[Cyclic changes in the population count of the taiga tick in the Stolby preserve].

A harmonic analysis was carried out of Ixodes persulcatus density dynamics over 33 years and the analysis of small mammal density and some climatic factors. It was found that the chronological changes of all the three processes contained cyclic components with the period 5.5 and 11; 3-4; 5.5 and 14-16 years, respectively. A long-term prognosis of I. persulcatus density was made based on harmonic synthesis.
