Diet-consumer interactions under variable stressor conditions as revealed by stable isotope stud-ies of individual amino acids (A13)

• Subject Area: Hydrogeology, Hydrology, Limnology, Urban Water Management, Water Chemistry, Integrated Water Resources Management
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426547801

A13 will use food webs derived from compound specific stable isotope analysis (CSIA) of amino acids to unravel species’ niches and trophic links under conditions of multiple stressor increase and release. A simplification of food webs with fewer trophic levels under stress conditions is expected, which will be reflected in δ15N of trophic and source amino acids. A temporal and spatial recovery gradient in the Emscher/Boye catchment will be sampled.
