Biological recovery from acidification and saturation of ecosystems with nitrogen
Biology Centre AS CR, Institute of Hydrobiology
Target 1 – To outline the limits of surface water chemistry, which are necessary for biological recovery of each ecosystem component (plankton, benthos, fish) and generalisation of these limits to sites of the Levels II and I.
Target 2 – To monitor the biochemical transformation of N in soils and isotopic composition of tree rings and to find the most suitable monitoring tools for evaluation of the level and duration of ecosystem saturation with N.
