Abstract
Data on calcification rate of coral and crustose coralline algae were used to test the proton flux model of calcification. There was a significant correlation between calcification (G) and the ratio of dissolved inorganic carbon (DIC) to proton concentration ([DIC] : [H(+)] ratio). The ratio is tightly correlated with [CO3(2-)] and with aragonite saturation state (Ωa). An argument is presented that correlation does not prove cause and effect, and that Ωa and [CO3(2-)] have no basic physiological meaning on coral reefs other than a correlation with [DIC] : [H(+)] ratio, which is the driver of G.
摘要
珊瑚和有孔虫藻的钙化率数据被用来检验钙化的质子流模型。钙化（G）与溶解无机碳（DIC）与质子浓度的比值([DIC]：[H(+)] 比值)之间存在显著的相关性。该比值与[CO3(2-)]和霰石饱和度（Ωa）紧密相关。有人认为，相关性并不能证明因果关系，并且除了与[DIC]：[H(+)] 比值相关之外，Ωa 和[CO3(2-)]在珊瑚礁上没有基本的生理意义，而[DIC]：[H(+)] 比值是 G 的驱动力。
