Beskrivning av projektet
While the individual effects of climate change and intensified land use have received much attention, their relative importance and potential interactive effects on freshwater biodiversity and ecosystem functioning remain poorly known. Nutrient enrichment is a pervasive stressor in streams worldwide and, in the future, it will co-occur with climate-change induced factors (increased water temperature, altered hydrological regime). This project examines such interactive effects on stream ecosystems using a combination of manipulative mesocosm and field experiments, field surveys along anthropogenic gradients (nutrient addition; hydrological disturbance) and hydrological modeling. I also test whether in-stream restoration could mitigate the negative impacts of climate change. All tasks measure multiple taxonomic groups (bacteria, fungi, benthic invertebrates) and ecosystem processes (primary production, decomposition, biofilm metabolism).
