Web1 nov. 2012 · Methane can be generated in situ by methanogenic archaea (a group belonging to the Euryarchaeota) under anaerobic conditions, but it can also be oxidized by methanotrophs such as methane-oxidizing bacteria (MOB), making tundra environments act as a methane sink (Whalen et al ., 1990; Callaghan et al ., 2005; Wagner & Liebner, 2009 ). This graphic depicts the flow of methane from natural and anthropogenic sources into the atmosphere as well as the sinks that capture, convert, or store methane. Any process that results in the production of methane and its release into the atmosphere can be considered a "source".
