研究带有年龄结构的捕食者-食饵模型的渐近行为.本文所研究的模型假定捕食者从幼年阶段到成年阶段的转变率依赖于幼年种群的密度,还假定幼年捕食者捕食食饵.本文最终给出了有年龄结构的捕食者-食饵模型的捕食者持久和灭绝的若干条件.
This paper studies the asymptotic behavior of a predator-prey system with age structure.It is assumed that the transition rate from immature stage to mature stage depends on the density of immature individuals.Also,the larva predator is assumed to consume prey.Conditions for the permanence and extinction of the predator are obtained.
