Abstract

Emergence of Spatial Patterns in a Simple Model of Wetland Ecosystem: Application to Keoladeo National Park (KNP), India

An attempt has been made to understand the spatiotemporal dynamics of good biomass, bad biomass and bird population in the wetland part of KNP. Spatiotemporal distributions of species biomass are simulated using the diffusivity assumptions realistic for natural wetland systems. Stability analysis, Hopf-bifurcation and diffusion-induced instability of the model system have been carried out. Computer simulations performed to identify various parameters for the good health of the wetland ecosystem. We observed that growth rate and carrying capacity for the bad biomass, carrying capacity and half-saturation constant of the good biomass are responsible for the good health of the wetland ecosystem. The spatial movements of good biomass acquires stable stationary patterns in the presence of bad biomass which performs swinging motion and selects a steady state spatial pattern, thereby ensuring the persistence as well as extinction of multiple species system in space and time.
