The role of mesophyll CO₂ diffusion in modulating the response of photosynthetic carbon uptake to CO₂ enrichment of a mature temperate forest

This project seeks to refine our understanding of how mesophyll recistance (r_m) responds to environmental changes and whether plants can adjust r_m over time. By combining advanced experimental techniques with mathematical models, the study will examine both immediate and long-term acclimation to elevated CO₂. The insights gained will improve the representation of photosynthesis in land surface models (LSMs), reducing uncertainty in predictions of vegetation carbon uptake and strengthening our ability to model climate–carbon cycle interactions.
