Dynamical behavior of a stage structured prey-predator model
In this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. The stages for prey have been considered. The proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. The model is analyzed by using linear stability analysis to ob...
متن کاملHopf Bifurcation in Predator-prey Models with an Age Structured Prey
In this paper is analyzed the existence of periodic orbits in a predator-prey interaction, when the predator feeds on each one of the two age classes of prey. Three families of models are considered in correspondence with different prey and predator behaviors. Specifically, a constant predation rate on the non reproductive class of the prey is considered in the first family; a Holling predation...
متن کاملA Stage-structured Predator-prey Model
This chapter, originally intended for inclusion in [4], focuses on modeling issues by way of an example of a predator-prey model where the predator has a juvenile stage. A careful derivation of the model is given starting from an age-structured model for the predator population. The method of characteristics is used to reduce the partial differential equations to a system of integro-differentia...
متن کاملSpatial stochastic predator-prey models
We consider a broad class of stochastic lattice predator-prey models, whose main features are overviewed. In particular, this article aims at drawing a picture of the influence of spatial fluctuations, which are not accounted for by the deterministic rate equations, on the properties of the stochastic models. Here, we outline the robust scenario obeyed by most of the lattice predator-prey model...
