Dataset: Symbiont community structure in Orbicella faveolata from Mermaid Reef and Sandy Cay Reef in Abaco, The Bahamas in January 2019

Tissue samples from colonies of O. faveolata were collected from Mermaid Reef and sensitive Sandy Cay Reef between 21 and 24 January 2019. Genomic DNA from each coral sample was extracted and assayed using qPCR targeting loci specific to O. faveolata and each of four symbiont genera (Symbiodinium, Breviolum, Cladocopium, and Durusdinium). All reactions were performed on a QuantStudio 3 Real-Time PCR system (Life Technologies, Foster City, CA, USA). The resulting cycle threshold (CT) values at a set threshold of delta Rn = 0.01 were used for data analysis.
