Abstract

OXYGEN CONSUMPTION BY SOIL-INHABITING NEMATODES BY R. Z. KLEKOWSKI,* L. WASILEWSKA,** and E. PAPLINSKA** Oxygen consumption by 22 species of soil-inhabiting nematodes was measured using the cartesian diver method. The exponent of regression for respiration-weight dependence was 0.67 indicating that respiration intensity is proportional to the surface area of the body of those nematodes examined. A comparison was given of respiratory rate (R) and metabolic rate (MR) in various trophic groups of nematodes. Comparisons of the oxygen consumption of nematodes measured by other authors indicated a considerable resemblance in the type of energy meta- bolism of the whole group of nematodes, irrespective of their habitats. The respiration equations calculated by the authors : R = (1.40 ± 1.17) W0.72 ± 0.092; (MR = 1.40 x W-0.28) can be used to assess the requirements needed to maintain nematode communities, if their abundance and age distribution are known. The estimation of oxygen consumption by nematodes can be utilized in studies on the productivity of these animals in different ecosystems. Taking into account rather large differences in size of nematode species as well as their different way of life, considerable differences in the oxygen consumption might be expected. Only a few
