Abundance of detoxification proteins between marine habitats. a) Comparison of the relative abundance of the detoxification proteins between the three major habitats open ocean (blue bars), coastal (red bars) and estuary (green bars). b) Comparison of relative abundance between non-polluted (blue) and polluted (red) sites. Bars indicate relative abundance in relation to the protein family abundance in the open ocean sites (a) or non-polluted sites (b), fixed to one, and only proteins that exhibited a significant difference in relative abundance between sites are displayed. Brackets indicate which comparisons that were significant; black brackets (p < 0.01) and grey brackets (p < 0.05).
