The aim of my research is to broaden the understanding of how climatic changes may affect the Arctic inter-tidal communities in terms of species composition, distribution and biomass. Blue mussels (Mytilus edulis) are excellent harbingers of the effects of future climatic changes. I therefore use mussel populations from Greenland, Iceland, Svalbard, Russia and Denmark to investigate how this key species physiological adaption to the Arctic environment translate into defining distribution limits, abundance patterns and potential range shift.
I’m also interested in the ecological consequences of the invasive species in the Arctic and aim to expand our knowledge of how invasive species will influence current ecosystem structure and function in a warmer Arctic. My work on three functional levels: organisms, populations and communities are necessary to progress current understanding on the processes that link Arctic climate change with changes in biological structure.
I collaborate with researcher from around the world. Current collaborations include University of British Columbia (CA), University of Manitoba (CA), Aarhus University (DK), University of Toulouse (FR), University of Western Australia (AU), Greenland Institute of Natural Resources (GL), Institute of Oceanology Polish Academy of Sciences (PL), Arctic University of Norway (NO) and Technical University Denmark (DK).

The future of Arctic biodiversity in a climate change era
The overall aim of the project is to investigate how biotic interactions combined with physiological performance underpin community sensitivity to changing environmental conditions in the Arctic. The project focuses on leading-edge populations, and investigates community sensitivity under different conditions perpetrating several stressors simultaneously. The project focuses mainly on intertidal communities, but can readily be expanded to include subtidal and the wider marine ecosystems.
