Fig. 3. The effect of changing community dynamics on the CLS of the five-species system shown in Fig. 2A. Prediction-r2 spectra (based on analysis of densities of S5) were produced from series of five maps of the landscape commencing at generation 400 (before environmental change inducing a reduction in the growth rate of S5 at generation = 500) and, after the reduction in growth rate, commencing at generations 1000, 2000, and 3000. Consecutive maps in each series were separated by 10 time steps. The change in dynamics is reflected by a reduction in the CLS from about 75 to 50 length units. Areas identifying the CLS are shown as black horizontal bars.
