Photosynthetic carbon isotope discrimination in trees: observations, predictions, and drivers

Abstract: Under elevated CO₂, photosynthetic carbon isotope discrimination is expected to increase in response to photosynthesis stimulation driven by the growth of atmospheric CO₂. While this response is widely documented in laboratory, field experiments and short-term observations, long-term proxies indicate that such response is not universally observed in forested ecosystems.
