I direct the Center for Macroecology, Evolution, and Climate at the University of Copenhagen and have an active interest in all its activities. My main personal research interests are patterns of species distribution, species range sizes, species assemblages, species richness and what determines such patterns (contemporary and historical factors or perhaps also just a bit of chance). Recent focus has been on the role of scale and conceptual formulation and practical design of null- and predictive models that allow direct testing of hypotheses related to patterns of diversity. The natural “other side” of my research relates how evolutionary and ecographical principles can be used to identify robust priorities for conservation of biodiversity.
