Background and activities

Post-Doc. in population ecology

My research focuses mainly on how spatial and temporal variation in the environment influence individuals and populations. I have in particular looked at how habitat characteristics such as forage availability and quality affect life history traits and habitat selection, and how individual responses to spatio-temporal variation in the environment in the end influence the population. My research is within the Centre for Biodiversity Dynamics (CBD) at Department of Biology, NTNU, with close collaboration with the Norwegian Institute for Nature Research (NINA) and Bioforsk
