Abstract

Abstract

Since the industrial revolution,large amounts of CO₂ released by human activities into the atmosphere not only produce serious greenhouse effect,but also cause ocean acidification (OA). Reef-building corals are thought to the most sensitive to ocean acidification. Ocean acidification is predicted to impact the physiology of corals and reduce the calcification rates. In the present study,the calcification and photosynthesis capacity (F_v/F_m) of hermatypic coral Pocillopora damicornis was measured to study the physiological effect of OA by the simulation of further scenario of ocean acidification based on the gas exchange method. The experiment was conducted for 5 weeks in natural light with the seawater temperature controlled at 27.5℃ (±1℃) by the chiller. Two pH values (7.8 and 8.1,respectively) were set by pH regulation,which mediate the CO₂ gas into experimental seawater. The diurnal variation of pH during the experiment was observed,with the pH values varied from 7.69 to 7.91 for the OA treatment and from 7.99 to 8.29 for the control due to the metabolic process (mainly respiration from the organisms). The results showed that the calcification rate of P. damicornis ranged from 1.15%~2.09%·week^-1,and no significant difference was found in calcification and F_v/F_m between OA treatment and the control,indicating the low sensitivity of P. damicornis to OA. Compared to those previous publications,species-specific responses were further confirmed facing to OA. It is speculated that the tolerance of P. damicornis to OA may be due to the use of HCO₃^- in the light and up-regulation of pH in at their site of calcification. The capacity to up-regulate pH may be central to the resilience of P. damicornis to OA because the buffer capacity of pH can maintain relatively high the saturation of aragonite at their site of calcification and thus the calcification of corals at relatively low cost.
