"Plankton biomass and composition, extracellular phosphatase activity (EPA) of planktonic microorganisms, aluminium (Al) speciation, and phosphorus (P) cycling were studied in acidified lakes of different trophy in the Bohemian Forest. Enormous EPA and high planktonic C:P ratios suggested severe P limitation of the plankton. The terrestrial Al inputs, together with in-lake processes controlling the formation of particulate Al reduced P availability for planktonic microorganisms. Ionic Al reduced EPA at pH <5. Both particulate and ionic Al forms affected P availability, specifically shaped the plankton composition in the lakes, and delayed plankton recovery from acidification. The study demonstrated the key role of Al in overall P availability, food web structure, plankton dynamics, and recent recovery of chronically acidified lakes." . "61" .
