Fig. 2From: Bacterial communities in surface and basal ice of a glacier terminus in the headwaters of Yangtze River on the Qinghai–Tibet Plateaua Venn diagram showing the shared and unique OTUs between surface ice and basal ice. b–d Flower plot diagram showing core and unique OTUs across all samples in basal ice, surface ice, and both. The central circle shows the number of OTUs common to all samples while the petals show the number of OTUs in addition to the core set, as well as the number of OTUs unique to each sample (in brackets)Back to article page
