Complex modes of population number dynamics with age and sex structures

Efim Frisman, Oksana Revutskaya, Galina Neverova

In this paper we research a three-component mathematical model of population number dynamics. It considers sex and age structure dynamics and density-dependent effects impact on survival rates of a younger age class. We investigate some scenarios of the stabilized number transition to nonlinear modes of dynamics dependent on system parameters values and the type of the survival function. The results of numerical simulations are discussed.
