From: A global meta-analysis of woody plant responses to elevated CO2: implications on biomass, growth, leaf N content, photosynthesis and water relations

Fig. 2

Percentage change (± 95% CI) in photosynthetic characteristics (a–c) and water relations (d–f) of woody plants grown at eCO2. The whiskers denote 95% CI and the circles denote mean percentage change (MPC) between aCO2 and eCO2. The numbers above the major ticks of the X-axis denote number of observations. The area fill ( ) shows the trends and the magnitude of differences between the eCO2 concentrations. The wider the area the bigger the difference between MPCs
