Figure 5.

Abundance of coral–algal interactions across a range of human impact and coral cover. (a) The average per cent of coral colony edge interacting with the indicated type of algae at the seven surveyed sites east to west across Curacao; the remainder of the perimeter not interacting with algae included interactions with sand, sponges and other corals. Numbers above bars indicate the number of coral colonies observed at each site. (b) Relationship between benthic coral coverage and the average per cent of each colony interacting with crustose coralline algae (CCA) at each site (r² = 0.66; p = 0.026). (a) Brown, Cyanobacteria; green, turf; yellow, Halimeda; red, Dictyota; blue, CCA.
