Title: Persistence in a Discrete-time, Stage-structured Epidemic Model


Abstract: Discrete-time SI and SIR epidemic models, formulated by Emmert and Allen, for the spread of a fungal disease in a structured amphibian host population, are analyzed. Criteria for persistence of the population as well as for persistence of the disease are established. Global stability results for host extinction and for the disease-free equilibrium are presented.
