Abstract

The objective of this thesis was an eco-exposome analysis of physiological changes in the amphipod Synurella ambulans as a response to environmental stressors in groundwater connected ecosystems. Life history trait analysis revealed spatio-temporal variation in growth parameters and the influence of environmental parameters, especially water temperature, concentrations of dissolved oxygen and organic matter. The species accumulated metals from the environment even when metal concentrations in interstitial water and sediments did not deviate from environmental quality standards. Increased bioaccumulation factors, biomarkers of antioxidant defense and exposure to xenobiotics, lower levels of adenylate energy charge and a lower PK/PEPCK ratio in S. ambulans downstream of the wastewater outlet compared to the upstream location, indicated a negative anthropogenic influence and increased anaerobic potential. S. ambulans is a suitable bioindicator for environmental assessment in the hyporheic zone, which is important for the protection of this vulnerable ecotone that is essential for freshwater ecosystem services.
