Role of food conversion efficiency due to predation of prey populations in an eco-epidemiological model with Allee and refugia

Predator–prey interactions are considered to be key components in the structural framework of an ecosystem. Giving rise to rich dynamics, these engagements have always drawn attention of budding researchers. Biological processes like Allee effect have been investigated by several researchers in the field of eco-epidemiology. Regulation of chaotic dynamics under the influence of refugia cannot be neglected either. Hence, in our present investigation, we have demonstrated our model under the cumulative impact of both Allee effect and refugia. We shall also observe the role of nutritional value in regulating ailment propagation. The stability conditions for the biologically feasible equilibrium points are constructed using local stability analysis. Conditions for existence of Hopf bifurcation along with uniform persistence and global asymptotic stability have been established. Rigorous numerical investigation has been performed so as to scrutinize the impact of force of infection and nutritional value on the dynamics of the proposed eco-epidemic model.
