Biotic and abiotic drivers of macroinvertebrate dispersal (A16)

• 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

A16 will perform a comprehensive field dispersal experiment for selected hololimnic and merolim-nic as well as dispersive and philopatric species in both model catchments (Emscher/Boye, Kinzig). The distances crossed by individual members of a population will be quantified by an array of in-stream and terrestrial dispersal traps. Isotope enrichment (15NH4Cl) upstream of dispersal sites will be used to label large quantities of the model species’ populations. Comparing the urban Em-scher/Boye catchment with the rural Kinzig catchment will allow to address catchment-related characteristics and stressor history on dispersal patterns.
