The dominant environmental driver of leaf water stable isotope enrichment differs for 2H compared to 18O

Archive ouverte | Cernusak, Lucas A. | CCSD

International audience. Several important isotopic biomarkers derive at least part of their signal from leaf water stable isotope composition (e.g., leaf wax δ2H, cellulose δ2H and δ18O, lignin δ18O). In order to in...

Preparation of starch and soluble sugars of plant material for the analysis of carbon isotope composition: a comparison of methods

Archive ouverte | Richter, Andreas | CCSD

International audience. Starch and soluble sugars are the major photosynthetic products, and their carbon isotope signatures reflect external versus internal limitations of CO(2) fixation. There has been recent rene...

Dynamics in respiratory δ 13 CO 2 of ecosystem components (soil, roots, and leaves) reveal insights into the regulation of respiratory metabolism and carbon allocation.

Archive ouverte | Unger, Stephan | CCSD

International audience. A thorough understanding of processes driving respiration and the metabolism of respiratory compounds is nowadays of major interest. Pronounced short-term dynamics in isotopic composition of ...
