Figure 2

Correspondence analysis plot for each taxon group. Red points are the positions of individual taxa with respect to sites. Where predictor variables were significantly associated with pattern across the sites, these are added to the plots as lines, with direction and magnitude from the origin indicating the influence of the variable. Site labels; (a) Cawsand Bay, (b) Inner Breakwater, (c) Jennycliff Bay, (d) Mallard Shoal, (e) West Mud, (f) St. John’s Lake, (g) Sutton Lock. Variable labels; S1) sediment PC score on axis 1, S2) sediment PC2, H1) hydrocarbon PC1, H2) hydrocarbon PC2, E2) environmental PC2, B1) bioturbation PC1, B2) bioturbation PC2 and BPc) community bioturbation potential index.
