Description:
A field experiment was carried out to simulate effects of eutrophication on the benthic community of a sandy tidal flat in the Wadden Sea. A new device, the pore-water manipulator, was used to enhance pore water concentrations of phosphate and ammonium during a period of 18 weeks. The microphytobenthos responded with a significant biomass increase which lasted during the entire experiment. The species composition
changed and particularly cyanobacteria of the genus lvferismopedia increased. The experiment indicated that the microphytobenthos was N-limited. Meio- and macrofauna showed no reaction on the increased microphytobenthos biomass. It is supposed that the food availability for the fauna did not improve
because the groups of algae taking over are hardly grazed.
