Structure and function of below-ground (micro-)biome in rewetted fens– a trophic latch? (A04)

• Subject Area: Organismic Interactions, Chemical Ecology and Microbiomes of Plant Systems ; Microbial Ecology and Applied Microbiology
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 531801029

We will analyze the structure and function of the below-ground (micro-)biome in rewetted fens. (1) Using > 100 rewetted Screening Sites we will create the first broad census of below-ground biota in rewetted fens. (2) Spatially and temporally resolved sampling and analysis of Core Sites will enable an understanding of the spatio-temporal microbiome dynamics. (3) To verify the hypothesis of a trophic latch on C mineralization, we will conduct microcosm and mesocosm experiments with peat microbiota and model plant species under oxic and anoxic conditions. (4) NGS and amplicon profiling services will be provided for other subprojects.
