Interactions between soil microorganisms and invertebrates in the course of the transformation of plant residues in soils of northern Fennoscandia.

摘要

The intensity of the decomposition of plant residues and changes in the trophic and taxonomic structure of communities of microorganisms and invertebrates (Acari, Collembola, Enchytraeidae, Diptera) taking part in this process were studied in natural podzolic soils of northern Fennoscandia. There was a relatively weak dependence of the intensity of plant residues on the genetic properties of the soils and the soil pollution by heavy metals. A new trend of strengthening of the trophic interrelations between the invertebrates and microscopic fungi in polluted soils (as compared to "clean" soils) was found. Data are presented.
