Fig. 1From: Metagenomics reveals global-scale contrasts in nitrogen cycling and cyanobacterial light-harvesting mechanisms in glacier cryoconiteComparison of bacterial community structures among cryoconite samples. a Bacterial taxonomic composition (mainly classified at the family level). b PCA based on the 16S rRNA gene abundance of bacterial families. SH, Southern Hemisphere. c Abundance and taxonomic affiliation of cyanobacterial 16S rRNA genes. Abundance was normalized to the total read abundance of 16S rRNA genes in each sample (adjusted to 1,000,000). d Principal component analysis based on the read abundance of KEGG-annotated genesBack to article page
