|
| Authors: | Jiang Liqing Ma Zhien |
| Abstract: | A predator-prey system in a polluted environment is studied in this paper.Surveying the transformation of toxicants from prey to predator and the effects of toxicants on functional response of predator comprehensively, the thresholds between the weak persistence in the mean and extinction of populations are established. |
| Keywords: | population toxicant weak persistence in the mean extinction threshold |
