Project groups


This project investigates the impact of predicted changes in water-temperature and oxygen-content resulting from global warming on benthic invertebrates. A metadata-analysis is used to determine the relevance of these two factors for central-European streams. Laboratory experiments and field studies on selected model-organisms are also being conducted. The primary aim of the project is to predict the impact of water-temperature and oxygen-content on macroinvertebrates in Central-European streams.


• Compilation of geocoding data on water-temperature, oxygen-content and other important abiotic parameters including macroinvertebrate-data

• Performance of laboratory experiments to obtain information on the effects of temperature and oxygen on model-species
• Performance of vivo experiments on temperature and oxygen-content in variously impacted streams
• Predict on of the impact of changing stream-temperatures and oxygen-content on macroinvertebrates
• Development of a risk analysis for selected model-organisms

• Projection of the obtained results to other benthic invertebrates
