Phytoplankton and zooplankton in relation to Water Framework Directive status in some regulated lowland watercourses of the Scheldt and Sambre (France and Belgium)
Abstract Analysis of the composition, abundance and diversity of phytoplankton and zooplankton communities in channelised rivers from the upper Scheldt/Sambre catchment (France/Belgium) is used to assess the extent to which their distribution is related to Water Framework Directive (WFD) water quality criteria. Phytoplankton and zooplankton communities are differently associated with WFD status of the stations: phytoplankton communities differ between good/moderate and good/poor state, while zooplankton communities are different in poor than in moderate and good state stations. Euglenophytes are characteristic of good status, the rotifer Brachionus angularis of moderate status stations, and diatoms and the rotifer Brachionus calyciflorus of poor status. Phytoplankton blooms only occur in the poor status stations of the Scheldt, probably due to it having higher SiO 2 concentrations than the other rivers.
