CREST – Classification Resources for Environmental Sequence Tags
Lanzén, Anders; Jørgensen, Steffen Leth; Huson, Daniel H.; Gorfer, Markus; Grindhaug, Svenn Helge; Jonassen, Inge; Øvreås, Lise; Urich, Tim (Peer reviewed; Journal article, 2012-11-08)Sequencing of taxonomic or phylogenetic markers is becoming a fast and efficient method for studying environmental microbial communities. This has resulted in a steadily growing collection of marker sequences, most notably ... -
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 ... -
Functional analysis of metagenomes and metatranscriptomes using SEED and KEGG
Mitra, Suparna; Rupek, Paul; Richter, Daniel C.; Urich, Tim; Gilbert, Jack A.; Meyer, Folker; Wilke, Andreas; Huson, Daniel H. (Peer reviewed; Journal article, 2011-02-15)Background: Metagenomics is the study of microbial organisms using sequencing applied directly to environmental samples. Technological advances in next-generation sequencing methods are fueling a rapid increase in the ... -
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 ... -
Simultaneous Assessment of Soil Microbial Community Structure and Function through Analysis of the Meta-Transcriptome
Urich, Tim; Lanzén, Anders; Qi, Ji; Huson, Daniel H.; Schleper, Christa Maria; Schuster, Stephan C. (Peer reviewed; Journal article, 2008-06-25)Background: Soil ecosystems harbor the most complex prokaryotic and eukaryotic microbial communities on Earth. Experimental approaches studying these systems usually focus on either the soil community’s taxonomic structure ... -
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 ...
