Fig. 2 Shannon diversity and Chao1 richness of bacterial (Figs.
2a and 2c) and fungal (Figs. 2b and 2d) communities in plantation stands
of different ages. Different upper and lowercase letters indicate
different levels among different ages and soil depth, respectively (n =
3, p < 0.05)
The α-diversity (represented by Shannon’s diversity and Chao1 richness)
of the soil bacteria community differed among 10-40 cm in 30 and 50
years plantations but not in 0-10 cm soil (Figs. 2a and 2c), and, the
diversity measurements such as the Shannon index and Chao1 richness
indicate that 0-10 cm has a higher α-diversity than 10-40 cm. However, a
major dissimilarity was observed among the fungal communities in the
soil microhabitat samples collected
from different stands (Figs. 2b and 2d), indicating that the fungal
communities were highly diverse in soil from different soil layers.
