Relating productivity patterns to functional diversity of North Sea macrofauna – knowledge increase by functional focus?
The benthic compartment is central to ecosystem services in shelf seas. Assemblages with a higher diversity have been suggested to operate more effectively. However, there is no general ecological relationship between diversity and ecosystem functioning due to species-specific effects and environmen...
