COMPARATIVE ANALYSIS OF DIFFERENT TYPES OF DENSITY REGULATION OF BIRTH RATE AFFECTING POPULATION CHANGES OF STRUCTURED POPULATIONS

Dynamics of number of the structured limited population with seasonal reproduction has been investigated in the article and taken as a model here. We compare the dynamic regimes having density regulation of birth rate and survivability of the young. It is shown that autoregulation of growth may cause periodic oscillations and a change of the dynamic regime.

Keywords: mathematical model, population, age structure, density-dependent regulation, dynamic regimes, basins of attraction
