Research Questions

Our research group studies patterns and causes of biodiversity at multiple scales, ranging from variation in the diversity of species’ traits to gradients in the assembly, diversity and dynamics of ecological communities across the planet. We explore theories to explain why changes in biodiversity through space and time emerge through the interplay of fundamental processes of community ecology (speciation, dispersal, ecological drift & niche selection). We combine field experiments, large-scale and long-term observational studies, and ecological modeling in a wide range of plant communities (forests, grasslands, montane ecosystems, savannas) spanning temperate and tropical ecosystems to explore the following questions:
