"We suggest to study spruce swamp forest (SSF, Central Europe) internal heterogeneity related to soil microbial community functioning, soil organic matter (SOM) and dissolved organic matter (DOM) quality and quantity. In SSF, spruce and peat mosses are responsible for peat accumulation and the related high soil water retention. The patchy co-dominants, cotton grass and dwarf shrubs, bring internal SSF spatial variability and affect the functioning of the whole SSF in the way they acquire, process and invest resources. However, it is still unknown if this spatial heterogeneity is reflected in the functional diversity of soil microorganisms and ongoing soil processes, which affect DOM quality. We will study effect of cottongrass and blue berries on SOM, DOM and microbial functioning at three SSF sites using chemical, microbiological and molecular methods including stable izotopes probing, and pyrosequencing. DOM will be analyzed by fluorescence spectral analyzes, size exclusion and ion chromatography. Manipulative field and laboratory experiments will complete field measurements."@en .
