Figure 1From: Comparative analysis of the human saliva microbiome from different climate zones: Alaska, Germany, and Africa Relative abundance of predominant genera (>0.5%) among native Alaskans, Germans and Africans. The phylogenetic tree was calculated with representative full-length sequences, and the scale bar represents evolutionary distance (10 substitutions per 100 nucleotides). Bacterial phyla are indicated by different colors; the vertical bars on the right of each plot indicate the relative abundance of each phylum, as designated by the colors.Back to article page
