4. Statistical tools for analyses of the data pool (based on R)

  • Accompanying species for a selected species
  • Habitat preference (EUNIS) of the selected species
  • Altitudinal distribution of the selected species
  • Ecological niche (light and moisture preference) of the selected species
  • Phenology of the selected species
  • Trait data (for all German species, own list can be uploaded)
