Evidence for distinct isotopic composition of sap and tissue water in tree stems: consequences for plant water source identification
A. Barbeta, R. Burlett, P. Martin-Gomez, B. Frejaville, N. Devert, L. Wingate, J.-C. Domec, J. Ogee
The paper shows that isotopic offsets between stem and source water can be explained by micrometer-scale water isotope heterogeneity in stems and soils, and introduces a technique to extract sap water separately from bulk stem water.
