Fig. 1. Abiotic variables: (a) pH, (b) water temperature, and
(c) salinity, and biotic variables: (d) abundance, (e) Shannon’s
diversity index, and (f) species richness.
Fig. 2. Hierarchical cluster analysis (UPGMA) of diatom
communities based on (a) Bray–Curtis similarity, and (b) biogeographic
zonation in the Yellow Sea (YS), South Sea (SS), and East Sea (ES) of
Korea during winter.
Fig. 3. Heatmap graph on fourth root transformed abundance data
for indicator species in the Yellow Sea (YS), South Sea (SS), Southern
East Sea (SES), and Northern East Sea (NES) ecoregions. Colors for
species denote the selected indicator species for each ecoregion: YS
(yellow), SS (green), SES (orange), and NES (blue).
