3 Forest Ecosystems Are Influenced by the Changing Biogeochemical Cycles 

TABLE 8 Overview of Possible Impacts and Risk Potential of Anthropogenic Changes in Global Biogeocheniical Cycles ( f, Increase , Decrease, No Change).  

I N-contents, f Mineralization, f N-tiirnover, NPP, N surplus, I Mycorrhiza, f /1 Humus layer 

I damage of fine roots and mycorrhiza, I cation leaching 

I loss of ecosystem functions Reactions are very site specific and independant of species, e.g., -/1 NPP of vegetation, changes in stocks and site composition (C,-, Q-plants), species-related changes in population of herbivores Changes in site composition, loss of biodiversity,
