备注:
We found an error in Theorem 3.9, and a new version with different title "Global Stability of the Periodic Solution of the Three Level Food Chain Model with Extinction of Top Predator"
In this work, we revisit the classical Holling type II three species food chain model with a different viewpoint. Two critical parameters $λ_1$ and $λ_2$ dependent on other six parameters are defined. We show that local stabilities and existence of all equilibria can be reformulated by $λ_1$ and $λ_2$, and the complete classifications of parameters and its corresponding dynamics are given. Three global extinction results are showed by comparison principle analytically. Moreover, some interesting numerical simulations, including the chaotic phenomena, and the bi-stability phenomena, including equilibrium-cycle bi-stability and cycle-cycle bi-stability, are presented numerically. Finally, a brief discussion and biological implications are given.

Dynamics of a predator-prey model with generalized Holling type functional response and mutual interference
相互干扰和猎物避难所是捕食者-猎物动力学的重要驱动因素。相互干扰的“指数”或程度在理论生态学中一直备受争议。本文研究了一类具有广义Holling型功能反应的捕食-食饵模型中相互干扰指数的相互作用。我们调查系统的稳定性,并推导出鞍结和Hopf分岔发生的条件。对于该模型,还得到了食饵种群灭绝的一个充分条件.此外,我们调查的猎物避难所对模型的种群动力学的影响,并推导出的猎物避难所,将产生持久性的人口的条件。我们通过数值模拟提供了额外的验证我们的分析结果。我们的研究结果与Gauss G. F(1934),这表明捕食者和猎物种群的灭绝是可能的在一个有限的时间段内-但引入避难所可以有效地导致持久性。
