A field experiment was designed to estimate the effect of soil surface patrolling by macroarthropods on organic matter content in soil. One of the components of this experiment was the soil nematode community - density, trophic and dominance strukture, the diversity and maturity indices. These parameters were compared between two types of mesocosms: accessible and inaccessible to macroarthropods. The experiment was performed under natural environmental conditions and did not reduce the diversity of the biota characteristic of the ecosystem. Most parameters of nematodes did not vary significantly between mesocosms. Differences between mesocosms observed over the 5-month period of each of the two experiments (1992 and 1993) concerned mainly, bacterivorous nematodes and, within this trophic group, colonizers. The densities of the taxon Rhabditis s.l. were statistically higher in the mesocosms accessible to macroarthropods, and the proportion of colonizers (r-strategists s.l.) among bacterivorous nematodes was also higher.
