Modelling dynamics of the limited population with age and sex structure

We investigate the three-componental model of population number dynamics characterized a regular reproduction season. In this model we account for a population sex and age structure and density dependent effects acting on survival rate of a younger age class. We consider particular cases of the model depending on whether various correlation of population parameters. We research transition scenarios from the stability to cyclic and irregular modes of number dynamics. We formulate informative conclusions about sex structure role for processes of population dynamics and self-organizing.
