Complex Dynamics in a Harvested Nutrient-Phytoplankton-Zooplankton Model with Seasonality

Figure 15

Corresponding Poincaré section of model system (2) with Γ=0.81 is plotted in (a), and corresponding Poincaré section of model system (2) with Γ=0.95 is plotted in (b). Poincaré points 5000–15000 are plotted.
