Analysis of alpha diversity of gut microbiota
The results of alpha diversity analysis based on the phylum level using
the Wilcoxon rank sum test showed that the Ace richness estimator in the
autumn group (P =0.023<0.05) was significantly higher
than that in the spring group (Figure 2A). However, the Shannon–Wiener
diversity index in the spring group (P =0.029<0.05) was
significantly higher than in the autumn group (Figure 2B). At the family
level, the Ace (P =0.029<0.05) and Shannon
(P =0.029<0.05) indices in the autumn group were
significantly higher than those in the spring group (Figure 2C, D).
