Chimerism as a strategy to improve the resilience of boulder corals [PDF]

Scientific Reports
Chimeras form by the fusion of at least two distinct genets. Such genetic heterogeneity has been hypothesized to increase resilience of clonal invertebrates, and, given the changing environment of coral reefs, may provide important benefits in coral ...

RNA-Seq of the Caribbean reef-building coral Orbicella faveolata (Scleractinia-Merulinidae) under bleaching and disease stress expands models of coral innate immunity [PDF]

PeerJ, 2016
Climate change-driven coral disease outbreaks have led to widespread declines in coral populations. Early work on coral genomics established that corals have a complex innate immune system, and whole-transcriptome gene expression studies have revealed ...

Gene expression of settled and metamorphosed Orbicella faveolata during establishment of symbiosis [PDF]

, 2017
Corals rely on a symbiosis with dinoflagellate algae (Symbiodinium spp.) to thrive in nutrient poor tropical oceans. However, the coral-algal symbiosis can break down during bleaching events, potentially leading to coral death. While genome-wide expression studies have shown the genes associated with the breakdown of this partnership, the full ...

Recent decade of growth and calcification of Orbicella faveolata in the Florida Keys: an inshore-offshore comparison [PDF]

Marine Ecology - Progress Series, 2015
Coral reefs along the Florida Keys portion of the Florida Reef Tract (FRT) have undergone a dramatic decline since the 1980s. Since the 1997−1998 El Nino event, coral cover on offshore reefs of the FRT has been ≤5% and continues to decline. Mortality of the frameworkconstructing coral in the Orbicella (formerly Montastraea) annularis species complex ...

Speciation across depth gradients in reef corals [PDF]

Nature Communications
Ecological speciation through adaptation to different habitats can readily occur without strong geographic isolation when the same traits underlie both ecological divergence and reproductive isolation.

Differentiation of the bacterial communities associated with Orbicella faveolata across different growth conditions and life-cycle stages. [PDF]

PLoS One
The coral microbiome can strongly influence coral health, development, and resilience. While larval settlement is fundamental for coral restoration efforts using assisted larval propagation, post-settlement survival remains a major challenge. The study of lab-bred Orbicella faveolata settlers

Prevalence and progression of macroscopic lesions in Orbicella annularis and O. faveolata on shallow fringing reefs of St. Kitts [PDF]

Diseases of Aquatic Organisms, 2020
The endangered coralsOrbicella annularisandO. faveolataare crucial to Caribbean reefs because of their large size and contribution to reef framework. The objective of this study was to describe the prevalence and progression of macroscopically evident lesions affectingOrbicellaspp. in shallow fringing reefs in St. Kitts.

Algal symbiont genera but not coral host genotypes correlate to stony coral tissue loss disease susceptibility among Orbicella faveolata colonies in South Florida

Frontiers in Marine Science
Stony coral tissue loss disease (SCTLD) has spread throughout the entirety of Florida’s Coral Reef (FCR) and across the Caribbean, impacting at least 30 coral species.

Genotype and symbiont composition rather than environment influence susceptibility to stony coral tissue loss disease in coral restoration broodstock [PDF]

Scientific Reports
Over the last several decades, Florida’s Coral Reef has been impacted by global and local stressors causing significant declines in living coral with no signs of natural recovery.

Metatranscriptome analysis of the reef-buidling coral Orbicella faveolata indicates holobiont response to coral disease [PDF]

Frontiers in Marine Science, 2015
White Plague Disease (WPD) is implicated in coral reef decline in the Caribbean and is characterized by microbial community shifts in coral mucus and tissue.
