Double-parameter bifurcation of a predator-prey system in advective environments

This paper is concerned with a diffusive predator-prey system incorporating a generalist predator in open advective environments. By simultaneously considering the advection rates of the predator and prey as bifurcation parameter, we apply the implicit function theorem to establish the existence of...

Zusammenfassung:This paper is concerned with a diffusive predator-prey system incorporating a generalist predator in open advective environments. By simultaneously considering the advection rates of the predator and prey as bifurcation parameter, we apply the implicit function theorem to establish the existence of positive steady state of this system. Furthermore, we demonstrate that the positive steady state is locally asymptotically stable. These findings not only enrich the theoretical research on predator-prey models but also offer novel perspectives and methodologies for studying population dynamics in riverine ecosystems.
