We studied the influence of pedoclimate on the biological and morphological development of humus profiles in spruce forests on basaltic latite debris in the Southern Alps (Val di Fassa, Trentino, Italy). Four sites were selected differing in exposure (south-facing, north-facing) and altitude (1600 m, 1900 m) allowing paired comparisons (same altitude, different exposure vs. same exposure, different altitude). Measurements included abundance, species composition and vertical distribution of microannelids as well as polyphasic biochemical fingerprinting of soil microbial communities by denaturing gradient gel electrophoresis and phospholipid fatty acid analysis. The vertical distribution of microannelid abundance and microbial biomass showed similar patterns and provided evidence that the organic layer is the hotspot of biological activity in the studied humus pr...

This study addressed the possibility that DNA, like other organic molecules, could move vertically in the capillary fringe of groundwater aquifers. The targeted gene fragment used here was

The composition of bacterial and fungal communities was assessed by denaturing gradient gel electrophoresis (DGGE) of total and extracellular DNA extracted from all the soil horizons. Microbial biomass C and basal respiration were also measured to assess changes in both microbial biomass and activity
