The humus form is the expression of the equilibrium between litter production, litter decomposition and humification in a forest ecosystem, resulting from the biological action of bacteria, fungi, and soil fauna. The observed humus form reflects a...

The earthworm sampling records the abundance, biomass and species diversity of earthworms in the Kaltenborn site. Hereby all 16 plots where sampled. In every plot, four samples are taken, 2 in the 'no management' subplot (U) and 2 in the 'manageme...

This dataset contains the number of juveniles and seedlings were found in 16 subplots of 1m x1m, located in the central quadrant (in the upper half) of the main plot and estimation of percent stone cover, shrub cover, herb cover, litter cover, dea...

The NIRS spectra of the root samples as well as the calibration mixtures were analysed with a FTIR Spectrometer (Shimadzu IR Prestige-21, Kyoto, Japan), equipped with an integrating sphere (NIR IntegratIR, PIKE Technologies, WI, USA). Each spectru...

Most of the plant diversity in European forests is found in the understorey, and despite its relatively low biomass compared to the forest overstorey, its functional importance is high (nectar source for pollinators, habitat for small mammals, aff...

In summer 2011, we sampled sunlit leaves and needles from a subsample of dominant trees from each species (oak, beech, spruce & douglas) in the Kaltenborn site. These samples were oven drier for 48h at 60°C at INRA nancy. They were grinded and ana...
