Figure 2.

Model visualisation of the three-way interaction (species richness × temperature × CO₂) on MPB biomass. The interaction of temperature, CO₂ and species richness on MPB biomass (F₀^-15) at three constant temperatures (a) 6°C, (b) 12°C, (c) 18°C. In the visualisation, the CO₂ levels are represented as present-day 370 ppmv (solid line), 600 ppmv (dashed line) and 1000 ppmv (dotted line).
