WORK PACKAGES: Microcosm experiment (Neuchâtel)

In microcosms the average depth to water table and amplitude of the fluctuation will be manipulated in 27 (replicated) mesocosms of 30cm in diameter and 60cm in length. We will place monospecific Sphagnum fallax lawns on peat cores. All mesocosms will be seeded with an extract of microorganisms from dry, intermediate and wet habitats (hummocks, lawns, pools). We will measure the growth of Sphagnum, decomposition and nutrient content (C, N, P) of Sphagnum fallax and Eriophorum vaginatum litter, soil respiration and structure of microbial communities (whole microbial communities including bacteria, fungi, micro-algae, protozoa and micro-metazoa by direct observation, with analysis of testate amoebae to species level, community profiles of bacteria, fungi and nematodes using T-RFLP). Samples will be taken at regular intervals to assess change in structure and function through time.
