Numerical Simulation of Predator-Prey Patterns in Marine Organisms

This paper mainly investigates the application of predator-prey systems. By deriving the first-order principles of the stochastic partial differential equations, we analyzed the stability of the model at the equilibrium point. The coefficients of the outgoing amplitude equation were deduced using the Wakefield nonlinear analysis. The model was numerically simulated by setting parameters using the nine-point difference method, and the simulation results are in agreement with the numerical results. In addition, a marine predator-prey model combining the fear effect and refuge environment is proposed in this paper, and the pattern formation mechanism of species coexistence is revealed through theoretical analysis and numerical simulation.
