Fig. 4From: Bacterial communities in surface and basal ice of a glacier terminus in the headwaters of Yangtze River on the Qinghai–Tibet PlateauTaxonomic properties of bacterial communities in surface ice (SI) and basal ice (BI). a Alpha diversity. b Non-metric multidimensional scaling based on the relative abundance of all OTUs. c Hierarchical cluster dendrogram for the 59 core OTUs in both basal ice and surface ice based on Bray–Curtis dissimilarity. The colors in the heatmap illustrate the relative abundance of each OTU per sampling site. d Bacterial community composition shown at the phylum levelBack to article page
