Figure 3.

Histogram showing the distribution of extinction times in a nearest-neighbor and a mass-action setting for one particular parameter combination of the parameter space explored in the agent-based model, figure 2. For this parameter combination, the persistence time in the mass-action setting is about 3 orders of magnitude longer than that in the nearest-neighbor setting. Parameters were as follows: R = 0.1; B = 0.001; A = 0.000025; D = 0; N = 30 × 30. Initial conditions are the same as in figure 2a.
