Fig. 6From: Japanese quail (Coturnix japonica) as a novel model to study the relationship between the avian microbiome and microbial endocrinology-based host-microbe interactionsAssociations between cecal bacterial relative abundances and chemical levels in the jejunum. CCA of microbiota composition regressed on chemical concentrations in the Jejunum. Filled circles represent samples while red crosses represent bacterial taxa (genus level) with the top 5% of taxa which best fit the axes being indicated by name. Chemical vectors point to the direction of taxa with which they exhibit the strongest association with while their magnitude indicates the strength of the variable in explaining the bacterial dispersion observed. The canonical variates explain 50.3% and 33.7% of the total explainable variance in the first and second axis, respectively. 5-HIAA 5-hydroxyindoleacetic acid, 5-HT 5-hydroxytryptamine, DOPAC 3,4-dihydroxyphenylacetic acid, HVA homovanillic acid, UNKN #1 Unknown #1, UNKN #2 Unknown #2Back to article page
