Abstract

In response to climate change, many tropical marine species are shifting their ranges into sub-tropical regions, however, there is little research focused how high latitude species will cope with these changes. The data presented in this thesis advances our current understanding of how sub-tropical corals will be impacted by ocean acidification and warming. Adult corals had reduced summer calcification rates in response to sub-bleaching level thermal stress, while juveniles showed tolerance to thermal stress, suggesting that sub-tropical juveniles may be resilient to initial temperature increases. Conversely, ocean acidification had severe impacts on juvenile calcification, causing smaller and malformed skeletons.
