Heatmap of fourth-root transformed relative abundance of 62 zOTUs identified as significantly different between dolphins. The microbial communities of blow across individual dolphins were shown to be significantly different. The blow samples per dolphin (columns) are listed in chronological order. ‘Gemma’, ‘Howie’, ‘Nudgee’ and ‘Stella’ were marked with an asterisk to indicate their antimicrobial treatment. The position of the asterisk in the diagram indicates the timing of their treatment
