| Abstract | Net primary productivity and respiration of Acropora palmata (Lamarck) and of the algal turf and macroscopic algae growing on dead coral from Tague Bay Reef, St. Croix, were measured inside an experimental chamber. Mean productivity rates differed significantly, with macroscopic algae producing more oxygen than algal turf and turf production exceeding that of the live coral. Mean respiration of macroscopic algae was significantly higher than that for A. palmata and for algal turf, while A. palmata respiration significantly exceeded turf respiration. Net primary productivity for macroscopic algae ranged from 1.16 to 8.98 gO2 · m−2 · h−1 (x = 3.13 ± 2.26SD, n = 31), and respiration varied from 0.19 to 0.64 (x = 0.44 ± 0.13SD, n = 18). Net primary production of A. palmata branches ranged from 0.15 to 0.54 gO2· m−2· h−1 (x = 0.30 ± 0.10SD, n = 27), while respiration ranged from 0.22 to 0.53 gO2 · m−2 · h−1 (x = 0.32 ± 0.08Sd, n = 12). Net primary productivity and respiration of algal turf was 0.23 to 0.93 gO2· m−2· h−1 (x = 0.50 ± 0.16SD, n = 28) and 0.13 to 0.40 (x = 0.23 ± 0.08SD. n = 16). respectively. Although less conspicuous in some reef areas than live or turf-covered A. palmala, macroscopic algae may represent a major part of the total primary productivity of some coral reefs. |
