Biodiversitet, marin økologi, bunndyrssamfunn, fiskesamfunn, antropogen påvirkning, effekter av klimaendringer på økosystemer
The main part of my research activities is focused on biodiversity, its measurement and patterns, human impact and impacts of climate change on ecosystems. I have studied marine biodiversity patterns in different parts of the world in shallow waters, on the continental shelf and in the deep sea using data on benthos and fish communities. The work implies a large number of collaborations with scientists from Europe, New Zealand, Canada, Russia and China. Currently I am also focusing on terrestrial biodiversity studies. With regard to the measurement of biodiversity, I have focused on beta diversity, patterns of rare and common species and, in general, on the use of multivariate analyses.
