Abstract: 

The larvae of the elaterid beetle Athous subfuscus served as an example of the effect of
humiphagous arthropods on the nutrient turnover of the decomposer microorganisms in three
contrasting beech forest soils(rnull, moder and lirned rnoder). The larvae reduced the microbial
immobilization of nutrients as N, P, K and Ca by reducing the size of the microbial biomass. In
the moder soil, A. subfuscus increased the nutrient requirements of the litter-colonizing
rnicroflora. This points to the most important effect of nutrient availability on the interaction between
fauna and rnicroflora in acid soils. The effect of the larvae on the ~ronase-extractableI4 Cfraction
(= labile N-rich organic compounds) shows that A. subfus~us'~romotethse accumulation
(mull) or the rapid turnover (moder) of the nutrients contained in the tissue of the microflora
in a soil specific way. In the limed moder soil, the humiphagous larvae shifted the balance between
soil microflora and litter microflora towards the soil microflora. In addition, A. subfuscus
accelerated the accumulation of N-rich compounds in the lirned soil.
