摘要

本文研究了二维离散食饵-捕食者模型的动力学、恐惧的影响和食饵种群中的Allee现象。对平衡点及其稳定性进行了全面的分析,并探讨了分岔现象,包括Flip分岔和neimmark - sacker分岔。研究了复杂网络相互作用对系统动力学的影响。数值模拟表明在一定的参数条件下存在混沌行为。为了解决这种不稳定性,采用了OGY混沌控制方法对混沌进行调节,使系统稳定。研究结果对恐惧效应、Allee阈值和网络结构如何影响生态系统提供了有价值的见解,增强了对捕食者-猎物关系中种群稳定性和混沌波动的理解。

Modeling and managing chaos: a fear-affected discretized prey–predator system with Allee Effect

This paper investigates the dynamics of a two-dimensional discretized prey–predator model, the effects of fear, and the Allee phenomenon in prey populations. A comprehensive analysis of equilibrium points and their stability is conducted, along with exploring bifurcation phenomena, including Flip and Neimark–Sacker bifurcations. The influence of complex network interactions on system dynamics is also examined. Numerical simulations reveal the presence of chaotic behavior under certain parametric conditions. To address this instability, the OGY chaos control method is applied to regulate chaos and stabilize the system. The results offer valuable insights into how fear effects, Allee thresholds, and network structures influence ecological systems, enhancing the understanding of population stability and chaotic fluctuations in predator–prey relationships.
