Stable carbon isotope ratios (δ13 C) of terrestrial plants are employed across a diverse
range of applications in environmental and plant sciences; however, the kind of information …

It has been 75 yr since leaf respiratory metabolism in the light (day respiration) was
identified as a low‐flux metabolic pathway that accompanies photosynthesis. In principle, it …

Abstract Models of vegetation function are widely used to predict the effects of climate
change on carbon, water and nutrient cycles of terrestrial ecosystems, and their feedbacks to …

The strong covariation of temperature and vapour pressure deficit (VPD) in nature limits our
understanding of the direct effects of temperature on leaf gas exchange. Stable isotopes in …

The terrestrial carbon and water cycles are intimately linked: the carbon cycle is driven by
photosynthesis, while the water balance is dominated by transpiration, and both fluxes are …

We revisit the relationship between plant water use efficiency and carbon isotope signatures
(δ 13 C) of plant material. Based on the definitions of intrinsic, instantaneous and integrated …

Stable carbon isotopes are used extensively to examine physiological, ecological, and
biogeochemical processes related to ecosystem, regional, and global carbon cycles and …

The partial pressure of CO2 at the sites of carboxylation within chloroplasts depends on the
conductance to CO2 diffusion from intercellular airspace to the sites of carboxylation, termed …

The three most commonly used methods for estimating mesophyll conductance (gm) are
described. They are based on gas exchange measurements either (i) by themselves;(ii) in …

Plant water‐use efficiency (WUE, the carbon gained through photosynthesis per unit of
water lost through transpiration) is a tracer of the plant physiological controls on the …
