Our study highlights that differences in coral mortality from SCTLD are not necessarily linked to host species, lesion morphology is reflective of subsequent rate of mortality, and disease dynamics change through time on reefs where the disease has newly emerged.
Aquaria studies found the rate of SCTLD transmission using lesions from the different zones (emergent and endemic) were similar.
Lesion morphology on colonies was a significant predictor of amount of tissue loss. However, SCTLD dynamics changed, with year two tagged colonies showing declining disease prevalence, low mortality, and lesion morphology switched to a mixture of bleached polyps and tissue loss with or without bleached edges. In contrast, Lower Keys colonies tagged in the first year maintained 100% disease prevalence with high mortality, and disease lesions were predominantly tissue loss with no bleached edges. In both years, Fort Lauderdale colonies showed declining disease prevalence, low colony mortality, and disease lesions were mainly bleached spots lacking tissue loss. cavernosa SCTLD-affected colonies were followed for 2 years at one site in each region. siderea at Fort Lauderdale were dominated by smaller colonies (<5 cm) whereas larger colonies occurred in the Lower Keys. SCTLD prevalence was higher in the Lower Keys than at Fort Lauderdale and two of the common species, M. Reef surveys found sites in both regions had low coral cover, high algae cover, and similar coral species composition. Our objectives were to (1) assess the potential impact of SCTLD on overall reef condition by surveying reefs in each region, (2) in a single common species, Montastraea cavernosa, examine differences in SCTLD prevalence, colony mortality, and lesion morphology in each region, and (3) look for differences in contagion by conducting transmission experiments using lesions from each region. We examined two Florida sites with different temporal histories of disease emergence Fort Lauderdale where SCTLD is endemic and the Lower Florida Keys where SCTLD has recently emerged. Stony coral tissue loss disease (SCTLD) is affecting corals across the Western Atlantic and displays species-specific and regional differences in prevalence, incidence, degree of mortality, and lesion morphology. 3Mote Marine Laboratory, Elizabeth Moore International Center for Coral Reef Research and Restoration, Summerland Key, FL, United States.2Department of Biology and Marine Biology, University of North Carolina Wilmington, Wilmington, NC, United States.1Smithsonian Marine Station, Fort Pierce, FL, United States.Applications for Hyper's Fall season are open as of today, so if you’re thinking of starting a company, you should apply now.Greta Aeby 1*, Blake Ushijima 1,2, Erich Bartels 3, Cory Walter 3, Joseph Kuehl 3, Scott Jones 1 and Valerie J. We’re going to invest in a small number of startups four times per year, with the first group starting our 8-week founder program on September 10th. And what makes Hyper really interesting is how we plan to reinvest our fund profits back into the ecosystem. Hyper's investments are about a lot more than just money - we provide startups with the things they need most in today’s tech ecosystem: a great mentorship program, a helpful community, and unique distribution partnerships, among other things we’ll announce later this year.
Say hello to Hyper, a new kind of early-stage venture firm inspired by the awesome community of makers and early adopters at Product Hunt. I’m incredibly excited to finally be able to share some of that vision with you today. When Ryan Hoover introduced me as Product Hunt’s new CEO a few months ago, he teased a big vision for the future.
