Stochastic sensitivity of limit cycles for «predator – two preys» model

We consider the population dynamics model «predator – two preys». A deterministic stability of limit cycles of this three­dimensional model in a period doubling bifurcations zone at the transition from an order to chaos is investigated. Stochastic sensitivity of cycles for additive and parametrical random disturbances is analyzed with the help of stochastic sensitivity function technique. Thin effects of stochastic influences are demonstrated. Growth of stochastic sensitivity of cycles for period doubling under transition from order to chaos is shown.
