Journal ArticleDOI
An active atmospheric methane sink in high Arctic mineral cryosols
Maggie C. Y. Lau,B. T. Stackhouse,Alice C. Layton,Archana Chauhan,Tatiana A. Vishnivetskaya,Karuna Chourey,Jennifer Ronholm,Nadia C. S. Mykytczuk,Philip C. Bennett,Guillaume Lamarche-Gagnon,N. Burton,Wayne H. Pollard,Christopher R. Omelon,David Medvigy,Robert L. Hettich,Susan M. Pfiffner,Lyle G. Whyte,Tullis C. Onstott +17 more
TL;DR: It is demonstrated that acidic mineral cryosols are a previously unrecognized potential of CH4 sink that requires further investigation to determine its potential impact on larger scales, and calls attention to the poleward distribution of atmMOB.
Book ChapterDOI
Bacteria in Permafrost
David Gilichinsky,Tatiana A. Vishnivetskaya,Mayya Petrova,E. V. Spirina,Vladimir Mamykin,Elizaveta Rivkina +5 more
TL;DR: Significant numbers of viable ancient microorganisms are known to be present within the permafrost as mentioned in this paper, and they have been isolated in both polar regions from the cores up to 400 m deep and ground temperatures of -27 C.
Journal ArticleDOI
Metagenomic analyses of the late Pleistocene permafrost – additional tools for reconstruction of environmental conditions
Elizaveta Rivkina,Lada E. Petrovskaya,Tatiana A. Vishnivetskaya,Tatiana A. Vishnivetskaya,Kirill Krivushin,Lyubov Shmakova,Maria N. Tutukina,Arthur J. Meyers,Fyodor A. Kondrashov,Fyodor A. Kondrashov +9 more
TL;DR: A comparative analysis of the metagenomes from two 30,000-year-old permafrost samples, one of lake-alluvial origin and the other from late Pleistocene Ice Complex sediments, revealed significant differences within microbial communities.
Journal ArticleDOI
Environmental proteomics reveals early microbial community responses to biostimulation at a uranium- and nitrate-contaminated site
Karuna Chourey,Silke Nissen,Silke Nissen,Tatiana A. Vishnivetskaya,Manesh Shah,Susan M. Pfiffner,Robert L. Hettich,Robert L. Hettich,Frank E. Löffler +8 more
TL;DR: Environmental metaproteomics identified microbial community responses to biostimulation and elucidated active pathways demonstrating the value of this technique as a monitoring tool and for complementing nucleic acid‐based approaches.
Journal ArticleDOI
Microbial Communities in Subpermafrost Saline Fracture Water at the Lupin Au Mine, Nunavut, Canada
Tullis C. Onstott,Daniel J. McGown,Corien Bakermans,Timo Ruskeeniemi,Lasse Ahonen,Jon Telling,Bruno Soffientino,Susan M. Pfiffner,Barbara Sherwood-Lollar,Shaun K. Frape,Randy L. Stotler,Elizabeth J. Johnson,Tatiana A. Vishnivetskaya,Tatiana A. Vishnivetskaya,Randi K. Rothmel,Lisa M. Pratt +15 more
TL;DR: The absence of methanogens from this subsurface ecosystem is somewhat surprising, and may be attributable to an energy bottleneck that restricts their migration from surface permafrost deposits where they are frequently reported.
