摘要
研究了具有Beddington-DeAngelis和Holling Ⅳ的功能反应的捕食与食饵生态系统,该系统是两个具有竞争关系的食饵种群被一个具有年龄结构的捕食种群捕食.运用比较定理,得到了系统持续生存和捕食者灭绝的充分条件。
A stage structured on predator-two competitive prey system with Beddington-DeAngelis and Holling Ⅳ functional responses has been presented in this paper. Based on the comparison theorem, some sufficient conditions are derived for permanence of the system and non-permanence of predators.
