Abstract: Soil nematodes were studied in ten forest habitats in the Voděradské bučiny National Nature Reserve in the Czech Republic. A total of 108 species of nematodes were found. The total mean abundance of nematodes was 1665 x 103 ind.m-2 and the abundance recorded on different dates varied from 339 to 4282×103 ind.m-2. Most of the nematodes belonged to the trophic groups: root-fungal feeders (44%, mainly Filenchus accompanied by Malenchus), bacterivores (25%, mainly Plectus and Acrobeloides) and fungivores (19%, Aphelenchoides). The mean biomass of nematode assemblages was 229 mg.m-2 and on the different dates varied from 31 to 813 mg.m-2. The most diverse and mature nematode fauna was recorded in an herbaceous plant-rich alder-beech forest near a small stream where the soil was well supplied with water and soil pH and carbon content were the highest of all the localities studied. |
