Lay Summary (English)

Lead
Lay summary
Recent research has demonstrated that biodiversity influences ecosystem functioning including regulation of nutrient cycles. Consequently, the current unprecedented loss of biodiversity might deteriorate the functioning of ecosystems and thus also the services ecosystems supply to humankind like biomass production, water cleaning or efficient resource use.The objective of our project which contributes to a large research consortium of several German, Swiss, Dutch and French research groups ("The Jena Experiment", http://www.the-jena-experiment.de/) is to explore the reasons for observed relationships between plant diversity in form of species or functional richness in an experimental grassland and elements of the N and P cycles. In particular, we search for the unknown sources of enhanced N accumulation and N supply in soil with increasing biodiversity. We address gaseous N deposition, nutrient uptake from groundwater and gross mineralization (i.e. release of nutrients by microbial oxidation of soil organic matter). Furthermore, we continue a long-term observation of all relevant ecosystem fluxes (rainfall, soil water input, flow in soil, internal cycling between soil and vegetation) started in 2002.The location of the experiment is in the German city of Jena, on a flat area near the river Saale which was previously used as arable land. At the study site, in 2002 a large experimental grassland was established containing different plant mixtures varying in species number (from 1 to 60) and number (from 1-4) of functional groups (i.e., legumes, grasses, and small and tall herbs).We will combine field experiments in Jena with laboratory experiments in Berne andMontpellier where we cooperate with a French research group. In the field we monitor all major water and element fluxes with rainfall collectors and suction plates installed at different soil depths and furthermore conduct an experiment in which we follow an isotopic label of N to determine the gross mineralization. In the laboratory, we incubate soil cores from the field site to catch all details of the N transformation and we contribute to a joint lysimeter experiment with large soil monoliths excavated at the field site in Jena and transported to the new ECOTRON facility in Montpellier in which we try to quantifiy the N input via gaseous deposition and uptake from groundwater.Our work will provide new information about the relationship between biodiversity and ecosystem functioning which will (1) promote the protection of highly diverse ecosystems and (2) help in designing improved land-use systems e.g., by substituting fertilizer inputs by plant diversity in grassland.
