Abstract
Larval respiration was measured in a confined respirometer use a Ruthenium-based optrode (FOXY-R, 1.58 diameter, Ocean Optics) connected to a spectrophotometer (USB2000, Ocean Optics) and interfaced with a computer running the manufacturers software (OOISensor, version 1.00.08). The optrode was calibrated using a zero solution (0.01 M Na2B4O7·10H2O supersaturated with Na2SO3) and 100% air saturation usingwater-saturated air at the treatment temperature. Tomeasure respiration, 6 larvae were removed from the tubs in the treatment tanks and placed into 2-mL glass Wheaton vials filled with filtered seawater from the same treatment tank and sealed with Parafilm. A study conducted concurrently with the present analysis demonstrated that respiration of P. damicornis larvae in identical vials could be measured accurately with 5 larvae vial-1 (Edmunds et al., 2011).
Initial O2 concentration in the seawater was determined before the vials were sealed, and vials without larvae used as controls. Larvae in the sealed vials were incubated at their temperature treatments for 1.5-2 h in the dark using water baths set to the temperature of the respective treatments (±0.1 °C, Hipoint, models LC-06 and LC-10); vials were carefully moved throughout the incubations to ensure the seawater remained mixed. Incubation timeswere selected to ensure O2 concentrations remained >75% saturation. On completion of the incubations, vials were removed from the water baths, gently inverted to mix the seawater, and analyzed for O2 saturation. O2 saturation was converted to concentration using tabulated values of O2 solubility (N. Ramsing and J. Gundersen at http://www.unisense.com [based on Garcia and Gordon, 1992]) and the temperature and salinity of the seawater, and the change in O2 concentration used to calculate O2 flux after adjusting for controls. The respiration rates are expressed as nmol O2 mg protein-1 min-1.
The 'ambient' and 'high' pCO2 levels: 49.4 Pa versus 86.2 Pa
The 'ambient' and 'high' temperatures: 24.00 °C [ambient] versus 30.49 °C

| Generic Instrument Description | The LI-192 Underwater Quantum Sensor (UWQ) measures underwater or atmospheric Photon Flux Density (PPFD) (Photosynthetically Available Radiation from 360 degrees) using a Silicon Photodiode and glass filters encased in a waterproof housing. The LI-192 is cosine corrected and features corrosion resistant, rugged construction for use in freshwater or saltwater and pressures up to 800 psi (5500 kPa, 560 meters depth). Typical output is in um s-1 m-2. The LI-192 uses computer-tailored filter glass to achieve the desired quantum response. Calibration is traceable to NIST. The LI-192 serial numbers begin with UWQ-XXXXX. LI-COR has been producing Underwater Quantum Sensors since 1973.
These LI-192 sensors are typically listed as LI-192SA to designate the 2-pin connector on the base of the housing and require an Underwater Cable (LI-COR part number 2222UWB) to connect to the pins on the Sensor and connect to a data recording device.
The LI-192 differs from the LI-193 primarily in sensitivity and angular response.
193: Sensitivity: Typically 7 uA per 1000 umol s-1 m-2 in water. Azimuth: < ± 3% error over 360° at 90° from normal axis. Angular Response: < ± 4% error up to ± 90° from normal axis.
192: Sensitivity: Typically 4 uA per 1000 umol s-1 m-2 in water. Azimuth: < ± 1% error over 360° at 45° elevation. Cosine Correction: Optimized for underwater and atmospheric use.

Moorea Coral Reef Long-Term Ecological Research site (MCR LTER)
From http://www.lternet.edu/sites/mcr/ and http://mcr.lternet.edu/:
The Moorea Coral Reef LTER site encompasses the coral reef complex that surrounds the island of Moorea, French Polynesia (17°30'S, 149°50'W). Moorea is a small, triangular volcanic island 20 km west of Tahiti in the Society Islands of French Polynesia. An offshore barrier reef forms a system of shallow (mean depth ~ 5-7 m), narrow (~0.8-1.5 km wide) lagoons around the 60 km perimeter of Moorea. All major coral reef types (e.g., fringing reef, lagoon patch reefs, back reef, barrier reef and fore reef) are present and accessible by small boat.
The MCR LTER was established in 2004 by the US National Science Foundation (NSF) and is a partnership between the University of California Santa Barbara and California State University, Northridge. MCR researchers include marine scientists from the UC Santa Barbara, CSU Northridge, UC Davis, UC Santa Cruz, UC San Diego, CSU San Marcos, Duke University and the University of Hawaii. Field operations are conducted from the UC Berkeley Richard B. Gump South Pacific Research Station on the island of Moorea, French Polynesia.
MCR LTER Data: The Moorea Coral Reef (MCR) LTER data are managed by and available directly from the MCR project data site URL shown above. The datasets listed below were collected at or near the MCR LTER sampling locations, and funded by NSF OCE as ancillary projects related to the MCR LTER core research themes.

The ecophysiological basis of the response of coral larvae and early life history stages to global climate change (Climate_Coral_Larvae)
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.
