Abstract
    In September 1988, soil samples (0 to 0.12m) from yellow-, grey- and brown-dune sites with characteristic vegetation were taken in Jutland (south-west Denmark) to study soil micro-arthropods quantitatively and qualitatively. Although the soil type of the three sites is very similar (medium to fine sand), other soil parameters differ in a for such sites typical way. Abundances of Collembola and Acari are highest in yellow dune with 77 and 318 tsd.ind./m², respectively, followed by grey and brown dune. The deepest soil layer of 0.08 to 0.12 m was most populated in yellow dune samples. The predacious mites (Gamasina) were analyzed on species level, with 20 determined species. Species numbers in yellow, grey and brown dune are 12, 10 and 7, respectively. The Gamasina-taxocenoses of the three sites are very specific. No obvious correlations to plant species or soil parameters can be established. Hypothetical interactions with microflora and mycorrhiza are discussed.
