Background and activities
Researcher in population ecology at Centre for Biodiversity Dynamics (CBD)
My research focuses mainly on how spatial and temporal variation in the environment influence individuals and populations. A central question is how individuals relate to their habitat and resources, and individual behaviour and the consequences this has for individual fitness. Systems for these indivudal-based studies include moose at the Vega island in northern Norway, and in chamois and ibex in the Swiss national park.
At larger scale, I am interested in what causes variation in demographic rates among populations, and how shared environmental signal causes co-fluctuations in population dynamics. However, even when the environment is strongly correlated over large distances, we still often observe low synchrony in population dynamics. Understanding mechanisms causing population syncrhony, or lack of such, is something I also look into.
