FIGURE 4.

Map depicting the distribution of jellyfish species identified by eDNA metabarcoding based on 16S rDNA sequences in YSB. (a–c) July distribution of jellyfish species in the surface seawater, bottom seawater and sediment, respectively; (d–f) August distribution of jellyfish species in the surface seawater, bottom seawater and sediment, respectively. Circle charts of 48 sequenced samples were plotted to reflect the composition of the medusozoan community at corresponding stations. Unannotated blue rings indicate that Aurelia coerulea was the only jellyfish species at that station. If other jellyfish species were identified at a certain station, a specific explanation is given next to the circle, with the relative abundance of the species in parentheses. The number of reads was the total number of medusozoan sequences per station.
