Persistence and extinction of a population in a polluted environment
The authors investigate models of the persistence and extinction of a population in a polluted environment. They don't make the unnatural assumption that the capacity of the environment is so large that the change of toxicant in the environment that comes from uptake and egestion by the organism can be neglected. The main results are some sufficient conditions on persistence or extinction. Additionally, the threshold between the two has been obtained for most situations of interest.
