My research is aimed at understanding multiple stressors in boreal headwater streams. I am specifically looking into the effects of extreme hydrological events (drought and flooding) on organisms and ecosystem functions in streams that already experience land-use pressures from forestry.


Land-use and climate change represent severe pressures on northern streams. The combination of these anthropogenic pressures becomes more pronounced, as prolonged droughts and intense floods are increasingly more common. At the same time, forestry pressures are intensifying. The objective of my PhD is to investigate the combined effects of these pressures on stream organisms and ecosystem functions.

For this research I collect data from experimental manipulations in mesocosms and natural streams. Aspects of stream ecology that I am interested in include of macro-invertebrate communities, metabolism, algae production and leaf litter decomposition.

Most of my data will be collected at Svartberget in the Krycklan Catchment Study where I have access to the experimental fluvial facility and natural streams with dam infrastructure.
