“…Another popular explanation is that the stochastic forces are ubiquitous and when they are accounted in mathematical models, then the instability of E 0 may be lost. A more recent and intriguing explanation is that in the limiting scenarios when searching time is very small (like in a small island, or fragmented small patches), our functional responses can be approximated by the so-called ratio-dependent functional responses [10,14,15]. For such functionals, the origin can indeed be an attractor.…”

“…The model can take various forms depending on the specific choices of infection mechanisms and the predator functional responses. Appropriately formulated, these models shall be able to generate rich extinction dynamics such as the one documented in Hsu et al (2002). An example of such models with prey-dependent functional response may take the form Here x is the resource that interacts with pest.…”

“…There are several researchers (cf. [9,11,13,15,16,17,22,24]) who have concerned about the ecological systems with three and more species like system (1.2) to understand complex dynamical behaviors of ecological systems in the real world. Especially, the authors in [17] proposed a prey-predator model with two-type functional response and impulsive biological control by adding impulsive biological control strategy to the above system and investigated the existence of an asymptotically stable prey-free periodic solution under some conditions and established the permanence conditions for the impulsive system.…”
