Predator-Prey model with Holling response function of type II and SIS infectious disease

Abstract

We analyze the influence of a SIS infectious disease affecting Preys or both Predators and Preys in a Predator-Prey model. The response function used here is Holling function type II. Many thresholds are computed and used to investigate the global stability results. The disease can disappear from the community, persist in one or two populations of the community. At least one population can disappear from the community because of disease. In some cases, the model exhibits periodic solutions with persistence of the disease or without disease. Numerical simulations are used with nonstandard numerical schemes to illustrate our results. © 2012 Elsevier Inc.
