Fig. 4

Heatmap of the abundances of the top 20 genera of archaea in the three peatlands. All data were normalized to obtain differentiation values. Different colors show the differences in the archaeal abundances in different peat samples. Red and purple colors represent relatively high and low abundances of the archaeal community, respectively. Bars with different colors at the top of the heatmap indicate different locations of peat samples. Specific locations and peat layers (cm) are reported on the x-axis. R, T, and H denote Ruokeba, Taishanmiao, and Hani, respectively
