Description

These data describe the number of brooded larvae released from colonies of two species of corals (Pocillopora damicornis, Seriatopora hystrix) freshly collected and retained in the lab at the National Museum of Marine Biology and Aquarium in Taiwan, 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 are published in Edmunds et al. (2011). J. Exp. Biol. 214, 2783-2790.

Methods & Sampling

The number of larvae released daily was recorded for Pocillopora damicornis and Seriatopora hystrix retained in aquaria for month-long periods spanning multiple lunar phases in up to 5 years between 2003 and 2008. For each sampling, colonies were collected monthly from ~6m depth in Nanwan Bay and returned to the National Museum of Marine Biology and Aquarium in Taiwan where they were placed into larval collection apparatus. Corals were replaced monthly to ensure that the laboratory measurement of larval release reflected larval release in situ, and to avoid acclimatization to laboratory conditions. Larvae were collected daily from each coral, pooled within species, and counted to evaluate larval release by day throughout each lunar month. Seawater temperature on the day of larval release was assessed from records obtained from thermisters placed at 5m depth in Nanwan Bay. The hourly values were averaged by day to describe the seawater temperature on the day of larval release.

The cumulative number of larvae released daily by P. damicornis and S. hystrix was expressed as a function of the daily seawater temperature on the day of release. Temperature was partitioned in 0.5 degree Celsius increments.

These data are published in Edmunds et al. (2011). J. Exp. Biol. 214, 2783-2790. Please see publication for additional information on methods and results.

Data 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_release.dat:

-Reorganized format of data to include all values in one columnar dataset.
-Added BCO-DMO header:
    -added parameter column and header name for species
    -edited '#Larvae' to 'count'
    -edited 'Temperature' to 'temp'
    -edited 'Temperature bin' to 'temp_bin'
    -edited 'TOTAL RELEASED' to 'count_total'
-Added 'lat' and 'lon' parameter column and header (for lab location)

-Added columns and parameter header names for 'year_begin' and 'year_end' for experimental data collection years.
-Added title and PI lines
-Added line for publication reference information to file header
