BIOMASS: Natuerliche Vielfalt von Mikroorganismen in Gewaessersystemen

Description: Das Projekt "BIOMASS: Natuerliche Vielfalt von Mikroorganismen in Gewaessersystemen" wird vom Umweltbundesamt gefördert und von Solvit durchgeführt. A total of 24 lakes sites will be selected along a North/South climate gradient (sensu TERI) from Norway to Spain and Northern Italy, incorporating also West/East gradient from Northern Ireland to the east of the Alps, to allow for differences between maritime and continental regions. These 24 sites will be sampled from two major defined study regions including - a north European group of 12 sites from Northern Ireland in the west to mid Norway in the east, including England, Northern Ireland, Scotland, Denmark and Norway. This region will be the responsibility of UCL. - A south European group of 12 sites from western France and Spain through the pre-Alps and Alpine areas of Northern Italy, Switzerland and Austria to Slovenia and eastern Austria. The Swiss and Northern Italy regions will be the responsibility of EAWAG, the other sites will be the responsibility of UCL. Leading Questions: The final goal of the programme is to generate a model allowing a prognosis of microorganism diversity changes in relation to global changes. To achieve this, we will 1. assess the diversity of lipids in lakes and the impact of environmental change (e.g. eutrophication) on this diversity, 2. develop and quantify the significance of lipids as markers of microbial diversity in the water column and in the sediment of lakes, 3. compare the microbial diversity changes as determined by the analyses of lipids with available historical limnological data and, in the absence of such data, with changes inferred from paleolimnological (fossil remains of diatoms, ostracods and cladocera) and geochemical data (e.g. fossil pigments) 4. develop and refine analytical methods on the molecular level to explore the relation between microbial diversity and biodiversity of ecosystems.
