You prepare a doctoral thesis in the field of aquatic ecology and biogeomorphology of rivers. The PhD is an extension of our present research, both experimental (e.g. in-situ and field flumes) and numerical modeling, in the field of plant-flow interactions and how this is structuring river ecosystems. The yearly development of macrophyte biomass and its spatial distribution is central in lowland streams: the ecosystem is ‘engineered’ by macrophytes that create large variability in flow velocities and geomorphology of the river. Macro-invertebrates play a key role in the transfer of energy from the organic matter to higher trophic levels (like fish). Central question is how the macro-invertebrate community (seasonally) develops and is maintained within vegetated streams and their role in the foodweb.
This will be studied in-situ (in Flanders and Poland) and in laboratory experiments. Stable isotope studies (natural abundance) will be applied to elucidate the food web assemblage in these riverine systems. Developed knowledge will be implemented within existing 2D river ecosystems models to understand macro-invertebrate dynamics and to analyze both scientific and management issues. Fundamental are the boundary conditions for development and maintenance of macro-invertebrate communities in changing climatic drivers and concerning management the question is what is the impact of yearly vegetation mowing on the development of macro-invertebrate communities and energy flux in the system. This will be a continuation of existing field research and modeling studies in close interaction with other researchers in the research group for Ecosystem Management (Department of Biology, Faculty of Sciences) as well as with the Laboratory of Hydraulics of the University of Ghent, Flanders Hydraulics and the Warsaw University of Life Sciences.
