Figure 4: Influence of dispersal rate on biomass density change. The relative change in biomass of fish functional groups obtained in the three analysed MPAs after 20-year simulation using Ecospace model under no fishing scenario was combined and grouped into five classes according to the dispersal rates (shown on x axis). The four panels group the functional groups by trophic level ((a) 2–2.5; (b) 2.5–3; (c) 3–3.5; (d) >3.5) Box plots (grey: adults and yellow: juveniles) are drawn to show the range in biomass change.
