Bakgrunn

My research interests span a broad spectrum of ecological and evolutionary topics, most of which are rooted in population biology. Before the early 1990s, much of my work was purely theoretical. Later, I have adopted the research strategy of 'asking' available data what the underlying ecological or evolutionary process might most likely be - all within a theoretical perspective. I strongly favour comparative studies - by comparing similar features between different (but comparable) systems, we typically learn more than we otherwise would have done. Variations in population densities in time and space - and the underlying demographic processes - have been a main interest of mine over the years. An important example is the interdependent relation between density-dependent and density-independent processes, where the ecological effect of climate is an important example of the latter. Most of my work relates to basic issues. (I have never claimed that my research is of any immediate use, although I do hope it will be in the long run.) However, I find great pleasure in working on more applied issues as well; I have never been ashamed of my research being of practical use here and now. These applied interests have brought me into work on pest control (e.g., rodents in Africa), harvesting (marine and terrestrial), bio-economics (e.g., the ecological dynamics of dry-land pastoral systems) and epidemiology (Plague). I do believe that it is helpful to try to understand what has happened in the past, in preparing for what might happen in the future, e.g., ecological and evolutionary effects of climate change. For this reason, I value the existence of long-term time series - and the analysis of them. I love interacting with colleagues, and find great pleasure in building and maintaining teams. I am an ISI highly cited researcher, and had the January 2004 'hot paper' in ISI's Essential Science Indicators. I am an elected member/fellow of the Norwegian Academy of Science and the Letters, DNVA, the Royal Norwegian Society of Science and Letters, DKNVS, Academia Europaea, French Académie des Sciences and the Finnish Society of Sciences and Letters. I also do quite a bit of editorial work, including as Associated Editor of Proceedings of the Royal Society, Series B and as Editor-in-Chief of Climate Research..
