Atmospheric methane oxidizers are present and active in Canadian high Arctic soils
The melting of permafrost and the associated potential for methane emissions to the atmosphere are major concerns in the context of global warming. However, soils can also represent a significant sink for methane through the activity of methane oxidizing bacteria (MOB). In this study, we looked at t...
