Diversity and Distribution of Archaea Community along a Stratigraphic Permafrost Profile from Qinghai-Tibetan Plateau, China

Figure 2

Frequency of individual types (OTU) and relative depth-dependent distribution of groups of the archaea from the stratigraphic permafrost profile based on the gene clone libraries. Green segments indicate OTUs belonging to unclassified Euryarchaeota, blue segments indicate OTUs belonging to Group 1.3b/MCG-A, yellow segments indicate OTUs belonging to Methanosaetaceae, red segments indicate OTUs belonging to Methanosarcinaceae, and pink segments indicate OTUs belonging to Methanomicrobiales.
