Dynamik Eines Düne-Moor-Biotops in Ihrer Bedeutung für die Biozönose

Abstract

In an ecotope (a dune-to-fen-landscape) of the Grunewald in Berlin in an area of sandy wuerm-moraines some researches were done on soilphysical and soilchemical aspects as well as trophi-cal and thermodynamical researches.

Special attention was paid to the seasonal changing of water conditions and air-content in the soil. The results permit a provisional interpretation of the zonal changing vegetation.

The thermodynamical measurements lead to the fact of an existing distinct micorclimate for each profile. Concerning the dynamic of nutrients and the trophical aspects, that landscape must be estimated as oligotrophe to mesotrophe.
