Abstract: The dependence of total population and population distribution on the spatial distribution of the intrinsic growth factor is studied. The existence of solutions of a nonlinear single species and the corresponding predator-prey model is established. The solutions are then approximated by the Galerkin finite element method. Simulations are performed to show, for instance, how (under the Dirichlet boundary condition) a more favorable distribution of growth factor for the prey in a predator-free situation may well be less favourable than another distribution under the pressure of the predator.
