"In the last few years it has been suggested that also genetic diversity within species is important for ecosystem function. In this project we plan to explore the effect of genetic diversity and genet spatial structure of grass species (Festuca rubra) on community structure and stability. Questions: (1) What is the effect of genetic diversity on productivity, stability and resistance to invasion? (2) Are the observed patterns due to complementarity or sampling effect? (3) Do the conclusions differ between environments and depend on time since the experiment was established? (4) What is the effect of spatial arrangement of the clones? We plant to answer these questions in a garden experiment with two nutrient regimes and three genetic diversity treatments: mono-clone, six-clone and eighteen-clone. To be able to separate the sampling and complementarity effects in a community, the clone identification by means of microsatelite or allozyme markers will be necessary."@en . . . . "1"^^ . "2"^^ .
