Figure 3

Western Arctic Ocean bacterial community characteristics: (a) clustering of samples at the operational taxonomic unit (OTU) level based on the Bray-Curtis distance (SC, FZ, and NC indicate the regional groups as defined in Fig. 1); (b) distance based redundancy analysis (dbRDA) ordination diagram of bacterial communities based on OTU with related physical and biogeochemical factors including latitude (Lat), temperature (T), salinity (S), dissolved inorganic nitrogen (DIN), phosphate (PO4), silicate (SiO2), and Chl-a, represented by arrows; (c) relative abundance of bacterial community composition at the class level; and (d) hierarchical heatmap showing the relative abundance at the genus level. Color code indicates the relative abundance, ranging from blue (low abundance) to red (high abundance). For (c,d) represented taxa occurred at >1% abundance in at least one sample.
