A New Age-Structure Predator-prey Model With Cannibalism

报告摘要: This paper proposed a new age-structure predator-prey model with cannibalism, and studied the asymptotic behavior for this model. It is assumed that the transition rate from immature stage to mature stage depends on the density of immature individuals. Also, the mature predator can consume the immature predator. Conditions for the permanence and extinction of the predator are obtained.
