| Abstract: | A two species discrete non-autonomous competitive phytoplankton system with nonlinear inter-inhibition terms and toxin producing species is studied in this paper. By constructing some suitable Lyapunov type extinction functions, sufficient conditions which guarantee the extinction of a species and the global attractivity of the other one are obtained. Our results supplement the conclusion in the literature 2] and 11]. |
