The threshold of population survival in a polluted chemostat model

The influence of toxicants on n competitive populations in an unsimplified chemostat model is investigated, where the nutrient input and washout rate are allowed to be time variable. The threshold between persistence and extinction of the populations has been obtained for sufficiently small initial...

More Information
Summary:The influence of toxicants on n competitive populations in an unsimplified chemostat model is investigated, where the nutrient input and washout rate are allowed to be time variable. The threshold between persistence and extinction of the populations has been obtained for sufficiently small initial densities.
