Testing the European Stream Typology of the Water Framework Directive for Macroinvertebrates,large differences between the participating countries concerning the number of taxa, the number of specimens and the taxonomic resolution. The data, including macroinvertebrates and environmental variables were analysed by using Canonical Correspondence Analysis (CCA). The observed macroinvertebrate

Comparing Macroinvertebrate Indices to Detect Organic Pollution across Europe: A Contribution to thto compare the results of different benthic macroinvertebrate metrics used to assess the impact of organic pollution (including eutrophication) (one of the major human impacts on European streams). A selection of the data sampled in the AQEM project was evaluated, where benthic macroinvertebrate- an

Validation of reference conditions showed differences between classification of sites as reference sites based on criteria to be used in the field and directly interpreting environmental or biological data and the result of the final assessment sys

To correlate faunal metrics and hydromorphological degradation, a ‘Structure Index’ describing the alteration of stream morphology was generated. A correlation matrix of the selected metrics and the structure index ispre

Assessing Acid Stress in Swedish Boreal and Alpine Streams Using Benthic Macroinvertebrates,hree new multimetric acid indices using benthic macroinvertebrates were developed for the AQEM project. These, together with a large number of other benthic macroinvertebrate indices including a number of indices aimed at detecting acid stress, were evaluated for their ability to detect acid stress,

The developed metrics showed high correlations with each other. Hence, BMG seems to be suitable for the ecological quality assessment of Greek running waters affected by nutrients.
