Hans Henrik Bruun

Associate Professor

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)
