Dispersal between Two Patches in a Discrete Time SEIS Model

Dispersal and dormancy are two of the fundamental evolutionary mechanisms used by nature to support and generate ecological diversity. In this investigation, we focus on the role of disease-enhanced or disease-suppressed dispersal on the dynamics of populations in a multi-patch system. Single patch systems, which are capable of supporting simple and complex dynamics, are studied both analytically and numerically. The impact of disease and dispersal is also studied numerically. Our results are compared to those in the literature that focused on dispersal in disease free multi-patch systems.
