a
Physiochemical and nutrient variables that did not have any significant correlations to bacterial taxa are not included in this table.
b
Information in parentheses in the top row indicates units of concentration per gram of feces.
c
Values represent p-values of the correlation analysis, with the significant correlations (p < 0.05) bolded. The R2 values for the significant correlations are provided in italics within parentheses below the p-value.
