Abstract of the PhD thesis as part of the project WETSCAPES

Peat is mineralized in drained peatlands and is decomposed to the greenhouse gas nitrous oxide (N2O) and to N2. These processes of degradation are poorly known. Especially the dynamic of the N2O- and N2 production are still insufficiently investigated. Studies concerning the processes of N2O-development lack nearly completely. The most assumed process for the production of N2O is the denitrification, which can be implemented by different microbial groups like fungi, autotrophic or heterotrophic bacteria, and consequently, they react different to environmental influences. New isotopic methods for the distinction between the different N2O sources (Kool et al. 2011) are here supposed to utilize initially in peatland research. Furthermore, peatlands could act as a source for N2O but it is unknown among which circumstances. A better comprehension of the N2O sources and sinks enables a specifically management for the reduction of N2O emissions.
