In the recent past the author has investigated models of infectious diseases spreading in one of two species constituting an ecosystem. In this paper we again investigate the effects of an epidemic which spreads in a system of two interacting populations, but remove a simplifying assumption and allow the disease to affect both species. The equilibria of the system are computed analytically and their stability is determined. These calculations provide an answer to some ecological questions that may be raised in managing the environment.

Abstract
In the recent past the author has investigated models of infectious diseases spreading in one of two species constituting an ecosystem. In this paper we again investigate the effects of an epidemic which spreads in a system of two interacting populations, but remove a simplifying assumption and allow the disease to affect both species. The equilibria of the system are computed analytically and their stability is determined. These calculations provide an answer to some ecological questions that may be raised in managing the environment.File in questo prodotto:
