Spearman correlation analysis between the relative read abundance of dominant jellyfish taxa and environmental factors (a) in all 98 eDNA samples, and (b–d) in samples taken from the surface, middle, and bottom layers, respectively. Note A network heatmap of correlations between the relative read abundance of dominant jellyfish taxa and environmental factors. The color of the blocks in the right heatmap indicates a positive or negative correlation coefficient between different environmental factors, and the size of the blocks indicates the absolute value of correlation coefficients. The thickness of the lines indicates the strength of the correlations between the relative read abundances of the three dominant jellyfish species and environmental factors (Mental R), and the color of the lines indicates the degree of significance (Mental P)
