Figure 4: Rate of change in species richness and biomass. Rates of change (slopes) on control (dashed lines) and fertilized plots (solid lines) on species and biomass change. Thick lines show the overall effect estimate (mean overall rate of change in NPK plots) of each response (slopes from Figure 3), and thin lines represent the variation in the posterior distribution (uncertainty) sampled from each overall effect estimate within the 95% credible intervals (n=50 samples). Effects can be plotted in any order but here we start with losses for visual clarity.
