In this paper we investigate long-term dynamics of the most basic model for stage-structured populations, in which the per capita transition from the juvenile into the adult class is density dependent. The model is represented by an autonomous system of two nonlinear differential equations with four parameters for a single population. We find that the interaction of intra-adult competition and intra-juvenile competition gives rise to multiple attractors, one of which can be oscillatory. A… 
Global Bifurcation Analysis of a Population Model with Stage Structure and Beverton-Holt Saturation Function
A complete bifurcation analysis of a two-stage population model, in which the per capita birth rate and stage transition rate from juveniles to adults are density dependent and take the general Beverton–Holt functions, is performed.
Multiparametric bifurcations of an epidemiological model with strong Allee effect
The rich and complicated dynamics exhibit that the model is very sensitive to parameter perturbations, which has important implications for disease control of endangered species.
The saddle-node-transcritical bifurcation in a population model with constant rate harvesting
We study the interaction of saddle-node and transcritical bifurcations in a Lotka-Volterra model with a constant term representing harvesting or migration. Because some of the equilibria of the model
Qualitative Analysis of a Prey-Predator Model with Stage Structure for the Predator
It is found that a Hopf bifurcation occurs in the ODE system, but no Turing pattern happens in the reaction-diffusion system; however, when a natural cross diffusion term is included in the model, it can prove the emergence of stationary patterns for this system.
Codimension-1 Sliding Bifurcations of a Filippov Pest Growth Model with Threshold Policy
A Filippov system is proposed to describe the stage structured nonsmooth pest growth with threshold policy control, which exhibits the interesting global sliding bifurcations sequentially and implies that control outcomes are sensitive to the threshold level, and hence it is crucial to choose the thresholdlevel to initiate control strategy.
Dynamical Systems with a Codimension-One Invariant Manifold: The Unfoldings and Its Bifurcations
A dynamical system having a special structure namely a codimension-one invariant manifold that is preserved under the variation of parameters is investigated, and conditions such that bifurcations of codimensions-one and of codIMension-two occur in the system are derived.
Complex Dynamics of a Filippov Three-Species Food Chain Model
It is demonstrated that the threshold policy control can be easily implemented and used for stabilizing the chaotic behavior of FFCM, which has stable periodic, double periodic and chaotic solutions as well as double periodic sliding bifurcation.
Bifurcation of Codimension 3 in a Predator-Prey System of Leslie Type with Simplified Holling Type IV Functional Response
It is shown that for the same model there exists a unique degenerate positive equilibrium which is a degenerate Bogdanov–Takens singularity (focus case) of codimension 3 for other values of parameters.
Threshold Strategy for Nonsmooth Filippov Stage-Structured Pest Growth Models
In order to control pests and eventually maintain the number of pests below the economic threshold, in this paper, based on the nonsmooth dynamical system, a two-stage-structured pest control
Sliding Bifurcations of Filippov Two Stage Pest Control Models with Economic Thresholds
It is shown that interadult competition alone can give rise to multiple sliding segments and multiple pseudoequilibria, whilst interadult and interjuvenile competition together can result in rich sliding bifurcations.

Codimension Two bifurcations in a predator-prey System with Group Defense
In this paper we study the qualitative behavior of a predator–prey system with nonmonotonic functional response. The system undergoes a series of bifurcations including the saddle-node bifurcation,
On the formulation and analysis of general deterministic structured population models I. Linear Theory
A linear physiologically structured population model by two rules, one for reproduction and one for “movement” and survival is defined, and unbounded operators are avoided throughout to facilitate the treatment of nonlinear models as a next step.
A numerical procedure is presented for the automatic accurate location of certain codimension-two homoclinic singularities along curves of codimension-one homoclinic bifurcations to hyperbolic
