Switching Feeding Among Sound and Infected Prey in Ecoepidemic Systems

Abstract

We investigate the switching feeding behavior of predators in the context of one single prey population, which is disease affected. We consider the case of hunting indiscriminately both types of prey, when the infected prey causes no harm to their predators, but assume also in another model that feeding on the infected individuals has a negative return on the predators. Some counterintuitive results are obtained and discussed.

Ecoepidemiology: a More Comprehensive View of Population Interactions

“…In E. Venturino Ecoepidemiology [81] one such model is presented in the context of ecoepidemiology. In contrast to purely demographic models, in which the feeding switching occurs among two different prey populations, see e.g.…”

Chaos control via feeding switching in intraguild predation systems

“…Even establishing the existence of the equilibrium amounts to solve a highly nonlinear algebraic system. An attempt along these lines has been made in [9], see also [8], but will not be repeated here. Rather, numerical simulations show the feasibility and stability of this point, Fig.…”

Stability and global dynamic of a stage-structured predator–prey model with group defense mechanism of the prey

“…This is an interesting fact because only the mature class is preyed. When the selective predation is on the most abundant prey, the phenomenon is known as switching and has been considered in many papers, see for example, [14,16,17,19,21,22,26], and in a different context [1,[3][4][5]28]. Another important aspect that could be present in a predator-prey relationship is the ability of the prey to better defend themselves when their number is large.…”
