Introductione the mineral composition is mostly geogene and only to a minor extent affected by the organisms of the ecosystem at time scales relevant to ecosystem research. The element release by irreversible weathering of minerals is then seen as an external input (Ulrich 1992).

Phyllosphere Ecology in a Changing Environment: The Role of Insects in Forest Ecosystemsm as a gigantic ‘black box’ (Grimm 1995) whose behaviour is independent of its history (Higashi and Burns 1991) (.). Ecologists, in contrast, working with organisms, populations or communities, are concerned with specific adaptations, species interactions, community structures and population dynamics in an evolutionary context (.).

The Lehstenbach and Steinkreuz Catchments in NE Bavaria, Germany. The summits of the Fichtelgebirge, Schneeberg (1,053 m), and Ochsenkopf (1,023 m) do not reach the timberline. The mountain ridge acts as a main European catchment between the Atlantic North Sea and the Danubian Black Sea.

Fog Deposition and its Role in Biogeochemical Cycles of Nutrients and Pollutantssition may be as high as, or even higher than, the deposition through rainwater (e.g., Saxena and Lin 1990). There is a large variability in physical and chemical conditions of fog events, so that any estimates of their potential roles in biogeochemical cycles must be studied individually for each site and each time period of interest.

Element Fluxes with Litterfall in Mature Stands of Norway Spruce and European Beech in Bavaria, Sout the accumulation of humus and nutrients. Few larger studies have been made on litterfall on a European basis. For needles of Norway spruce and different pine species, Berg and Meentemeyer (2001) made a study covering the main part of western Europe, whereas for European beech, for example, few values have been published.
