Fig. 5

Venn diagrams illustrating shared and unique soil bacteria and fungi under N addition. Figure (a–c) represent the number of OTUs of soil bacteria in different soil layers under N addition, whereas Figure (d–f) represent the number of OTUs of soil fungi in different soil layers under N addition. The acronym of “B” and “F” in the figure represent bacteria and fungi, respectively; the acronym of “1”, “2”, and “3” represent soil depths of 0 ~ 5 cm, 5 ~ 10 cm, and 10 ~ 20 cm. CK, LN, MN, and HN represent four N addition levels, respectively.
