Аннотация:The study discusses the aspects of the seasonal dynamics of soil macrofauna in the forest ecosys
tems of the PriokskoTerrasny State Nature Biosphere Reserve. The diversity of the group composition, total indices of biomass, and number of individuals are shown to grow from spring to autumn, while the dominant groups and structural characteristics remain unchanged. The composition of dominants and eudominants persists despite the abrupt changes in the number of individuals within the complexes.
