Структура комплекса членистоногих в гнездах европейской рыжей полевки

Abstract

Qualitative and quantitative analyses of the invertebrate fauna from nests of the common red-backed vole in the Kane reservation revealed structural organization of the nest microbiocenosis. The degree of variation in the number of invertebrates(at the level of taxonomic groups) composing the nest cenosis is characterized by dynamic equilibrium. It is manifested, on the one hand, in essential fluctuation of the seasonal abundance of invertebrates in the nests parallel with constant predominance o two groups (Gamasina and Siphnoptera), and, on the other hand, in maintaining a relative constancy of the quota of most invertebrates in the total nidicolous complex in all seasons of the year. Trophic structure of the nidicolous complex is also characterizedby a definite order in the quantitative relation of trophic groups. Seasonal variations within the order are insignificant.
