Abstract
The aim of our study was to reveal patterns of soil macrofauna abundance variation during vegetation season. The studies were carried out in Russia, Volga-Kama reserve. The latter is divided into two part – Raifa (55.900330, 48.723119) and Saraly (55.308186, 49.239262). We sampled macrofauna their in 4 biotopes. Additionally buffer zone was investigated: 2 biotopes under anthropogenic impact. In each biotope, the spring and autumn abundance was estimated for three years. In the Saralinskii section of the reserve, in most cases, it differed insignificantly. In the Raifa section earthworms abundance declined toward autumn slightly. In buffer zone, there was a tendency to decrease in abundance by autumn, which, apparently, is associated with anthropogenic influence.
