A total of 90 species were identified. 69 of which occurred in the Rokytská Slať and 66 in the Chalupská Slať. The majority of these nematodes belonged to the orders Dorylaimida (32%, mostly omnivorous Eudorylaimus), Araeolaimida (25%, mostly bacterivorous Plectus) and Tylenchida (20%, mostly root-fungal feeders Filenchus). Multivariate analyses revealed that the composition of nematode assemblages was more influenced by local conditions in individual patches of peaty soil than by the peat bog as a whole. Nevertheless, a certain effect of the peat bog on the nature of the nematode faunas was detected. Abundant populations of Jensenonchus sphagni indicated top-down control of nematode assemblages in the ombrotrophic Rokytská Slať peat bog. High values of the sumaMI and MI indices and low values of the PPI/MI ratio generally indicated that the peat bogs studied were in terms of habitats for free-living nematodes undisturbed or only slightly disturbed. Peat bogs thus can play an important role in the preservation of nematode diversity in the Šumava Mts. A significant change in the composition of the nematode assemblages can be used an indicator of the degradation of the peat bogs in the Šumava Mts.
