Soil nematodes in five spruce forests of the Beskydy mountains, Czech Republic

Sununary Soil nematode communities were studied in five 5 to 138 year-old spruce forests in the Beskydy Mountains, Northern Moravia, Czech Republic. A total of 92 species was found in ail stands studied. Nematode abundance ranged from 272.9 to 6238.9 x 103 ind·m-z (mean value 1409.6 x 103 ind·m-Z), biomass varied from 33.6 mg·m-z to 1.197 mg·m-z (mean value 337.2 mg·m-Z). Myco-phyrophagous nematodes of the order Tylenchida had the grearest abundance but individual genera differed in their preference for the spruce forests studied. The abundance of bacreriophagous nematodes was similar in alllocalities. The composition of nematode communities was influenced by the age of spruce trees, herbaceous undergrowth and altitude.
