Abstract: 
Collembola from a German beech wood soil on limestone were sampled using corers of 2 different sizes, pitfall-traps, an arboreal photoelector and an aspirator. From Dec. 1979-Nov. 1980 the population density fluctuated from 22,000-55,000 individuals/m2 (average density: 37,000 ind. [individuals] .cntdot. m-2). Within the research area, 44 spp. were found. The most abundant species were Isotomiella minor > Tullbergia krausbaueri > Folsomia quadrioculata. The biomass varied from 100-230 mg dry weight m-2. T. flavescens and Lepidocyrtus lignorum were the species with the highest average dry weight. Generally 60% of the individuals of the collembolan fauna were found in the uppermost 3 cm of the soil. Only F. quadrioculata showed a close correlation between vertical distribution and temperature. The analysis of the distribution pattern of this species lead to the conclusion that the spring and the fall generation behave differently depending on change in climate and resource. Goodness-of-fit tests show that the negative binomial distribution defined the distribution of the sufficiently sampled species very well. For none of the springtail species a common k [dispersal index] could be established. According to the Morisita index of dispersion Hypogastrura denticulata had the most, Megalothorax minimus the least significant deviations from random distribution. Some species were closely restricted to microhabitats. T. callipygos preferred areas, where the forest floor is covered by Anemone nemorosa. This is possibly due to the lower pH-values of these areas. The surface structure and the herbaceous layer have an important influence on the mobility of certain collembolan species. H. denticulata showed the highest activity. Some species occurred in high numbers in an arboreal photoelector 2 m above ground level. Most of the typical arboreal species prefer parts of the trunks with a thick layer of epiphytic algae. Near the trees the density of T. flavescens and Entomobrya muscorum increased during the summer months. By means of size class analysis an estimation of hatching periods and the numbers of generations was possible. Sminthurus viridis, Dicyrtomina ornata and Bourletiella bincincta seem to be in a state of egg diapause during part of the year.
