We study the ecological and genetic mechanisms by which life diversifies – diversification within a species, speciation and large species radiations. We also study adaptive radiations in a community ecology context and we wish to understand how adaptation, speciation and adaptive radiation affect species richness and ecosystem function. We also work on effects of environmental change on species assemblages built to variable extents through immigration and through speciation. Eventually we would like to know why different evolutionary lineages vary so enormously in their diversity and in their responses to environmental change across scales of space and time.
