Background and activities
I did my Ph.D. at University of Copenhagen in 2000, and thereafter I spent 3 years at Arctic Station, Disko, Greenland, and 5 years at Climate Impatcs Research Centre, Abisko, Northern Sweden before moving to Trondheim. I study plant performance, community dynamics and productivity, and carbon fluxes and stocks in vegetation - all in response to different environmental drivers. Most of my work has been carried out in Arctic-alpine ecosystems, temperate-boreal forests and tropical savanna and the research focuses on how plant and plant community dynamics are responding to changes in climate, land use history and grazing. I work mostly in the field but can also be seen in the lab or greenhouse when needed. I right now work within three networks:
the Horizon 2020 project AfricanBioServices where I lead the work package on drivers of change in biodiversity and ecosystem function in the Greater Serengeti-Mara Ecosystem (Tanzania and Kenya). See more here: africanbioservices.eu
the Fleur network studying the impact of climate change to forest herbs along a latitudinal gradient from France to Northern Sweden see http://www.fleur.ugent.be
the ECOSHRUB network studying the effect of shrub encroachment on community dynamics and ecosystem processes in alpine tundra see www.ntnu.edu/biology/ecoshrub
In my group you also find:
Post doc: Stuart Smith
Ph.D. students: Kristin Odden Nystuen and Ronja Wedegärtner
and I cosupervise the Ph.D. students Koen Kuipers and Anders Kolstad
