The proteomic response of larvae of the Sydney rock oyster, saccostrea glomerata to elevated pCO 2
The acidification of oceans is predicted to fundamentally alter marine ecosystems. Previous studies have found that elevated CO 2 has an effect on adult calcification, fertilisation and larval development, perhaps because of the organisms' inability to regulate acid-base status, but little is k...
