Professor of Botany
My main research topic is macroecology of biodiversity. I am trying to look beyond the borders of the existing paradigm. I'm studying evolutionary and landscape history of ecological communities, elaborating new theories, methods and approaches. I have been intrigued by linking large- and small-scale processes with biodiversity, especially the species pool concept globally but also the effect of spatial heterogeneity. During the recent years I have developed the dark diversity concept. Besides taxonomic diversity, I have worked with genetic, functional, phylogenetic and below-ground diversity. My research themes have been global plant communities, but especially grasslands in different continents. In addition to leading the workgroup I serve as editor for Journal of Vegetation Science and Applied Vegetation Science.
