Researches and teaches ecology and biodiversity, with special focus on community assembly, with a preference for plants and their associated biota of insects and fungi, and on evidence-based nature conservation.

Primary fields of research

Community assembly and species richness

• environmental control (productivity, disturbance) vs. neutral effects

• species pools and the niche

• diversity-invasibility relationships

• diversity-productivity relationships

• community phylogenetics

• Vegetation ecology of temperate, alpine and arctic plant communities

Population ecology

• Regional (source-sink dynamics, metapopulations, remnant populations, range margins)

• Local (vegetative and sexual recruitment, longevity)

• Reproductive biology

• Seed dispersal, especially by mammal endozoochory

Evolutionary ecology

• allometry of seed size and seed number per individual

• habitat specialization

• niche conservatism

Landscape ecology

• Influence of land-use history on species richness, distribution and genetic diversity of populations

Conservation / restoration

• Conservation and restoration of temperate vegetation, especially grasslands

• Invasive plant species (mainly Rosa rugosa)
