Fig. 2From: Effects of permafrost collapse on soil bacterial communities in a wet meadow on the northern Qinghai-Tibetan PlateauRelative abundance of proteobacteria (a), acidobacteria (b), bacteroidetes (c), and chloroflexi (d) for the three stages of permafrost collapse. The significant differences among the three samples were indicated (*p < 0.05, **p < 0.01)Back to article page
