However, the related plant-microbe interactions are still poorly understood. We aimed to link the recovery of the organisms responsible for CH4 turnover, the methanogens and the methanotrophs, to the re-vegetation related compositional changes of three functional plant types (Sphagna, sedges and shrubs). In peat layers, the Sphagnum coverage was the most influential factor for the activity, abundance and community structures of both these microbial groups, demonstrating a succession pattern towards a pristine stage. Analysis of mcrA and pmoA genes revealed Methanoregulaceae and Methylocystis as the most dominant methanogens and methanotrophs, respectively. The relatively fast recovery of both CH4 production and oxidation in the peat layers supports earlier flux based results from these same fen-type peatland sites. In contrast to peat, CH4 oxidation in living Sphagnum mosses appeared to be independent of vegetation succession as CH4 oxidation potential was similar throughout the succession stages. This indicated that Sphagnum may be a valuable CH4 biofilter especially in the early re-vegetation stages when the oxidation in the peat has not yet recovered. Therefore, we recommend Sphagnum transplantation as a tool for climate friendly peatland restoration with faster recovery of the carbon sink function and altered CH4 emissions.", "keywords": ["0301 basic medicine", "570", "0303 health sciences", "Aitoneva", "peat extraction", "ta1172", "ta1183", "Methanogenic archaea", "plant functional types", "15.

Undisturbed peatlands are effective carbon sinks and provide a variety of ecosystem services. However, anthropogenic disturbances, especially land drainage, strongly alter peat soil properties and jeopardize the benefits of peatlands. The effects of disturbances should therefore be assessed and predicted. To support accurate modeling, this study determined the physical and hydraulic properties of intact and disturbed peat samples collected from 59 sites (in total 3,073 samples) in Finland and Norway. The bulk density (BD), porosity, and specific yield (Sy) values obtained indicated that the top layer (0\uffe2\uff80\uff9330\uffc2\uffa0cm depth) at agricultural and peat extraction sites was most affected by land use change. The BD in the top layer at agricultural, peat extraction, and forestry sites was 441%, 140%, and 92% higher, respectively, than that of intact peatlands. Porosity decreased with increased BD, but not linearly. Agricultural and peat extraction sites had the lowest saturated hydraulic conductivity, Sy, and porosity, and the highest BD of the land use options studied. The van Genuchten\uffe2\uff80\uff90Mualem (vGM) soil water retention curve (SWRC) and hydraulic conductivity (K) models proved to be applicable for the peat soils tested, providing values of SWRC, K, and vGM\uffe2\uff80\uff90parameters (\uffce\uffb1 and n) for peat layers (top, middle and bottom) under different land uses. A decrease in peat soil water content of \uffe2\uff89\uffa510% reduced the unsaturated K values by two orders of magnitude. This unique data set can be used to improve hydrological modeling in peat\uffe2\uff80\uff90dominated catchments and for fuller integration of peat soils into large\uffe2\uff80\uff90scale hydrological models.Undisturbed peatlands are effective carbon sinks and provide a variety of ecosystem services.
