Zusammenfassung:A method is presented to estimate the minimum viable metapopulation size based on theCopyright basic reproductive numberR0and the expected time to extinction τEfor epidemiological models. We exemplify our approach with two simple deterministic metapopulation models of the patch occupancy type and then proceed to stochastic versions that permit the estimation of the minimum viable metapopulation size.
