Abstract EN
A nonlinear system describing the interaction between toxin-producing phytoplankton and zooplankton was investigated analytically and numerically, where the system was represented by a couple of reaction-diffusion equations.
We analyzed the effect of self- and cross-diffusion on the system.
Some conditions for the local and global stability of the equilibrium were obtained based on the theoretical analysis.
Furthermore, we found that the equilibrium lost its stability via Turing instability and patterns formation then occurred.
In particular, the analysis indicated that cross-diffusion can play an important role in pattern formation.
Subsequently, we performed a series of numerical simulations to further study the dynamics of the system, which demonstrated the rich dynamics induced by diffusion in the system.
In addition, the numerical simulations indicated that the direction of cross-diffusion can influence the spatial distribution of the population and the population density.
The numerical results agreed with the theoretical analysis.
We hope that these results will prove useful in the study of toxic plankton systems.
