Herbivore community function shapes resilience and bistability of coral reefs
Fig 5
Interaction of turf and macroalgal dominance and herbivore community composition on coral reef recovery from disturbance.
Heatmaps showing how initial cover of turf and macroalgae affect final coral cover for fishing pressures ranging from 0 to 0.6 (rows) and for initial herbivore proportions set to 1 of 3 scenarios: 1) browser-dominated (A-C): browsers = 0.6, generalists = 0.15, grazers = 0.15; 2) grazer-dominated (D-F): grazers = 0.6, generalists = 0.15, browsers = 0.15, or 3) generalist-dominated (G-I): generalists = 0.6, grazers = 0.15, browsers = 0.15;. Total initial benthic cover is restricted to 0.85, and initial coral cover (Ct=0) = 0.15; therefore, the amount of unoccupied space changes for each combination of initial turf and macroalgae abundance. See Fig 3 caption or Table B in S1 Appendix for other parameter values.
