Ecosystems gain carbon through the photosynthetic uptake in plants. All CO₂ enters the plants through stomata in the leaves. The optimizations of the plant atmospheric gas exchange in response to environmental changes are mediated by feedbacks affecting the degree of stomatal opening. Therefore measures of stomatal conductance and of stomatal behaviour are of great importance for scaling a range of parameters (e.g. net photosynthesis, transpiration and water use efficiency). Responses to increased CO₂, warming, drought and their combinations are investigated on the CLIMAITE field site. Measurements of the range, responsiveness and short time acclimation will support the analysis. A detailed analysis of stomata behaviour to increased CO₂, temperature and drought will be supported by supervision through all steps of the project.
