Modeling of alternate stable states in ecological systems

Speaker : Dr. Sarath Sasi


Abstract :

We look at a reaction-diffusion model used to describe the steady states of a logistically growing population with the added effect of herbivore grazing. The ecosystem is assumed to be spatially homogeneous. It also describes the dynamics of the fish population with natural predation. In this talk we discuss the existence of multiple positive solutions leading to the occurrence of an S-shaped bifurcation curve.
