Harvesting of dynamically complex consumer–resource systems: Insights from a threshold management policy

Consumer–resource systems may present complex dynamical behavior due to multiplicity of steady states, initial conditions and/or critical parameter values. Threshold policies are one of the strategies employed to exploit these systems. It is shown that proper combinations of the threshold densities and harvesting effort intensities based on virtual equilibrium can yield desirable results from the management point of view despite the possible dynamical complexities in single as well as in multi-species population models.
