Effects of soil organic matter properties and microbial community composition on enzyme activities in cryoturbated arctic soils
Schnecker, Jörg; Wild, Birgit; Hofhansl, Florian; Alves, Ricardo J. Eloy; Bárta, Jiří; Čapek, Petr; Fuchslueger, Lucia; Gentsch, Norman; Gittel, Antje; Guggenberger, Georg; Hofer, Angelika; Kienzl, Sandra; Knoltsch, Anna; Lashchinskiy, Nikolay; Mikutta, Robert; Šantrůčková, Hana; Shibistova, Olga; Takriti, Mounir; Urich, Tim; Weltin, Georg; Richter, Andreas (Peer reviewed; Journal article, 2014-04-04)Enzyme-mediated decomposition of soil organic matter (SOM) is controlled, amongst other factors, by organic matter properties and by the microbial decomposer community present. Since microbial community composition and SOM ... -
Input of easily available organic C and N stimulates microbial decomposition of soil organic matter in arctic permafrost soil
Wild, Birgit; Schnecker, Jörg; Alves, Ricardo J. Eloy; Barsukov, Pavel; Bárta, Jiří; Čapek, Petr; Gentsch, Norman; Gittel, Antje; Guggenberger, Georg; Lashchinskiy, Nikolay; Mikutta, Robert; Rusalimova, Olga; Šantrůčková, Hana; Shibistova, Olga; Urich, Tim; Watzka, Margarete; Zrazhevskaya, Galina; Richter, Andreas (Peer reviewed; Journal article, 2014-08)Rising temperatures in the Arctic can affect soil organic matter (SOM) decomposition directly and indirectly, by increasing plant primary production and thus the allocation of plant-derived organic compounds into the soil. ... -
Lignin Preservation and Microbial Carbohydrate Metabolism in Permafrost Soils
Dao, Thao Thi; Mikutta, Robert; Sauheitl, Leopold; Gentsch, Norman; Shibistova, Olga; Wild, Birgit; Schnecker, Jörg; Bárta, Jiří; Čapek, Petr; Gittel, Antje; Lashchinskiy, Nikolay; Urich, Tim; Šantrůčková, Hana; Richter, Andreas; Guggenberger, Georg (Journal article; Peer reviewed, 2022)Permafrost-affected soils in the northern circumpolar region store more than 1,000 Pg soil organic carbon (OC), and are strongly vulnerable to climatic warming. However, the extent to which changing soil environmental ... -
Nitrogen dynamics in Turbic Cryosols from Siberia and Greenland
Wild, Birgit; Schnecker, Jörg; Bárta, Jiří; Čapek, Petr; Guggenberger, Georg; Hofhansl, Florian; Kaiser, Christina; Lashchinsky, Nikolaj; Mikutta, Robert; Mooshammer, Maria; Šantrůčková, Hana; Shibistova, Olga; Urich, Tim; Zimov, Sergey A.; Richter, Andreas (Peer reviewed; Journal article, 2013-12)Turbic Cryosols (permafrost soils characterized by cryoturbation, i.e., by mixing of soil layers due to freezing and thawing) are widespread across the Arctic, and contain large amounts of poorly decomposed organic material ... -
Site- and horizon-specific patterns of microbial community structure and enzyme activities in permafrost-affected soils of Greenland
Gittel, Antje; Barta, Jiri; Kohoutova, Iva; Schnecker, Jörg; Wild, Birgit; Čapek, Petr; Kaiser, Christina; Torsvik, Vigdis Lid; Richter, Andreas; Schleper, Christa Maria; Urich, Tim (Peer reviewed; Journal article, 2014-10-16)Permafrost-affected soils in the Northern latitudes store huge amounts of organic carbon (OC) that is prone to microbial degradation and subsequent release of greenhouse gasses to the atmosphere. In Greenland, the consequences ...
