Motional Instabilities in Prey–Predator Systems

Differential fluxes can destabilize the locally stable stationary density distributions in interaction systems with diffusion, advection, and/or locomotion of chemical or biological species. By this method they can cause the formation of stationary or travelling spatial structures. Different scenarios of this general mechanism of spatio-temporal pattern formation in reaction–diffusion–advection systems will be demonstrated, using a simple two-species predator–prey system as an example model.
