Research
Conservation of aquatic biodiversity
Freshwater ecosystems are biodiversity hotspots, harbouring 10% of all species in only 1% of the total earth surface. At the same time, freshwater ecosystems are heavily impacted by climate change, over-exploitation and pollution, threatening this biodiversity. In Germany, more than 50% of the fish species are now on the IUCN red list. Molluscs and fish have the highest proportion of species in a bad conservational status following the European FFH directive. Consequently, the protection of aquatic species is of the highest importance. I therefore aim to identify key factors for a positive population development of threatened species (Thick shelled river mussel, Grayling, European nase).
Food web interactions in streams
Predator-prey interactions or predator effects on benthic community composition and ecosystem functions are not often studied in streams. Nevertheless, predators can have strong direct and indirect effects in stream ecosystems. A high predation pressure of piscivore birds (e.g. cormorants) can indirectly increase eutrophication effects by causing algae blooms and clogging of the hyporheic zone and thereby reducing the quality of the stream habitats for benthic invertebrates. In field surveys and experiments I therefore study predation effects with the aim to integrate species interactions into assessment and conservation of streams communities.
Anthropogenic effects on benthic invertebrates
Streams are heavily impacted by anthropogenic stressors due to exploitation pressure and because catchments spatially integrate land use effects. Besides hydro-morphological degradation and increased nutrient inputs, micro-pollutants can impact ecological stream quality. I aim to develop biological indicators for such stressors and to analyse ecosystem scale effects.
Ecological stream restoration
In the last years a rising number of restoration projects is implemented to increase ecological quality of streams and conserve aquatic biodiversity. Successive measures need a deep understanding of aquatic ecosystems and can usually not planned by local managers alone. Instead an intensive cooperation between praxis partners and scientists is needed for successful restoration measures and to efficiently use the available financial means. Within this frame, we support different stream restoration projects and monitor their ecological success.
