Fig. 5From: Bacterial communities in surface and basal ice of a glacier terminus in the headwaters of Yangtze River on the Qinghai–Tibet PlateauFunctional differences between bacterial communities in surface ice and basal ice. a Non-metric multidimensional scaling based on the relative abundance of all KOs. b KEGG categories at level 1. c KEGG categories at level 2. The differences were assessed using Wilcoxon rank-sum test with “*” and “**” represent p < 0.05 and p < 0.01, respectivelyBack to article page
