Species and genera of soil nematodes inhabiting tree plantations on colliery spoils near Sokolov
Háněl, Ladislav
Soil nematodes were studied in 20-30-year-old tree plantations and spontaneous successions on colliery spoils near Sokolov in west Bohemia, Czech Republic. Six types of tree plantations (oak, alder, linden, larch, pine, and spruce) and one type of spontaneous succession (willow-aspen-birch), each in four replicate sites, were surveyed in March 2005 and in April 2006. In total 174 species and 86 genera were distinguished, more species and genera were found in deciduous than in coniferous plantations. Cluster analyses showed different composition of nematode faunas in those plantations. Co-occurrence of closely related .i.Aporcelaimellus, Helicotylenchus./i. species could suggest their still existing niche overlap in a developing environment whereas niche partitioning probably established between species of the genera .i.Eudorylaimus./i. and .i.Paratylenchus./i..
