  • Fig. 1 Model-averaged importance of the predictors of the CO2 fertilization effect on total biomass.

    The importance is based on the sum of Akaike weights derived from model selection using AICc (Akaike’s Information Criteria corrected for small samples). Cutoff is set at 0.8 (dashed line) in order to differentiate among the most important predictors.

  • Fig. 2 Overall effects of CO2 on plant biomass.

    (A to C) Effects on (A) total, (B) aboveground, and (C) belowground biomass for two types of mycorrhizal plants species (AM and ECM) in N-limited experiments (low N) or experiments that are unlikely N-limited (high N). Overall means and 95% confidence intervals are given; we interpret CO2 effects when the zero line is not crossed.
