"Soil fauna plays an active role in ecosystem succession. It decomposes mechanically dead organic matter in soil, produces characteristic soil microstructures and contributes to humus form development. Many of the succession mechanisms in soil are poorly known. The studied primary succession takes place on 35, 45 and 80 years old deposits of a chemical factory at Petrovice u Karvin\u00E9. Only some groups of soil animals entered less developed succession stages of chemically extreme deposits. This will allow to distinguish better their role in soil formation processes in absence of same groups of soil fauna. Soil meso- (Collembola, Oribatida) and microfauna (Testacea, Nematoda) communities will be studied in the mentioned succession stages and compared with adjancent climax communities. The role of animals in soil microstructure and humus form development will be studied and quantified on soil thin sections."@en . "1"^^ . . .
