Effects of multiple stressors on food web architecture and processes (A12)
Subject Area
Hydrogeology, Hydrology, Limnology, Urban Water Management, Water Chemistry, Integrated Water Resources Management
Term
from 2021 to 2024
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 426547801
A12 will address food web metrics, derived from bulk stable isotope samples, as response variables to estimate multi-functionality of communities in response to degradation and recovery, detect trophic niches and estimate trophic interactions. It will analyse the effect of degradation on the food web architecture by comparing communities at sites under different stressors with communi-ties at reference sites. Effect of recovery on food web architecture will be estimated by analysing a long-term dataset on recovering streams. A trait-based approach will be applied to link the trophic niches of species to their traits to explain loss and gain of trophic niches under stress and stress release.
