Using a multi-trait approach to manipulate plant functional diversity in a biodiversity-ecosystem function experiment.

A frequent pattern emerging from biodiversity-ecosystem function studies is that functional group richness enhances ecosystem functions such as primary productivity. However, the manipulation of functional group richness goes along with major disadvantages like the transformation of functional trait...
