The Jena Experiment is a large scale long-term field biodiversity experiment which involves collaboration between ten research institutions in Germany and Switzerland, coordinated by the University of Jena and the Max-Planck-Institute for Biogeochemistry, Jena.

The Jena Experiment website can be acessed here.

Experimental design

For details of the experimental design, see Roscher et al. 2004.

A total of 405 grassland communities were established from seed on a 9 ha site in Jena, Germany, differing in plant species richness, composition and number of functional groups (grasses, legumes, large herbs, small herbs).

The species assemblages serve as basis to study interactions not only among plant individuals and plant species, but also among different trophic levels. Our emphasis is on ecosystem aboveground productivity, ecophysiology and population biology of individual species, and the turnover of nutrients.
