| 英文摘要 | Although negative responses of tropical calcifying organisms to ocean acidification have been widely reported, the modulating potential of irradiance combined with elevated pCO(2) has not been well studied. In this study, the interactive effects of elevated pCO(2) and irradiance availability on the physiology of calcifying macroalgae Halimeda cylindracea and Halimeda lacunalis were investigated using a fully factorial, 28-day aquaria coupling experiment. The results of the present study demonstrate that elevated pCO(2) negatively influences growth, photosynthesis, calcification and other physiological processes of both Halimeda species. However, these ne-gative effects could be mitigated to some extent by increased irradiance availability. Specific growth rate (SGR), net calcification rates (G(net)) and maximum quantum yield (F-v/F-m) decreased significantly by 6.84%-86.70%, 51.78%-62.29% and 2.37%-28.91% in elevated pCO(2) treatments. However, SGR, G(net) and F-v/F-m increased by 3.39%-84.78%, 29.61%-40.68% and 1.68%-6.92% in high irradiance conditions, respectively. Chl-a in elevated pCO(2) treatments was 7.75%-61.25% lower than ambient pCO(2) conditions, while the carotenoid content in-creased by 12.12%-57.45% in low irradiance conditions from day 20-28. Malondialdehyde (MDA) content was higher in elevated pCO(2) treatments. However, there was also a two- to four-fold increase in proline content in elevated pCO(2) treatments. Tissue total organic carbon (TCorg) and nitrogen (TN) were positively correlated to CO2 enrichment. The results of the current study suggested that elevated pCO(2) negatively influenced the phy-siological responses of Halimeda, while increased irradiance availability may enhance the metabolic performance in response to ocean acidification. |
