I have always been interested in understanding how animal respond to their dynamic environment - a system including humans, which builds the red thread in both my education and research. Addressing research questions that combine behavioral, physiological and spatial ecology thus create the optimal link to feed my interest. Today, human activity increasingly expand into wildlife habitat, which not only increases the frequency of contacts between wildlife and humans year-around, but also leaves long-lasting ecological footprints in wildlife habitat. Next to this dynamic, changed climatic conditions and land use affect wildlife. The overarching goal of my research is to improve our understanding of the ecological effects of the structure and the dynamics of human activity on wildlife (recreational activities, infrastructure) in relation to the surrounding environment. I also work with traffic safety questions. Here, I study the distribution of wildlife-vehicle collisions in space and time and in relation to animal’ movement and distribution. Within my area of research, I combine empirical and GIS-based approaches and use statistical and spatial analysis.
I am course leader for two global wildlife ecology courses at our department; "Wildlife ecology in a changing world – pre-requisites and challenges". Next, to lectures in these two courses, I am teaching also in other courses at SLU, addressing topics on spatial and behaviroal ecoloy of wildlife, human-wildlife interactions, and wildlife management aspects.
Recent projects I have been involved in considered the movement behavior and resource utilization of sympatric living moose and reindeer in the mountainous landscape as well as the impact of wind park development on the spatial distribution of reindeer. Currently, I am part of the Swedish Energy Agency financed project ”Hållbar landbaserad vindkraft - synergi, integration eller konflikt mellan riksintressen” (project leader Johan Svensson) that focus on synergies and conflicts among different land use interests in relation to wind power. I am also part of the Swedish EPA financed project Beyond Moose (project leader: Joris Cromsigt) that focus on ungulate interactions in multi-species systems and their impacts on surrounding environment in human-modified landscapes. Currently, I am leading two moose marking projects in the county of Norrbotten: ”Förvaltningsmärkning Älg Norrbotten - vilt och skog” and the moose marking project around the mountain village Nikkaluokta (latitude 67) where we study the effects of climate on larger herbivores. In each project, we study intensively the spatial ecology of moose and compare with behaviour that we observe in other moose populations. I have been project leader of the finished project “Älg och rådjur i stormarnas spår” that focused on spatial ecology of both moose and roe deer following the storms Gudrun (2005) and Per (2007) in the county of Kronoberg. Having data from southern and northern landscapes allow us to address questions along a north-south gradient. Data on different marking projects in Norrbotten enable also studies of meta-populations dynamics.
