The Helmholtz Centre for Environmental Research (UFZ) with its 1,100 employees has gained an excellent reputation as an international competence centre for environmental sciences. We are part of the largest scientific organisation in Germany, the Helmholtz association. Our mission: Our research seeks to find a balance between social development and the long-term protection of our natural resources.
The PhD-project is embedded in the joint German – French DFG-ANR-project ‘CLIMSHIFT’: Regime shifts in freshwater ecosystems exposed to multiple stressors by increasing temperature, fertilizers and pesticides.
PhD position (m/f)
Subject: Assessing the combined effects of multiple stressors (agricultural run-off and climate change) on aquatic plant communitiesProject start: 1st May 2018; working time: 65% (25.35 hours per week), limited to 3 years.
The aim of the DFG-project is a mechanistic understanding of combined effects of climate change and agricultural run-off (organic and inorganic pesticides plus nitrate) on shallow aquatic systems. We aim to investigate the complex interactions between different aquatic plant functional groups (microalgae and macrophytes) and related regime shifts in small aquatic systems. Therefore we will perform micro/mescocosm studies with communities of different complexity (benthic and pelagic primary producers and related consumers) and different stressor settings (individual and combined). Next to structural analysis of plant communities, we want to use functional and metabolic response factors to quantify ecosystem metabolism and dynamics and to identify critical thresholds of stressor interactions.
