Abstract

This work/dataset addresses human stressors and their impacts on fish assemblages in the Austrian Drava and Mura River Basins. It supports the EU-project MARS (Managing Aquatic ecosystems and water Resources under multiple Stress) by analysing single and multiple stressors, environmental effects and stressor combinations/interactions. Data sources are mainly shape files and MS ACCESS databases. With the help of point data on connectivity disruptions (barriers) and line data on hydromorphological & water quality stressors (on water body level), six mainly hydromorphological stressors from the national inventory assessment of the EU Water Framework Directive were recoded and aggregated into new variables, i.e. stressor metrics. These then were compared with point data (fish sampling sites) and related information on fish assemblages (Fish Index Austria and related single metrics as well as the WFD biological and total status).
