Abstract
Non-renewable resources and harvesting widely exist in biological systems. In this work, we present a detailed study on a predator–prey model including these two factors. We demonstrate that such system shows the property of bifurcations behavior, which is induced by non-renewable resources and harvesting. Furthermore, spatial effects are combined, and we obtain rich pattern dynamics. The obtained results reveal that non-renewable resources and harvesting play crucial roles in predator–prey interaction and may account for the ecological complexity in a real environment.
