Ocean acidification has no effect on thermal bleaching in the coral Seriatopora caliendrum
The objective of this study was to test whether elevated pCO2 predicted for the year 2100 (85.1 Pa) affects bleaching in the coral Seriatopora caliendrum (Ehrenberg 1834) either independently or interactively with high temperature (30.5 C). Response variables detected the sequence of events associat...
