Appendix C. Combined results from the spatial simulation model and the visual census survey for the best fit of the observed fish size distributions in correspondence with a median dispersal distance of 10.7 km/yr.

Combined results from the spatial simulation model and the visual census survey for the best fit of the observed fish size distributions (R² = 49.3%) in correspondence with a median dispersal distance of 10.7 km/yr. The 140 km along the x-axis represents the entire coastline counterclockwise around the island starting and ending at Westpunt. (A) Observed reef fish counts from visual surveys along the coast of the island (dots). No surveys were conducted along the major part of the wave-exposed northern and eastern coast of the island (between 85 and 130 km from Westpunt). The solid line represents the simulated number of reef fish predicted by the model. (B) Simulated relative size distribution at a dispersal rate of 10.7 km/yr. (C) Observed relative size distribution from visual surveys. The size distribution in 2B and 2C is divided in 5 cm size classes: 15–19.9 cm; 20–24.9 cm; 25–29.9 cm; 30–34.9 cm; 35–39.9 cm; 40–44.9 cm; 45–49.9 cm, indicated by increasing color intensity from small to larger fish. Abbreviations for seagrass bays: PB = Piscadera Bay; SW = Spanish Water Bay; FB = Fuik Bay; AB = Awa blanku; AO = Awa di Oostpunt; SJ = St. Joris Bay; PG = Playa grandi.
