  bibo_abstract:
  - Rewetting of long-term drained fens often results in the formation of eutrophic
    shallow lakes with an average water depth of less than 1 m. This is accompanied
    by a fast vegetation shift from cultivated grasses via submerged hydrophytes to
    helophytes. As a result of rapid plant dying and decomposition, these systems
    are highly dynamic wetlands characterised by a high mobilisation of nutrients
    and elevated emissions of CO2 and CH4. However, the impact of specific plant species
    on these phenomena is not clear. Therefore we investigated the CO2 and CH4 production
    due to the subaqueous decomposition of shoot biomass of five selected plant species
    which represent different rewetting stages (Phalaris arundinacea, Ceratophyllum
    demersum, Typha latifolia, Phragmites australis and Carex riparia) during a 154
    day mesocosm study. Beside continuous gas flux measurements, we performed bulk
    chemical analysis of plant tissue, including carbon, nitrogen, phosphorus and
    plant polymer dynamics. Plant-specific mass losses after 154 days ranged from
    25% (P. australis) to 64% (C. demersum). Substantial differences were found for
    the CH4 production with highest values from decomposing C. demersum (0.4 g CH4
    kg−1 dry mass day) that were about 70 times higher than CH4 production from C.
    riparia. Thus, we found a strong divergence between mass loss of the litter and
    methane production during decomposition. If C. demersum as a hydrophyte is included
    in the statistical analysis solely nutrient contents (nitrogen and phosphorus)
    explain varying greenhouse gas production of the different plant species while
    lignin and polyphenols demonstrate no significant impact at all. Taking data of
    annual biomass production as important carbon source for methanogens into account,
    high CH4 emissions can be expected to last several decades as long as inundated
    and nutrient-rich conditions prevail. Different restoration measures like water
    level control, biomass extraction and top soil removal are discussed in the context
    of mitigation of CH4 emissions from rewetted fens.@eng
