Fig. A1. Maps of coral reef seascapes that were analyzed for openness. Scale bars are 10 km long and north is up. Each seascape has been simplified to a 500 × 500 m grid, and only grid cells with > 50% reef coverage were retained. Seascapes with sparse reefs < 500 × 500 m may look quite different after this processing (e.g., Glover's Reef in Belize). The gray shading is land.
Fig. A2. Openness (S) in a 1D array of patches with a Gaussian dispersal kernel displaced from zero to model advection. The Peclet number (kernel displacement/dispersal spread) is (a) 0.25, (b) 0.75, or (c) 1.5. Otherwise, compare to Fig. 2a.
Fig. A3. The exact level of openness (S) depended in part on the grid size used for the analysis. Larger grids tended to have lower S. The figures show: average S across all patches in a seascape (a and d), minimum S within a seascape (b and e), and maximum S within a seascape (c and f). Compare to Fig. 4. Top row shows NW Belep in New Caledonia. Lower row shows Kimbe Bay, Papua New Guinea.
