The rapid loss of reef-building corals owing to ocean warming is driving the development interventions such as coral propagation and restoration, selective breeding assisted gene flow. Many these target naturally heat-tolerant individuals boost climate resilience, but challenges quickly reliably quantifying heat tolerance identifying thermotolerant have hampered implementation. Here, we used bleaching automated stress systems perform rapid, standardized assays on 229 colonies Acropora...

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...

Abstract The carbon isotope fractionation in algal organic matter (ε p ), including the long‐chain alkenones produced by coccolithophorid family Noelaerhabdaceae, is used to reconstruct past atmospheric CO 2 levels. conventional proxy linearly relates ε changes cellular demand relative diffusive supply, with larger values occurring at lower supply (i.e., abundant ). However, response of Gephyrocapsa oceanica , one dominant alkenone producers last few million years, has not been studied...

Abstract Long-read sequencing is revolutionizing de-novo genome assemblies, with continued advancements making it more readily available for previously understudied, non-model organisms. Stony corals are one such example, long-read assemblies now starting to be publicly available, opening the door a wide array of ‘omics-based research. Here we present new assembly endangered Caribbean star coral, Orbicella faveolata , using PacBio circular consensus reads. Our improved contiguity (51 versus...

The effects of turbidity and sedimentation stress on early life stages corals are poorly understood, particularly in Atlantic species. Dredging operations, beach nourishment, other coastal construction activities can increase nearby coral reef habitats have the potential to negatively affect larval development metamorphosis, reducing sexual reproduction success. In this study, we investigated performance larvae threatened Caribbean species Orbicella faveolata exposed suspended sediments...

Cryopreservation of coral sperm requires reliable, travel-ready, inexpensive hardware. To this end, we developed and tested a robust, second-generation, conduction-based cryovial cooling rack assembled from 3D-printed commercially available parts. Cooling rates -10 to -80 °C were found be repeatable at -22.9 ± 1.9 (rate SD) °C/min for 1-mL samples -35.4 3.3 0.5-mL samples. This represents an improvement on the variability in older design, which was -31.8 7.1 Design files manual produced...

Here, we provide the first reports of spawning activity by Acropora palmata colonies outplanted to reefs in Florida, USA. In 2020, observed light from A. five years after they had been on two Florida reefs. 2021 and 2022, synchronously with other nearby (<3 m) outplants wild more than 100 m away. During 2022 event, some spawned as few four outplanted. Among all seasons, gametes collected yielded high fertilization rates viable larvae. These observations are promising for restoration...

Abstract Many reef invertebrates reproduce through simultaneous broadcast spawning, with an apparent advantage of overwhelming potential predators and maximizing propagule survival. Although fish have been observed to consume coral gamete bundles during spawning events, there are few records such predation by benthic invertebrates. Here, we document several instances the ruby brittle star, Ophioderma rubicundum , capturing consuming egg‐sperm mountainous star coral, Orbicella faveolata...

Abstract Intervention strategies to enhance coral resilience include manipulating the association between corals and their algal endosymbionts. While hosting thermotolerant Durusdinium trenchii can increase bleaching thresholds in adults, its effects remain largely unknown during early life stages of Caribbean corals. Here, we tested if Orbicella faveolata recruits could establish symbiosis with D. supplied by nearby “donor” colonies examined resulting ecological trade-offs evaluate...
