一类食饵有病的离散生态流行病模型的动力学

Dynamics of a discrete eco-epidemiological model with disease in the prey

Lopo F. de Jesus, César M. Silva, Helder Vilarinho

摘要:

利用Mickens非标准方法,得到了一类离散的非自治生态-流行病模型,该模型包含了相应于被捕食者的一般函数.我们得到的结果的持久性和灭绝的感染的猎物假设的二维捕食者-猎物子系统,描述的动态在没有感染满足一些假设。一些例子和模拟进行说明我们的结果。

英文摘要:

Using Mickens nonstandard method, we obtain a discrete family of nonautonomous eco-epidemiological models that include general functions corresponding to the predation of the infected and uninfected preys. We obtain results on the persistence and extinction of the infected preys assuming that the bi-dimensional predator-prey subsystem that describes the dynamics in the absence of the infection satisfies some assumptions. Some examples and simulations are undertaken to illustrate our results.
