Fig 3. Box plots showing Chao1 richness and Shannon diversity of bacterial/archaeal and fungal communities affected by two soil depths (0–5 and 5–15 cm) and four sampling seasons (Winter 2016, Spring, Summer, and Fall 2017).

Sequence depths were 10000 for 16S and 5000 for ITS. Asterisks indicate significant difference at α = 0.05 between two soil depths or among four sampling seasons.
