Анализ стохастической возбудимости в модели популяционной динамики

Abstract

This paper discusses Bazykin population model with intraspecific competition of each population and predator saturation factors. The parametric zones of mono- and multistability are analyzed. For the case of environmental impact, described by parametric noise, transitions of random trajectories between basins of attraction are studied. The phenomena of stochastic excitability and generation of stochastic oscillations of mixed modes are described by the confidence domain method.
