Abstract: The carbon isotope ratio (δ13 C) in tree rings is commonly used to derive estimates of the assimilation-to-stomatal conductance rate of trees, i.e. intrinsic water use efficiency (iWUE). Recent studies have observed increased iWUE in… read more here.

DOI: 10.3390/f9100642
Abstract: Intrinsic water-use efficiency (iWUE) is affected by the balance of photosynthetic rate, stomatal conductance, and climate, along with many other exogenous factors, such as the CO2 concentration in the atmosphere (CO2atm), nutrients, and water holding… read more here.
