摘要

研究了由白噪声、有中心泊松噪声和无中心泊松噪声组成的随机微分方程组驱动的具有Beddington-DeAngelies泛函数响应的非自治随机捕食者-猎物模型。证明了被考虑系统整体正解的存在唯一性。在考虑的随机捕食-食饵模型中,得到了种群密度的随机极限有界性、随机持久性、均值非持久性、均值弱持久性和强持久性以及种群密度灭绝的充分条件。

Dynamics of the Predator-Prey Model with Beddington-DeAngelis Functional Response Perturbed by Lévy Noise
We study the non-autonomous stochastic predator-prey model with Beddington-DeAngelies functional response driven by the system of stochastic differential equations with white noise, centered and non-centered Poisson noises. It is proved the existence and uniqueness of the global positive solution of considered system. We obtain sufficient conditions of stochastic ultimate boundedness, stochastic permanence, non-persistence in the mean, weak and strong persistence in the mean and extinction of the population densities in the considered stochastic predator-prey model.
