Description

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).

Methods & Sampling

Dataset acquisition description

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. O₂concentrations 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.

Dataset Processing Description

BCO-DMO Processing Notes:

- Original file: “Date in Edmunds et al. JEB 2011 copy.xls” contained several sheets. This file was split into four separate datasets

- Resultant datasets were edited in excel by adding BCODMO convention header line, PI and comment lines. The following edits were made to the file coral_larvae_respir:

-Added BCO-DMO header
    -replaced space in genus species name with underscore
-edited '# of Larvae' to 'number'
    -edited 'nmol/Larvae/min' to 'O2_respir_nmol'
-Added column for 'lat' and 'lon', using location for the National Museum of Marine
    Biology and Aquarium of Taiwan (experiment site)
-Added title, version, and PI lines
-Added line for publication reference information to file header
