Effects of large-scale, climate-mediated oligotrophication on the food webs of Arctic and alpine lakes

The effects of climate change can be large in alpine and arctic lakes, since these ecosystems often are species poor and sensitive to disturbances.

The aim of the projects is to study the effects of ongoing climate change and nutrient depletion through a combination of analyzes of archived samples, lab experiments and field gradient studies.

The project will contribute new knowledge that can, among other things, be used to improve the basis for assessment of lakes and streams in the arctic regions.

For more information about the project, see the Swedish version of this page.
