Abstract

We investigate a reaction-diffusion-advection system describing the interaction between a population and a toxicant in open advective environments. The interesting feature of this model is the consideration of a more general advective term and boundary condition. By applying the theory of monotone semi-flow and principal eigenvalue, we obtain the existence and stability of steady states and further present a clear picture on the local and global dynamics. We explore the effects of toxicants on populations and give some sufficient conditions for the existence or extinction of the population.
