Bacterial composition and diversity in olive flounder across varying temperature conditions. (A) Phylogenetic trees generated by GraPhlAn, illustrating the bacterial composition from the phylum to genus level. Red bars indicate taxa with a bacterial abundance greater than 0.5%, blue triangles represent taxa with an abundance less than 0.5%, and gray bars display a heat map visualization across different samples, the value present the percentage of relative abundance form 0–1. (B) Bar chart showing the relative abundance of bacterial classes
