Coral larvae respiration values obtained from laboratory experiments utilizing brooded coral larvae as part of a study that describes the effects of temperature on the respiration of brooded larvae of scleractinian corals, and evaluates the implications of these effects relative to seawater temperature when peak larval release occurs. These data were compared to published values extracted from literature; available in the dataset coral_larvae_comparison_respiration.
These data are published in Edmunds et al. (2011) (see p 2785 and Fig 2).

The aerobic respiration of larvae was measured between 18 and 24 March, using batches of six larvae in a glass vial. Respiration rates were measured in 2ml glass Wheaton vials filled with filtered seawater aerated and equilibrated to the treatment temperature.
Larval respiration was calculated from the O2 concentration at the start and end of 1–2h incubations, as measured using an optrode attached to a spectrophotometer. O2 concentrations were measured with the sample immersed in a water bath held at the same temperature as the incubation conditions. At the conclusion of incubations, vials were removed from the water, inverted gently to ensure mixing, and analyzed for O2 saturation using the optrode. The O2 saturation in the seawater within the vial was then measured at the incubation temperature and converted to O2 concentration, with the change in concentration serving as the measure of aerobic dark respiration after adjusting for O2 fluxes in control vials. Larval respiration was expressed as nmol O2 larva–1 min–1.

| Description | Experiments related to the research project: 'RUI- The ecophysiological basis of the response of coral larvae and early life history stages to global climate change' were conducted at the laboratories of the National Museum of Marine Biology and Aquarium in Southern Taiwan. |
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.
