abstract
The seasonal changes in the quantitative development of ciliates pedobionts in forest and cultivated soils of Samur-Yalama National Park have been investigated. Long-term observation of the quantitative development of the free-living ciliates of soil communities in different areas of the Samur-Yalama National Park showed that, occasionally two distinct maximum number of development and biomass of ciliates pedobionts attributable to the spring and autumn seasons are observed at fixed points located at a distance from settlements. It was found that species diversity of soil ciliates considerably had reduced in the places of strong anthropogenic influence and the main development accounts for a small number of species eurybionts, occasionally developing a large number.
