Open AccessDirect and indirect effects of salinisation on riverine biota: a case study from river Wipper, Germany
Salinisation has direct and detrimental physiological effects on freshwater organisms, yet little is known about its indirect effects. Here, we present a study that investigated the primary and secondary effec...

Assessment and recovery of European water bodies: key messages from the WISER project
The EU-funded research project WISER (“Water bodies in Europe: Integrative Systems to assess Ecological status and Recovery”) developed new assessment methods required by the EU Water Framework Directive (WFD)...

Effects of physico-chemistry, land use and hydromorphology on three riverine organism groups: a comparative analysis with monitoring data from Germany and Austria
The majority of studies comparing the response of biotic metrics to environmental stress in rivers are based on relatively small, homogeneous datasets resulting from research projects. Here, we used a large da...

Open AccessEcological status assessment of European lakes: a comparison of metrics for phytoplankton, macrophytes, benthic invertebrates and fish
Data on phytoplankton, macrophytes, benthic invertebrates and fish from more than 2000 lakes in 22 European countries were used to develop and test metrics for assessing the ecological status of European lakes...

Upstream river morphology and riparian land use overrule local restoration effects on ecological status assessment
River restoration is a central issue of present-day River Basin Management. Unfortunately, many studies have shown limited ecological improvements, hypothesizing catchment influences and missing donor populati...

A new method for assessing the impact of hydromorphological degradation on the macroinvertebrate fauna of five German stream types
We developed a new Multimetric Index for stream assessment, which is mainly focussed on the impact of hydromorphological degradation on the macroinvertebrate fauna. The index was developed for five German stre...
