Supplementary Material: Ocean acidification but not warming alters sex determination in the Sydney rock oyster, Saccostrea glomerata
Whether sex determination of marine organisms can be altered by ocean acidification and warming during this century remains a significant, unanswered question. Here we show that exposure of the protandric hermaphrodite oyster, Saccostrea glomerata to ocean acidification, but not warming alters sex d...
