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

Figure 5

A partial correlation network of the main OTUs (circles, >0.1% of the relative abundance) and bulk microbial properties (squares) across all soil samples. Different colors indicate different phyla. Solid and dashed lines indicate the positive and negative correlations, respectively. PA: protease activity; MBN: microbial biomass nitrogen; NRA: nitrate reductase activity.
