Patterns in the wake of invasion

Spatial distributions of ecological species are usually distinctly heterogeneous, but the main processes underlying these heterogeneities, as well as scenarios of ecological pattern formation, are often rather poorly understood. A conceptual model treating ecological patterns as the diffusion-induced “dissipative structures” in a system of interacting ecological species, such as a predator and its prey, was considered in the previous chapter. This approach, however, was shown to have severe limitations and, apart from a few specific cases, pattern formation due to a Turing-type diffusive instability can hardly be regarded as a common scenario.
