Background and activities


Centre for Biodiversity Dynamics (CBD)


Main research interests

Population ecology, community ecology, behavioural ecology, trophic (e.g. plant-herbivore) interactions.


Current main focus

The project "Predicting effects of climate change on Svalbard reindeer population dynamics - a mechanistic approach" (REINCLIM) has received funding for the period 2012-2015 from the Norwegian Research Council (NORKLIMA programme). The goal is to apply a multi-disciplinary approach to understand and predict climate change effects on arctic ungulates, using high-arctic reindeer populations at Svalbard as a model system. REINCLIM is run by CCB at NTNU (Brage B. Hansen), and project partners include the Norwegian Meteorological Institute, James Hutton Institute, University of Aberdeen, Norwegian Institute for Nature Research, Norwegian Polar Institute, Northern Research Institute, Norwegian University of Life Sciences, Norwegian School of Veterinary Science, and the University Centre in Svalbard.
