Metan flukse og de funktionelle grupper af methanotrofer og methanogener i et ungt arktisk landskab på Disko Ø, Vestgrønland
Arctic soils are known to be important methane (CH4) consumers and sources. This study integrates in situ fluxes of CH4 between upland and wetland soils with potential rates of CH4 oxidation and production as well as abundance and diversity of the methanotrophs and methanogens measured with pyrosequ...

Arctic soils are known to be important methane (CH4) consumers and sources. This study integrates in situ fluxes of CH4 between upland and wetland soils with potential rates of CH4 oxidation and production as well as abundance and diversity of the methanotrophs and methanogens measured with pyrosequencing of 16S DNA and rRNA fragments in soil and permafrost layers. Here, the spatial patterns of in situ CH4 fluxes for a 2,000 years old Arctic landscape in West Greenland reveal similar CH4 uptake rates (-4 ± 0.3 lmol m-2 h-1) as in other Arctic sites, but lower CH4 emissions (14 ± 1.5 lmol m-2 h-1) at wetland sites compared to other Arctic wetlands. Potential CH4 oxidation was similar for upland and wetland soils, but the wetter soils produced more CH4 in active and permafrost layers. Accordingly, the abundance of methanogenic archaea was highest in wetland soils.
