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.
