Dynamic behavior of a plant-wrack model with spatial diffusion

Banded spatial pattern of plant is one of the center issues in the real ecosystems. As a result, in this paper, a plant-wrack model with spatial diffusion is presented. By both mathematical analysis and numerical simulations, we find that the typical dynamics of plant is the formation of isolated groups. i.e., Spotted, labyrinth, and coexistence of stripe-like and spotted. The obtained results may provide help in Understanding the dynamics in the real ecosystems. (C) 2009 Elsevier, B.V. All rights reserved.
