Uniform persistence and permanence for non-autonomous semiflows in population biology
The author proves that under certain additional conditions uniform weak persistence implies uniform strong persistence. Then he shows how persistence theory can be turned around to demonstrate ultimate boundedness (or point dissipativity) for non-autonomous semiflows. Finally, these results are applied to establish threshold criteria for disease extinction and disease persistence in time heterogeneous SIRS epidemic models and to establish permanence for a one species model consisting of a scalar retarded functional-differential equation.
