This paper deals with such a class of predator-prey models that the predator, in addition to the prey considered, has other natural sources of food.

Her mother, a patient teacher, instructed Legadema in the skills she would need to survive as a predator: how to pin down prey and where to clamp on their throats with her jaws to suffocate them.
她的母亲是只有耐心的花豹，教导她成为一只懂得生存，而技术卓越的掠夺者；要等候在那处撂下猎物以及在喉头何处扣住使之窒息等。
The result leads to the permanence of the prey-predator systems, the instability of the trivial and all forms of semitrivial solutions, and the nonexistence of nonuniform steady-state solutions.
这个结果导致捕食食饵系统的持久性、平凡解和所有半平凡解的不稳定性和不存在非一致平衡解。
