在实验性光暗循环过程中，石珊瑚群落 Favia sp. 组织中的 O-2。和卫城 sp。在光照下几分钟后达到 >250% 的空气饱和度。变暗后，O-2 立即迅速耗尽，在 350 μ Ein m(-2) s(-1) 饱和辐照度下，5 min 内组织表面 O-2 浓度达到相同水动力条件下（流速 5 至 6 cm s(-1)）暗呼吸测量值的 6 倍。
During experimental Light-dark cycles, O-2 in the tissue of the colonial scleractinian corals Favia sp. and Acropora sp. reached >250% of air saturation after a few minutes in Light. Immediately after darkening, O-2 was depleted rapidly, and within 5 min the O-2 concentration at the tissue surface reached 6 times higher at a saturating irradiance of 350 mu Ein m(-2) s(-1) than the dark respiration measured under identical hydrodynamic conditions (flow rate of 5 to 6 cm s(-1)).
