Methylotrophy in the Mire: direct and indirect routes for methane production in thawing permafrost

J. B. Ellenbogen, M. A. Borton, B. B. McGivern, D. R. Cronin, D. W. Hoyt, V. Freire-Zapata, C. K. McCalley, R. K. Varner, P. M. Crill, R. A. Wehr, J. P. Chanton, B. J. Woodcroft, M. M. Tfaily, G. W. Tyson, V. I. Rich, K. C. Wrighton

This study identifies methylotrophic methanogenesis and bacterial methylotrophy as significant contributors to methane production in thawing permafrost.

Diverse Arctic lake sediment microbiota shape methane emission temperature sensitivity

J. B. Emerson, R. K. Varner, M. Wik, D. H. Parks, R. B. Neumann, J. E. Johnson, C. M. Singleton, B. J. Woodcroft, R. Tollerson, A. Owusu-Dommey, M. Binder, N. L. Freitas, P. M. Crill, S. R. Saleska, G. W. Tyson, V. I. Rich

This study shows that spatial variations in sediment microbiota influence methane emission temperature sensitivity in Arctic lakes.

Evidence for non-methanogenic metabolisms in globally distributed archaeal clades basal to the Methanomassiliicoccales

L. A. Zinke, P. N. Evans, A. Schroeder, D. H. Parks, R. K. Varner, V. Rich, G. Tyson, J. B. Emerson

This study shows that Thermoplasmata archaea lack methanogenesis genes, suggesting methanogenesis was laterally acquired by Methanomassiliicoccales, and identifies new Thermoplasmata lineages with diverse metabolic capabilities.
