Variability of long-term cyclicity in the population dynamics of the northern red-backed vole (Myodes rutilus (Pallas, 1779))

In the article we consider the ranges of periodic components of the long-term population dynamics of the northern red-backed vole in different parts of the area. We found that the harmonic components of the spectra constructed for different regions coincide in most frequency bands. The differences in geographic populations are manifested only in the ratio of the power of the same harmonics. Specific features of the population cyclicity in the northern and southern populations are revealed. It is assumed that the populations of the northern red-backed vole adjust their rhythms to the outer cycles.
