐use efficiency (WUE) have been reported in many studies,
pointing to potential changes in physiological forcing of global carbon and hydrological …
