Abstract:

In four types of beech wood Fagetum carpaticum in the Bieszczady National Park: dry and poor F. c. festucetosum drymejae, fresh F. c. typicum, moist F. c. lunarietosum, and F. c. variant with Alium ursinum, 13 species of earthworms were found. These are - Dendrobaena alpina, D. octaedra, Allolobophora cernosvitoviana, A. rosea, A. caliginosa, A. carpathica, Fitzingeria platyura montana, Lumbricus terrestris, L. rubellus, Octolasion lacteum, Octodrilus transpadanus, Dendrodrilus rubidus tenuis, and Eisenia lucens. In order to determine the species diversity, the S’/S test was used. Some biocenosis indicators: dominance, frequency and association were considered as well. Of 13 species only D. alpina, A. cemosvitoviana and A. carpathica, present at all sites, occurred in large numbers.
