STRANGE ATTRACTORS IN SIMPLEST MODELS OF THE BIOLOGICAL POPULATIONS NUMBER DYNAMICS

Oksana Zhdanova, Efim Frisman
Our work is devoted to the theoretical analysis and discussing of the nature of biological populations’ number fluctuations by the examples of simplest mathematical models, which consider the density dependent limitation of the population number. The model for population with two age classes has been analyzed in our work. We have shown that presence of density depended ecological factors is capable to result in highly complicated behavior of population number, on condition that population number changes discretely in fixed breeding seasons.
