Master-/ Bachelorthesis (m/f/x) within the DFG
to support experimental work.
Objectives of the project are 1) whether the input of agricultural chemicals (pesticides, nutrients, trace metals) leads to a regime shift from a macrophyte-dominated clear-water state to a phytoplankton-dominated turbid-water state in aquatic ecosystems, 2) whether climate-change related temperature increase enhances the regime shift and 3) the identification of the mechanisms leading to this shift. This spring/summer we want to perform microcosm experiments including macrophytes and microalgae to investigate the role of two different exposure pathways, namely via the water column versus the sediment. Smaller pre-experiments should lead to an extended final experiment lasting four to five weeks. The main biological parameters to be investigated are the biomass and functions of the different compartments, but more advanced methods like metabolomics or metabarcoding are planned. This project requires background knowledge in aquatic ecology and/or (eco)toxicology. Proposed start in March/April.
