Presentation
I am a researcher at the Department of Aquatic Sciences and Assessment, Section for Ecology and Biodiversity.
My research focuses on food webs, biodiversity and functioning of aquatic ecosystems. I am particularly interested in their responses to anthropogenic stressors (e.g. eutrophication, acidification, brownification, atmospheric nitrogen deposition, etc.) and climate change. My studies cover a broad range of ecosystems including lakes, ponds, rivers, and coastal waters. I frequently apply ecological tracers such as fatty-acid biomarkers and stable isotopes to investigate ecosystem processes and food-web dynamics in the changing environment, and assess the ecological impacts of multiple stressors acting together across space and time.
Research
My current research includes:
Development of an indicator for the assessment of nutrient depletion on benthic algal assemblages in Arctic/alpine lakes - Lead
Rapid climate change is driving shifts in the nutritional quality of aquatic food webs across the circumpolar North - Collaborator
Effects of browning of coastal waters on marine food web function and quality - Co-lead
