Their archaeal communities were dominated by Euryarchaeota, specifically taxa in the methanogenic orders Methanomicrobiales and Methanosarcinales, indicating a potentially active community of planktonic methanogens.

Permafrost thaw lakes and ponds are among the most abundant freshwater ecosystems in the circumpolar North 11but studies of archaeal communities in these environments to date have focused on pond sediments in the High Arctic 12 and wetland soils in the Subarctic 13while the presence, diversity, and substrate preferences of methanogens in the water column plankton have not been explored.
After each randomization round, the number of hot spots was counted. Ecoscience 18— A phylogenetic tree was constructed with these OTUs and closest matches in Genbank.
These results indicate the widespread occurrence of planktonic, methane-producing Archaea in thaw ponds, with environmental selection of taxa according to permafrost landscape type.
