The bacterial Shannon index did not show an obvious trend along the altitude gradient and was only significantly different from other altitudes at 340 m ( p < 0.05).
The bacterial Shannon index did not show an obvious trend along the altitude gradient and was only significantly different from other altitudes at 340 m ( p < 0.05).
However, the results showed that the fungal Shannon index showed a trend of first increasing and then decreasing, with significant differences between the Shannon index at 530 m, 850 m, and 1400 m ( p < 0.05).
However, previous studies have reported a decreasing trend or no significant changes in fungal community diversity with increasing altitude [ 43 ].
