Fig. 5. Uncertainty analysis on the relative global losses of vascular plant species at equilibrium. Figure shows the uncertainty to a) the value of z as function of scale and the uncertainty in Island scale z-values (Monte Carlo analysis; 25–75% and 5–95% range are shown) and b) the effect of modifying the number of units distinguished in the analysis. This analysis is based on the Global Orchestration scenario. The uncertainty bars indicate the maximum and minimum values in the total set of scenarios.
