| 摘 要： | 通过Alkalinity anomaly technique测定了栉孔扇贝Chlamys farreri在不同酸度条件下的钙化率和呼吸率,发现栉孔扇贝的钙化和呼吸活动受酸化影响显著,均随着酸化的加剧出现了明显下降。当pH降低到7.9时,栉孔扇贝的钙化率将会下降33%左右;当pH降到7.3左右时,栉孔扇贝的钙化率将趋近于0,栉孔扇贝无法产生贝壳,而此时栉孔扇贝碳呼吸率(RC)与耗氧率(RO)也分别下降了14%和11%。随着酸化的加剧,栉孔扇贝的能量代谢方式也会发生改变。这些变化都可能影响到栉孔扇贝的生存。

| Abstract: | The ocean is becoming more and more acidic in unprecedented speed in the history of the earth resulting from emissions of CO2 by human activities.The survival state of calcification organisms such as shellfish may be threatened by marine acidification.So the calcification rate and respiratory rate of Chlamys farreri were investigated using the alkalinity anomaly technique at different pH.It was found that calcification rate and respiration rate decreased significantly as pH declined.Calcification rate decre... |
