Research Article Global Behavior for a Diffusive Predator-Prey Model with Stage Structure and Nonlinear Density

A Holling type III predator-prey model with self- and cross-population pressure is considered. Using the energy estimate and Gagliardo-Nirenberg-type inequalities, the existence and uniform boundedness of global solutions to the model are dicussed. In addition, global asymptotic stability of the positive equilibrium point for the model is proved by Lyapunov function. Copyright q 2009 Rui Zhang et al.
