Self-segregation of competitive chaotic populations

The dynamical behavior of species competing for a common resource is studie d with a reaction-diffusion system based on cubic autocatalysis. Randomly s eeded populations self-segregate to from a complex network of domains separ ated by distinct interfaces. For chaotic populations in one-dimensional med ia, the interfaces exhibit irregular motions on long time scales. In two-di mensional media. the interface motions are governed by curvature-induced dr ift.
