摘要
A model for the effects of a predator on a genetically distinguished prey population is formulated and investigated. The predator-free system settles at an equilibrium which can be destabilized by the predators if a suitably defined parameter, the predator invasion number, exceeds a threshold. The system can then coexist at a stable equilibrium or via persistent oscillations.
