Diffusion driven complex dynamics of Bazikin's type prey-predator model in presence of Allee effect in prey and...

This study explores the complexities of Bazikin's type predator-prey model, incorporating the influence of the mate-finding Allee effect on prey population, the impact of cooperative hunting strategies among predators, and the effect of diffusion. It provides a detailed analysis of how these factors influence ecological interactions and affect species dynamics. A detailed theoretical study is carried out to investigate the possible equilibrium states of the temporal model system. This is followed by an analysis of their stability and instability, along with an in-depth analysis of all possible bifurcation scenarios related to various equilibrium points. This model demonstrates saddle-node, Hopf, and Bogdanov-Takens bifurcations about some model parameters. On the other hand, the positivity and boundedness of solutions of the diffusive model are studied. The dynamics of the diffusive model have been investigated, considering linear as well as non-linear analysis. A qualitative analysis using numerical simulations is performed to validate all analytical findings. Numerical simulations demonstrate the development of diffusion-driven patterns, highlighting the emergence of target patterns, chaotic patterns, spots, stripes, and intricate combinations that merge stripes with spots. The simulation outcomes of the diffusive model indicate that multiple factors, including the predator's attack rate, the Allee effect, cooperative hunting behaviors, and diffusion coefficients, shape spatial distributions. The results of the analysis will help us to explore the relevance of various ecological effects and their impact within biology.
