The sites in question were spruce (Picea abies) forest with clear or else relatively limited signs of degradation, with the intensity of this phenomenon being determined in relation to the incidence of treefall, young spruce stands, and grass-herb communities. lntensified degradation was found to reduce the diversity and maturity of nematode communities and to increase the numerical representation of fungivorous species. Dry conditions intensified these changes. The nematode communities of the aforementioned mountainous areas contaminated by acid rain were then compared with those studied by author about 20 years previously in other parts of Poland and considered uncontaminated. Communities from the contaminated areas were not found to have lower total numbers of nematodes, but did differ in the higher representation of fungivores and obligate plant parasites as well as in the absence of predators. A shift in the direction of feeding on fungi was noted among species feeding on reducers. Aspects unique to these communities which were noted on the scale of trophic differentiation were the loss of characteristic K-strategists (specially predators), and also loss of bacterivorous r-strategists in favour of more K-strategic bacterivores.}, title={The influence of acid rain on soil nematode communities: a comparison of contaminated habitats in the belt of the Karkonosze and Izerskie Mountains (South-West Poland) with uncontaminated areas in other regions of Poland}, type={Text}, URL={http://rcin.org.pl/miiz/Content/86877/PDF/WA058_89656_P2840-T44_Eko-Pol-A-Nr-1-2.pdf}, volume={44}, number={1-2}, journal={Ekologia Polska}, publisher={Oficyna Wydawnicza Instytutu Ekologii PAN}, keywords={acid rain, soil nematodes, taxonomic composition, trophic groups, diversity index, maturity indices}, }
