This paper addresses the bifurcation control of a fractional-order Lokta-Volterra predator-prey model by using delay feedback control. By employing time as parameter, conditions are gained for controlled systems. Then, it indications that onset can be postponed gain decreases. An example numerical results ultimately exploited to validate correctness proposed scheme.

For over a hundred years, the model of prey–predator has been handled extensively. It proved that Lotka–Volterra (LV) models are not stable from all previous studies. In these models, there is divergent extinction one species or cyclic oscillation. There no solution for asymptotic stability models. this paper, Caputo fractional-order prey-two predators’ with an immigration effect investigated. ...

Abstract In this paper, we consider a new fractional-order predator–prey model with Holling type-III functional response and stage structure. Based on the Lyapunov stability theory by constructing suitable functional, obtain some sufficient conditions for existence uniqueness of positive solutions asymptotic equilibrium to system. Finally, give numerical examples illustrate feasibility our resu...

Seasonal changes in the diel feeding patterns of the zooplanktivorous icefish (Neosalanx taihuensis), which is an endemic species of China, were studied in the large, shallow eutrophic Lake Chaohu of China during the autumn of 2002 and summer of 2003. The results of the diel feeding rhythm indicate that icefish is a visual particulate feeder. There were large differences in diet composition and...

An eco-epidemiological model involving competition regarding the predator and quarantine on infected prey is studied. The divided into three compartments, namely susceptible, infected, prey, while only attacks due to its weak condition caused by disease. To include memory effect, Caputo fractional derivative employed. validated showing existence, uniqueness, non-negativity, boundedness of solut...

In this work, a discretization process of fractional-order prey and predator model is discussed. The aim work to describe the population phenomenon which contains predator. research, by Ghosh et al. (2017) used. has an unique form because it refuge additional food order give more details on population, then modified into fractional discretized. three points equilibrium one them named co-existin...
