      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. ...
    • Microbial community composition shapes enzyme patterns in topsoil and subsoil horizons along a latitudinal transect in Western Siberia 

      Schnecker, Jörg; Wild, Birgit; Takriti, Mounir; Eloy Alves, Ricardo J; Gentsch, Norman; Gittel, Antje; Hofer, Angelika; Klaus, Karoline; Knoltsch, Anna; Lashchinskiy, Nikolay; Mikutta, Robert; Richter, Andreas (Peer reviewed; Journal article, 2015-04)
      Soil horizons below 30 cm depth contain about 60% of the organic carbon stored in soils. Although insight into the physical and chemical stabilization of soil organic matter (SOM) and into microbial community composition ...
    • Microbial nitrogen dynamics in organic and mineral soil horizons along a latitudinal transect in western Siberia 

      Wild, Birgit; Schnecker, Jörg; Knoltsch, Anna; Takriti, Mounir; Mooshammer, Maria; Gentsch, Norman; Mikutta, Robert; Alves, Ricardo J. Eloy; Gittel, Antje; Lashchinskiy, Nikolay; Richter, Andreas (Peer reviewed; Journal article, 2015-05-12)
      Soil N availability is constrained by the breakdown of N-containing polymers such as proteins to oligopeptides and amino acids that can be taken up by plants and microorganisms. Excess N is released from microbial cells ...
    • 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 ...
