3.2. Assemblages
3.2.1. Regional differences
Regional differences in cover, abundances and richness of some of the assemblages were pronounced (Table 1, Figs. 3 and 4). WT reefs were predominantly covered in algae and had low hard coral and octocoral cover. In WT, total algal cover was almost twice as high as PC, mostly due to differences in turfing algae, whereas cover of macroalgae and coralline algae were similar. Hard coral cover was less than a third, and octocoral cover was about half as high as in PC, whereas the cover of dead standing corals was 4.5 times higher in WT than in PC. Abundances of fish in WT were about a third of those in PC.
