This article studies nonlinear n-resource-consumer autonomous system with age-structured consumer population. The model of consumer population dynamics is described by a delayed transport equation, and the dynamics of resource patches are described b

In this article we study a nonlinear age-structured consumer population model with density-dependent death and fertility rates, and time delays that model incubation/gestation period. Density dependence we consider combines both positive effects at l

We use the analytical approach and numerical modeling to analyze the dynamics of the population of biological cells based on the polycyclic age-structured model. We reduce the initial---boundary-value problem for transport equation to the Volterra in
