  • Entomology
  • Ecology
  • Biodiversity


  • Regulation of interacting species and maintenance of biodiversity in ecological communities
  • Understanding spatial patterns of relative abundance and species richness, and the factors that promote or impair local population persistence and species coexistence in ecosystems, especially among the hyper diverse insects and invertebrates
  • Conceptual research at large scales as well as local phenomena in 'natural' and managed ecosystem
  • Species interactions constrain community diversity, function, and invasion
  • Roles of history, evolution, genetic structure, and biotic interactions in assembling diverse, functional communities
  • Variation in food web patterns across patches, landscapes, ecosystems, and over time, and their resilience of these structures to perturbation
  • Use of knowledge of ecology to predict and ameliorate the manifold impacts of humanity
  • Responses of Coastal Ecosystems to Rapid Environmental Change
  • Synthesis of Trophic Interactions and Cascades across Ecosystems
  • Nematodes, Microbes, and the Little Things That Run the World beneath our Feet
