Dataset Description

Acropora palmata multilocus genotypes derived from five microsatellite markers.

 


Methods & Sampling

Adult Acropora palmata colonies were sampled (1 cm^2) with hammer and chisel and tissues were preserved in 96% non-denature Ethanol. DNA was extracted using the DNEasy tissue kit (Qiagen) following manufacturer’s instructions. Two multiplex Polymerase Chain Reactions (PCR) were performed per sample using fluorescently labeled primers to assay five loci containing AAT repeats. These five microsatellite loci have previously been demonstrated to be mendelian and coral-specific using controlled crosses (Baums et al., 2005). PCR products were visualized with an automated sequencer (ABI 3730). An internal size standard (Gene Scan 500-Liz, Applied Biosystems CA) ensured accurate sizing. Electropherograms were analyzed with GeneMapper Software 3.0 (Applied Biosystems, CA). Alleles were scored as PCR product size.

See Baums IB, Hughes CR, Hellberg MH (2005) for details.


Data Processing Description

Electropherograms of microsatellite alleles were scored for allele sizes (basepairs) in Genemapper vers. (Applied Biosystems) and transferred to spreadsheets. 

BCO-DMO Processing Notes:

- As per PI, edited column "Region" to the value 'Florida' (previously, this column's valuess
were all set to 'region').  It is expected that the dataset may grow with new regions in the
future.

- Added PI-provided lat/lon for each "Reef" location.

- Each locus allele size was split into separate columns (i.e., allele size 1 was the first 3 digits,
and allele size 2 were the second consecutive digits of a six digit column.  These were separated into
separate columns per allele size at each locus).

- Edited loci headers to include the word 'locus' and whether the column held values for
allele size one or two (e.g., column headers for '166' was edited to 'locus_166_allele1' and locus_166_allele2'.

- Edited entire header to BCO-DMO format (e.g., lowercase names, underscores where needed)

- Edited lat/lon values to four decimal precision consistently.

- Edited spaces in reef names to underscores

- Split date into year, month, day fromat

Dataset-specific Description
Applied Biosystems 3730 DNA Analyzer
Generic Instrument Description
General term for a laboratory instrument used for deciphering the order of bases in a strand of DNA. Sanger sequencers detect fluorescence from different dyes that are used to identify the A, C, G, and T extension reactions. Contemporary or Pyrosequencer methods are based on detecting the activity of DNA polymerase (a DNA synthesizing enzyme) with another chemoluminescent enzyme. Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it, one base pair at a time, and detecting which base was actually added at each step.

Project Information

RAPID: surviving climate change - the role of acclimatization in reef-building corals (Surviving Climate Change)

Coverage: Florida Keys National Marine Sanctuary, Key Largo area


Description from NSF award abstract:
August of 2014 was the warmest on record for the Florida Keys reef tract and by early September numerous corals species were severely stressed and looked bleached. This ongoing large-scale bleaching event provides an unprecedented opportunity to understand if prior stress exposure hardens individual coral colonies to future hot water events -- a process called acclimatization. This study combines long-term monitoring data of individual coral colonies with a stress experiment in the summer of 2015 to determine whether partially bleached colonies have acclimatized, to what extent, and by what means. The answers may fundamentally shape our understanding of how reefs might survive climate change. This is important because tropical coral reefs harbor more species then tropical rainforests and generate billions of dollars each year for local and national economies. The focal species of this project is the endangered elkhorn coral, Acropora palmata and results of the work can be used directly by managers when choosing coral colonies for conservation. The project will educate and train the public and public institutions on numerous levels. The scientists have partnered with the Coral Restoration Foundation, a non-for profit organization that delivers scientific knowledge and hands on experience in coral restoration to over 300 high school students per year. Postdoctoral scholars, and students are an integral part of this project and will receive training in field and laboratory work and lecture courses.

Acclimatization is a non-genetic process by which an individual heightens its tolerance after exposure to a stressor, such as temperature anomalies. Recent work has shown that acclimatization may be an important process by which corals may survive climate change. However, because reef-building corals harbor endosymbiotic Symbiodinium, discerning the relative contribution of host and symbiont to acclimatization can be difficult. The endangered Caribbean elkhorn coral, Acropora palmata, has an uncomplicated symbiosis: it associates with just one symbiont species (Symbiodinium fitti) and most colonies also harbor only one strain of S. fitti over space and time. August of 2014 was the warmest on record for the Florida Keys reef tract and by early September numerous corals species were severely stressed and looked bleached. This event provides an unprecedented opportunity to understand the role of acclimatization in reef corals. Initial surveys of A. palmata documented a range of bleaching response. This response varied between reefs but also within single, monoclonal stands of A. palmata. Thus, coral clone mates were observed to exhibit different bleaching susceptibilities despite indications that they share identical (clonal) symbiont communities, begging the question as to what mechanisms account for such differences. The answers may fundamentally shape our understanding of how reefs might survive climate change. Immediate support is requested to sample coral colonies while they are still bleached and for which long term performance histories exist. Results from this initial assessment are essential to inform the centerpiece of the proposal: a stress experiment to determine whether partially bleached colonies have acclimatized, to what extent, and by what means.

This is an NSF Collaborative Research project.
