- unchanged
Signature 1
Source: Supplementary Table 6 and 7
Description: Differential abundance (FDR adjusted p_value <0.05) between subsistence patterns according to DESeq2 analysis. Positive values in the log2FoldChange indicate taxa enriched in the first subsistence method of the comparison, and negative values represent taxa enriched in the second one.
Abundance in Group 1: increased abundance in Foragers
