Dynamics of infectious diseases in predator–prey populations: A stochastic model, sustainability, and invariant measure

Abstract

This paper introduces an innovative model for infectious diseases in predator–prey populations. We not only prove the existence of global non-negative solutions but also establish essential criteria for the system’s decline and sustainability. Furthermore, we demonstrate the presence of a Borel invariant measure, adding a new dimension to our understanding of the system. To illustrate the practical implications of our findings, we present numerical results. With our model’s comprehensive approach, we aim to provide valuable insights into the dynamics of infectious diseases and their impact on predator–prey populations.
