AB - <jats:p><p>Understanding the mechanisms underlying changes in carbon isotope discrimination (&#916;<sup>13</sup>C) in C<sub>3</sub> and C<sub>4</sub> plants is critical for predicting the C<sub>3</sub>/C<sub>4</sub> fraction in mixed ecosystems. Variations in &#916;<sup>13</sup>C are closely related to changes in the stomatal limitation of photosynthesis (i.e. the ratio of leaf internal to ambient partial pressure of CO<sub>2</sub>, <em>c</em><sub>i</sub>/<em>c</em><sub>a</sub>), which are in turn determined by environmental variables, but also depend on the pathway of carbon assimilation. For instance, isotopic fractionation during the diffusion of CO<sub>2</sub> through the stomata primarily influences &#916;<sup>13</sup>C in C<sub>4</sub> plants, while fractionation during Rubisco carboxylation has a stronger imprint on &#916;<sup>13</sup>C in C<sub>3</sub> plants. As a result, C<sub>3</sub> plants are depleted in <sup>13</sup>C compared to C<sub>4</sub> plants. Isotopic measurements can thus be used as tracers of physiological processes in plants.</p&am
