Threshold parameters and metapopulation persistence.
A method is presented to estimate the minimum viable metapopulation size based on the basic reproductive number R(0) and the expected time to extinction tau(E) for 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.
