Figure 4.
Gross productivity (PG) versus calcification (G) and zooxanthellae percentage change for A. palmata (outer-reef, low-variance (LV) habitat), P. astreoides (seagrass, high-variance (HV) habitat) and P. astreoides (LV) from Little Cayman, Cayman Islands, BWI. (a) Percentage change in PG versus G and (b) percentage change in PG plotted against the per cent change in zooxanthellae. Relative percentage change (±s.e.) was determined by averaging the experimental replicates per treatment (n = 5) and standardizing by the control at the end of the experiment (te).
