  1. Trends of differences in the availability of light, water, and nitrogen between the control simulation, and the fixed CO2 (CO2_fixed), fixed precipitation (Prec_fixed), fixed temperature (Tair_fixed), and fixed shortwave radiation (Swd_fixed) simulations. The letters indicate the statistical significance of ratios of carbon allocation in the five simulations (p < 0.05)
  2. CO2 atmospheric CO2 concentration; Prec precipitation; Tair air temperature; and Swd incident shortwave radiation
  3. *indicates a statistically significant level (p < 0.05)
