Dynamics of a spatiotemporal model on populations in a polluted river

In this paper, we investigate the dynamics for a reaction-diffusion-advection system which models populations in a polluted river. More precisely, we study the stability of steady states, which yields sufficient conditions that lead to population persistence or extinction. Furthermore, some dependence of the stability of the toxicant-only steady state and the population-toxicant coexistence steady state on the model parameters are given.(c) 2022 Elsevier Ltd.

Automated summary

In this paper, the dynamics of a reaction-diffusion-advection system modeling populations in a polluted river are investigated. The stability of steady states is specifically studied, providing sufficient conditions for population persistence or extinction. Additionally, the dependence of the stability of the toxicant-only steady state and the population-toxicant coexistence steady state on the model parameters is given.
