- For most of `realistic’ parameter values, NPZ long-time dynamics describes relaxation to a stable fixed point (coexistence of predators and preys) .
- For some `realistic’ parameter values, there is a stable limit cycle (P-Z oscillations à la Lotka-Volterra).
- For a large portion of parameter space, the stable fixed point dynamics is of the excitable type
