| Parameter | Description | Units |
| CO2_Treatment | The pCO2 treatments (Ambient = ~400 uatm, High = ~1000 uatm) in each flume | unitless |
| Flume | The flume numbers - 2 & 4 were maintained at ambient pCO2, 1 & 3 were maintained at ~1000 uatm | unitless |
| Arrangement | The arrangement surrounding the central P. verrucosa colonies. Coral-coral configurations were prepared to create five arrangements: (1) controls consisting of a single colony of P. verrucosa; (2) conspecific pairings, in which a colony of P. verrucosa was adjacent to a conspecific of equal size; (3) conspecific aggregations, in which a colony of P. verrucosa was surrounded by three conspecifics of equal size; (4) heterospecific pairings, in which a colony of P. verrucosa was adjacent to a fragment of Acropora hyacinthus; and (5) heterospecific aggregations, in which a colony of P. verrucosa was surrounded by three fragments of A. hyacinthus. | unitless |
| Coral | The reference number for the central P. verrucosa colony in each of the arrangements | unitless |
| Calcification | The mass of CaCO3 deposited on average each day for each central P. verrucosa colony over the course of the incubation (normalized to surface area), as measured by buoyant weight (mg CaCO3 d-1 cm-2) | mg CaCO3 d-1 cm-2 |
| Horizontal_growth | The average change in diameter per day for each central P. verrucosa colony over the course of the incubation (um d-1) | um d-1 |
| Vertical_growth | The average change in height per day for each central P. verrucosa colony over the course of the incubation (um d-1) | um d-1 |

| Description | Ongoing studies on corals |
Tropical coral reefs face a suite of environmental assaults ranging from anchor damage to the effects of global climate change (GCC). The consequences are evident throughout the tropics, where many coral reefs have lost a substantial fraction of their coral cover in a few decades. Notwithstanding the importance of reducing the impacts of environmental stresses, the only means by which these ecosystems can recover (or simply persist) is through the recruitment of scleractinians, which is a function of successful larval development, delivery, settlement, metamorphosis, and post-settlement events. Despite wide recognition of the importance of these processes, there are few pertinent empirical data, and virtually none that address the mechanisms mediating the success of early coral life stages in a physical environmental varying at multiple spatio-temporal scales.
The objective of this research is to complete one of the first comprehensive ecophysiological analyses of the early life stages of corals through a description of: (1) their functionality under 'normal' conditions, and (2) their response to the main drivers of GCC. These analyses will be completed for 2 species representative of a brooding life history strategy, and the experiments will be completed in two locations, one (Taiwan) that provides unrivalled experience in coral reproductive biology, and superb microcosm facilities, and the other (Moorea), with access to a relatively pristine environment, a well described ecological and oceanographic context (through the MCR-LTER), and the capacity to bring a strong biogeographic contrast to the project. The results of the study will be integrated through modeling to explore the effects of GCC on coral community structure over the next century.
