a Taxonomic composition of the microbial community across three glacial ecosystems. b Taxonomic composition of the microbial community across seven habitats. The phylum Proteobacteria was divided into class levels. Phylum that sums of relative abundance below top 9 merged as Others. Sample abbreviation as fellows: SupC supraglacial cryoconite, SupS supraglacial stream, SubM subglacial meltwater, SubS subglacial sediment, ProW proglacial lake water, ProS proglacial lake sediment.
