We consider here a food chain composed of four species with full omnivory with Lotka-Volterra dynamics. Conditions for uniform persistence and weak persistence of the food chain are derived. It is also shown that the system exhibits a heteroclinic cycle.
我们在此考虑一个由四个具有完全杂食性且服从洛特卡 - 沃尔泰拉动力学的物种组成的食物链。推导了该食物链均匀持续生存和弱持续生存的条件。还表明该系统呈现出一个异宿环。
