Abstract/Description
Stony coral tissue loss disease (SCTLD) emerged in 2014 and has since spread across Florida’s Coral Reef (FCR) and the Caribbean. This thesis is part of a larger project assessing the efficacy of restoring SCTLD-susceptible corals Montastraea cavernosa, Orbicella faveolata, and Pseudodiploria clivosa in SCTLD endemic areas. As part of Florida’s largest coral restoration experiment to date, 1,152 cement bases with 5,760 coral fragments from 99 source colonies were outplanted across six regions...
Show moreStony coral tissue loss disease (SCTLD) emerged in 2014 and has since spread across Florida’s Coral Reef (FCR) and the Caribbean. This thesis is part of a larger project assessing the efficacy of restoring SCTLD-susceptible corals Montastraea cavernosa, Orbicella faveolata, and Pseudodiploria clivosa in SCTLD endemic areas. As part of Florida’s largest coral restoration experiment to date, 1,152 cement bases with 5,760 coral fragments from 99 source colonies were outplanted across six regions throughout FCR and monitored monthly over two years for survival, disease, and growth. Before outplanting, coral tissue samples were collected for high-resolution 2bRAD and ITS2 sequencing to genotype the corals and characterize their initial algal symbiont communities. Neither host genetic lineages nor algal symbiont types significantly affected SCTLD susceptibility or survival, negating the hypothesis of SCTLD-resistant “super coral” lineages. Results from this study will inform the feasibility and design of future coral restoration efforts in SCTLD endemic zones to maintain or enhance coral biodiversity.

Abstract/Description
Since the emergence of stony coral tissue loss disease (SCTLD) in 2014, 60% of live coral cover on Florida’s coral reefs have been lost. This study assessed the efficacy of outplanting microfragment colony arrays of three SCTLD-susceptible coral species (Montastraea cavernosa, Orbicella faveolata, and Pseudodiploria clivosa) as remediation technique in two SCTLD-degraded reef areas, St. Lucie Reef and Palm Beach, in southeast Florida. After approximately 2 years, outplanted colonies at both...

This study assessed the efficacy of outplanting microfragment colony arrays of three SCTLD-susceptible coral species (Montastraea cavernosa, Orbicella faveolata, and Pseudodiploria clivosa) as remediation technique in two SCTLD-degraded reef areas, St. Lucie Reef and Palm Beach, in southeast Florida. After approximately 2 years, outplanted colonies at both reefs experienced ≥ 75 % survivorship, net positive growth rates, and fragment fusion, with some variation between species and across reefs. Additionally, outplanting SCTLD-susceptible species did not increase local disease prevalence and resulted in low disease prevalence on the outplanted colonies. The results from this study will be used to inform and optimize ongoing and future outplanting based coral restoration projects throughout Florida’s coral reefs and the wider Caribbean.
