Fig. 3From: Gut microbiota is associated with the effect of photoperiod on seasonal breeding in male Brandt’s voles (Lasiopodomys brandtii)Fecal microbiota in the LD and SD groups and their relationship with reproductive phenotypes. a Richness diversity (means ± SEM) of bacterial communities across groups. b Constrained principal coordinate analysis (CPCoA) based on the Bray-Curtis dissimilarity matrix at the amplicon sequence variants (ASVs) level in different groups. c Heatmap showing Spearman correlation between ASVs and serum hormone levels or gene expression in the hypothalamus and testis. Only the ASVs that had a highly significant difference between photoperiod treatments (P < 0.01) were labeled with asterisks: **P < 0.01 and ***P < 0.001Back to article page
