Brief description of the main scopes: 
  • Restoration ecology: impact of habitat restoration and management on plant and animal diversity.
  • Community ecology: organization of animal communities, formation and operation of landscape-scale patterns in biodiversity.
  • Systematic conservation planning: optimal conservation of European freshwater biodiversity.
  • Theory and practice of biodiversity monitoring, scale-dependence of conservation strategies.
  • Evolutionary ecology of plant-animal seed dispersal mutualisms.
