Fig. 3From: Effects of permafrost collapse on soil bacterial communities in a wet meadow on the northern Qinghai-Tibetan PlateauDensity of total soil carbon (TC) (a), total nitrogen (TN) (b), soil moisture content (c) and pH (d) in different layers for the three stages of permafrost collapse. TC density at 0–10 cm, soil moisture content at all the samples in collapsing areas were significantly lower than those of control and subsided areas (**p < 0.01)Back to article page
