The study revealed that each population level of animals corresponded to a specific morphophysiological type. Significant differences were revealed between the values of several energy and immune parameters at high and low population levels. In the phase of "peak" number the level of most physiological indicators were consistent with stressful. The participation of stress is assumed in the suppression of reproduction and increased mortality of voles observed in the phases of high numbers. ER -
