Figures & Tables

Rarefaction curves for operational taxonomic units (OTUs) from the Seonginbong, Dongdo, and Seodo samples. (a) Shannon, (b) Simpson, and (c) Chao1 indexes. (d) UPGMA tree based on the community structures of Seonginbong, Dongdo, and Seodo. Seonginbong (red line), Dongdo (blue line), and Seodo (orange line).

Taxonomic composition of the eukaryotic microbial phyla on Seonginbong, Dongdo, and Seodo.

Taxonomic composition of the microalgal classes on Seonginbong, Dongdo, and Seodo.

Molecular phylogenetic analysis using a maximum likelihood (ML) tree. The boundary between phyla is marked with a yellow box, and the boundaries between classes are marked with purple boxes. Five classes are displayed about the species names in the phylogenetic tree. The dominant species in each sample is marked with a colored box (Seonginbong: red; Dongdo: blue; Seodo: green). The class of each group is presented at the edge (Bacillariophyceae; red, Coscinodiscophyceae; yellow, Chlorophyceae; blue, Trebouxiophyceae; green and Ulvophyceae; purple).
