   FIG. C1. (A) The spatial grid of Model 1 (the sea star, Oreaster reticulatus) simulations. The shaded area is the region of high food concentration. Stars represent randomly distributed sea stars. Each cell in the diagram represents 100 cells in the actual simulation grid. (B) Initial conditions of Model 2 (the urchin, Strongylocentrotus droebachiensis) simulations. The shaded region is the kelp bed (with initial biomass of 4 kg/m2); the dashed line is urchin density in the barrens and kelp bed regions.
