Description
| - 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.

- Biomasa a složení planktonu, aktivita extracelulárních fosfatáz (EPA) planktonních mikroorganismů, speciace hliníku (Al) a koloběh fosforu (P) byly studovány v acidifkovaných šumavských jezerech o různé trofii. Enormní EPA a vysoké C:P poměry ukazovaly na výraznou P limitaci planktonu. Terestrický přísun Al, spolu s procesy ovlivňujícími tvorbu partikulovaného Al v jezerech, redukovaly dostupnost fosforu pro planktonní mikroorganismy. Iontový Al redukoval EPA při pH <5. Partikulované i iontové formy Al ovlivňují dostupnost P, specificky působí na složení planktonu jezer a zpomalují zotavování planktonu z acidifikace. Studie ukázala klíčovou úlohu Al pro celkovou dostupnost P, strukturu potravních sítí, dynamiku planktonu a probíhající zotavování chronicky acidifikovaných jezer. (cs)
