Cooperative behavior is an extensive mechanism in nature, and seen in several organisms, from bacterial cells to primates. In this paper, we have investigated a spatial predator–prey model with hunting cooperation in predators. Using linear stability analysis, we obtain the condition for diffusive instability and identify the corresponding domain in the space of control parameters. Using extensive numerical simulations, we obtain complex patterns, namely, spotted pattern, stripe pattern and mixed pattern in the Turing domain, by varying the hunting cooperation rate in predators and ratio of diffusion coefficient. The results focus on the effect of hunting cooperation rate in pattern dynamics of a diffusive predator–prey model and help us in better understanding of the dynamics of the predator–prey interaction in real environment.

捕食者中具有合作行为的扩散捕食者-猎物系统的空间模式动力学

合作行为在自然界中是一种广泛的机制,在从细菌细胞到灵长类动物的多种生物中都可以看到。在本文中,我们研究了一种空间捕食者 - 猎物模型,其中捕食者具有狩猎合作。使用线性稳定性分析,我们获得了扩散不稳定性的条件,并确定了控制参数空间中的相应域。通过广泛的数值模拟,我们通过改变捕食者的狩猎合作率和扩散系数的比率,获得了图灵域中的复杂图案,即斑点图案、条纹图案和混合图案。结果侧重于狩猎合作率对扩散捕食者 - 猎物模型的模式动力学的影响,并帮助我们更好地理解真实环境中捕食者 - 猎物相互作用的动力学。
