Description: Das Projekt "Einfluss von Wasser auf die Erhaltung von Lipiden in Böden" wird vom Umweltbundesamt gefördert und von Universität Bayreuth, Fachgruppe Geowissenschaften, Bayreuther Zentrum für Ökologie und Umweltforschung (BayCEER), Lehrstuhl für Agrarökosystemforschung durchgeführt. Changing precipitation patterns i.e. an increase in intense rain events during the winter season and a higher frequency in drought conditions during the summer season, are predicted in the near future within Central and Western Europe. The influence of such climate changes on plant, microbial biomass and organic matter in soil are not completely understood. Our collaborative (UK/German) research programme will focus on the incorporation, degradation and preservation of plant and microbial derived lipids present at different depths in grassland soils. We will compare the lipid composition and preservation in grassland soils under stagnic (permanently wet) or drained (more frequent drying and rewetting) conditions. New shared approaches, including isotopic tracers like 15N, 13C, and 14C (latter only laboratory.) at the molecular level, will be used by both UK and German members of the research team in number of linked collaborative field and laboratory experiments. In collaboration with Roland Bol, Jennifer Dungait, Liz Dixon (all North Wyke Research, Okehampton, UK) and Richard Evershed (University of Bristol, Bristol, UK).
