Daniel Trauner is a river ecologist with a background on benthic invertebrates. His work started with studying benthic macroinvertebrate assemblages in Burkina Faso, West Africa, to test and develop bio-assessment systems for sub-sahelian water bodies. In the last years, his work focused on the Danube and its floodplains around Vienna, investigating ecological functions and processes, habitat diversity and benthic macroinvertebrates. He is experienced in biotic monitoring and habitat modelling of various aquatic and semi-aquatic species groups as well as using GIS and statistics software. In AQUACROSS Daniel will contribute to CS3 - the Danube Basin - and WP4.
