An Inverse Problem for an Age-Structured Population Dynamics Model with Migration Flows
AbstractAn inverse problem of reconstructing a coefficient in the differential equation of a model of development for a homogeneous biological...

A Stage-Structured Continuous-/Discrete-Time Population Model: Persistence and Spatial Spread
Population persistence and spatial propagation and their dependence on demography and dispersal are of great importance in spatial ecology. Many...

On the Approximation of Physiologically Structured Population Model with a Three Stage-Structured Population Model in a Grazing System
ACanpwonyi, Sam Carlsson, Linus great deal of ecological theory is based on simple Lotka-Volterra-type of unstructured population models in the study... -
Measure-Valued Optimal Control for Size-Structured Population Models with Diffusion
We consider a control problem to maximize a profit from harvesting in agriculture or aquaculture, where the population is governed by size-structured...

A nonautonomous model for the interaction between a size-structured consumer and an unstructured resource
In this paper, we propose and analyze a nonautonomous model that describes the dynamics of a size-structured consumer interacting with an...

A Lipid-Structured Model of Atherosclerosis with Macrophage Proliferation
Atherosclerotic plaques are fatty deposits that form in the walls of major arteries and are one of the major causes of heart attacks and strokes....

Numerical analysis of linearly implicit Euler method for age-structured SIS model
In this paper, we consider a numerical threshold for a coupled age-structured SIS epidemic model. We deal with the existence, convergence and...

Propagation dynamics for an age-structured population model in time-space periodic habitat
How do environmental heterogeneity influence propagation dynamics of the age-structured invasive species? We investigate this problem by considering...

Threshold Dynamics for Diffusive Age-Structured Model over Unbounded Domains: Age-Dependent Death and Diffusion Rates
The global dynamics of the typical age-structured model with age-dependent mortality and diffusion rates on unbounded domains have been established....

Dynamics of a new stage-structured population model with transient and nontransient impulsive effects in a polluted environment
In this paper, we consider a new stage-structured population model with transient and nontransient impulsive effects in a polluted environment. By...

Uniqueness of the Solution of the Inverse Problem for a Model of the Dynamics of an Age-Structured Population
AbstractFor the McKendrick model of the dynamics of an age-structured population, we consider the inverse problem of reconstructing two...

A Lipid-Structured Model of Atherosclerotic Plaque Macrophages with Lipid-Dependent Kinetics
Atherosclerotic plaques are fatty growths in artery walls that cause heart attacks and strokes. Plaque formation is driven by macrophages that are...

Global stability of an age-structured population model on several temporally variable patches
We consider an age-structured density-dependent population model on several temporally variable patches. There are two key assumptions on which we...

Well-posedness and asynchronous exponential growth of an age-weight structured fish population model with nonautonomous past
We study the fish population model integrating age and weight structures, introduced in E. Sánchez, M. L. Hbid, R. Bravo de la Parra. (J. Evol. Equ....

Optimal Contraception Control Problems in a Nonlinear Size-Structured Vermin Model
This paper investigates a size-structured vermin contraception control model with nonlinear fertility and mortality, in which the control variable...

Optimal Harvesting in Age- and Size-Structured Population Models
This paper briefly surveys age- and size- structured linear and nonlinear population models and reveals their practical meaning. It focuses on... -
Efficiency of Protection in the Presence of Immigration Process for an Age-Structured Epidemiological Model
This paper studies the efficiency of protection in containing an epidemic in the case of immigration using a triple age structured model. For...

Resonance in Physiologically Structured Population Models
Ecologists have long sought to understand how the dynamics of natural populations are affected by the environmental variation those populations...

Dynamical analysis for an age-structured model of eating disorders
This paper investigates the diffusion of eating disorders by constructing an age-structured model with an age-dependent diffusion coefficient....
