Effect of Freeze-Thaw on a Midtemperate Soil Bacterial Community and the Correlation Network of Its Members

Figure 1

Comparison of the bacterial community structures between different treatments in three tests. Principal coordinate analysis (PCoA) by weighted-UniFrac dissimilarity matrices for the bacterial communities based on OTUs in the Amplitude test (a), Frequency test (b), and SWC test (c). Symbols are colored by different treatments, and ellipses were drawn for each test with a confidence limit of 0.99.
