Stony coral tissue loss disease (SCTLD) has devastated populations along Florida’s Coral Reef and beyond. Although widespread infection mortality of adult colonies have been documented, no studies yet investigated the susceptibility recruits to this disease. Here, we subjected eight-month-old Diploria labyrinthiformis four-month-old Colpophyllia natans two sequential exposures SCTLD in laboratory track assess potential resilience. Both species began develop lesions as early 48 h after exposure began. During first exposure, 59.6% C. lost all (died) within eight days developing lesions, whereas D. experienced slower minimal eventual mortality. In , larger those fused into groups multiple genets (chimeras) exhibited highest survivorship. contrast, smaller and/or single (ungrouped) had lowest survivorship (9.9 - 24.8%). After 20 days, a second was delivered further test resistance remaining recruits, both succumbed six days. showed absolute following repeated exposures, our results provide evidence that interactions between size chimerism can impact relative . This study represents report Caribbean carries implications for natural recovery reef restoration efforts. Additional research on juveniles is urgently needed, include different species, locations, parents, algal symbionts, with goals assessing identifying sources resilience critical life history stage.

Abstract To restore degraded coral reef habitats, it is critical to ensure that the scleractinian broodstock utilized can withstand future heatwaves. However, resilience normally assessed only after catastrophic stress events. By tapping into a rich, “molecules-to-satellites” dataset acquired during Living Ocean Foundation’s research mission Republic of Palau, we trained an artificial intelligence accurately predict pocilloporid thermotolerance from relatively cheap, easy-to-measure environmental and ecological survey parameters. Specifically, neural network featuring 22 predictors, such as cover colony size, could forecast whereabouts properties climate-resilient colonies Pocillopora acuta with ~ 90% accuracy. This machine-learning model enables practitioners 1) estimate climate local populations 2) identify habitats characterized by high resilience.
