Omnivory and food web dynamics
Intraguild predation is a trophic interaction in which two consumers compete for one resource and where one of the consumer species may also feed on its competitor. The intraguild predator’s diet follows from the relative strength of its interactions with its potential prey. Current view holds that weak interactions between species promote the stability of food webs. To the contrary, nutrient e...
متن کاملDiscretization of a fractional order ratio-dependent functional response predator-prey model, bifurcation and chaos
This paper deals with a ratio-dependent functional response predator-prey model with a fractional order derivative. The ratio-dependent models are very interesting, since they expose neither the paradox of enrichment nor the biological control paradox. We study the local stability of equilibria of the original system and its discretized counterpart. We show that the discretized system, which is...
متن کاملComplex dynamics of a three species food-chain model with Holling type IV functional response
Abstract. In this paper, dynamical complexities of a three species food chain model with Holling type IV predator response is investigated analytically as well as numerically. The local and global stability analysis is carried out. The persistence criterion of the food chain model is obtained. Numerical bifurcation analysis reveals the chaotic behavior in a narrow region of the bifurcation para...

متن کاملGlobal Stability and Persistence of Three Species Food Web Involving Omnivory
In this paper, the dynamics of a three species food web model consisting of producers, primary consumers and omnivory is studied analytically as well as numeri-cally. The existence of equilibrium points and local stability analysis for this model is carried out together with a bifurcation analysis. The occurrence of hopf bifurcation is also investigated. The persistence conditions of the food w...
