| Description |
Do the nonlinear terms arising from mortality or self-grazing of zooplankton have significant effect in suppressing limit cycles or auto-oscillations of marine ecosystem models that are observed under certain conditions? This question is examined with the help of the phase-plane analysis of a class of basic marine ecosystem models. It is found that even a rather small nonlinear term describing nonlinearity in mortality or self-grazing can effectively alter the linear stability conditions and thereby suppress the limit cycles.
