Scleractinian corals' microbial symbionts influence host health, yet how coral microbiomes assembled over evolution is not well understood. We survey bacterial and archaeal communities in phylogenetically diverse Australian corals representing more than 425 million years of diversification. show that are anatomically compartmentalized both modern ecology evolutionary assembly. Coral mucus, tissue, skeleton differ community composition, richness, response to vs. environmental drivers. also...
In recent decades, coral reef ecosystems have declined to the extent that reefs are now threatened globally. While many water quality parameters been proposed contribute declines, little evidence exists conclusively linking specific with increased disease prevalence in situ. Here we report from situ health surveys confirming chronic exposure dredging-associated sediment plumes significantly increase of white syndromes, a devastating group globally important diseases. Coral were conducted...
Our paper is the first study to synthesize currently available but decentralized data of cultured microbes associated with corals. We were able collate 3,055 isolates across a number published studies and unpublished collections from various laboratories researchers around world.
Coral reef restoration is a rapidly growing movement galvanized by the accelerating degradation of world's tropical coral reefs. The need for concerted and collaborative action focused on recovery ecosystems coalesced in creation Restoration Consortium (CRC) 2017. In March 2020, CRC leadership team met biennial review international efforts discussion perceived knowledge implementation bottlenecks that may impair scalability efficacy. Herein we present six priorities wherein will foster...
Abstract V ibrio coralliilyticus is an important coral pathogen demonstrated to cause disease outbreaks worldwide. This study investigated the feasibility of applying bacteriophage therapy treat . A specific for strain P1 ( LMG23696 ), referred here as YC , was isolated from seawater above corals at N elly B ay, M agnetic I sland, central G reat arrier R eef GBR same location where bacterium first isolated. Bacteriophage shown be a lytic phage belonging yoviridae family, with rapid...
Here we describe an efficient and effective technique for rearing sexually-derived coral propagules from spawning through larval settlement symbiont uptake with minimal impact on natural populations. We sought to maximize survival while minimizing expense daily husbandry maintenance by experimentally determining optimized conditions protocols gamete fertilization, cultivation, induction of crustose coralline algae, inoculation newly settled juveniles their dinoflagellate Symbiodinium. Larval...
Disease is an emerging threat to coral reef ecosystems worldwide, highlighting the need understand how environmental conditions interact with immune function and associated microbial communities affect holobiont health. Increased disease incidence on reefs adjacent permanently moored platforms Australia's Great Barrier Reef provided a unique case study investigate environment-host-microbe interactions in situ. Here, we evaluate coral-associated bacterial community (16S rRNA amplicon...
ABSTRACT Coral tissue loss diseases, collectively known as white syndromes (WSs), induce significant mortality on reefs throughout the Indo-Pacific, yet definitive confirmation of WS etiologies remains elusive. In this study, we integrated ecological disease monitoring, bacterial community profiling, in situ visualization microbe-host interactions, and cellular responses host coral through an 18-month repeated-sampling regime. We assert that observed pathogenesis lesions acroporid corals at...
Abstract Background Evolutionary tradeoffs between life-history strategies are important in animal evolution. Because microbes can influence multiple aspects of host physiology, including growth rate and susceptibility to disease or stress, changes animal-microbial symbioses have the potential mediate tradeoffs. Scleractinian corals provide a biodiverse, data-rich, ecologically-relevant system explore this idea. Results Using comparative approach, we tested if coral microbiomes correlate...
ABSTRACT Rhodolith beds are biogenic marine habitats formed by aggregations of free‐living crustose coralline algae. New descriptions rhodolith fill the gaps in our understanding global distribution and ecological significance these understudied habitats. We provide first characterisation a network associated with coral reefs tropical central Pacific. surveyed shallow eastern reef flat Palmyra Atoll to evaluate spatial extent biodiversity habitat relative adjacent reefs. mapped 15 discrete...
In situ visualization of microbial communities within their natural habitats provides a powerful approach to explore complex interactions between microorganisms and macroscopic hosts. Specifically, the application fluorescence in hybridization (FISH) simultaneously identify visualize diverse taxa associated with coral hosts, including symbiotic algae ( Symbiodinium ), Bacteria, Archaea, Fungi protists, could help untangle structure function these holobiont. However, FISH approaches samples...
Abstract Bacterial diversity associated with corals has been studied extensively, however, localization of bacterial associations within the holobiont is still poorly resolved. Here we provide novel insight into coral-associated microbial aggregates (CAMAs) tissues coral Acropora hyacinthus. In total, 318 and 308 CAMAs were characterized via histological fluorescent in situ hybridization (FISH) approaches respectively, shown to be distributed extensively throughout collected from five sites...
Abstract Degradation of water optical properties due to anthropogenic disturbances is a common phenomenon in coastal waters globally. Although this condition associated with multiple drivers that affect corals health ways, its effect on light availability and photosynthetic energy acquisition has been largely neglected. Here, we describe how declining the quality reef exposed turbid plume originating from man-made channel compromises functionality keystone coral species Orbicella faveolata ....
A phenotypic and phylogenetic comparison of geographically disparate isolates the coral pathogen Vibrio coralliilyticus was conducted to determine whether bacterium exists as a single cosmopolitan clonal population, which might indicate rapid spread pandemic strain, or is grouped into endemic genotypically distinct strains. All strains included in this study displayed similar characteristics those typed V. strain LMG 20984(T) . Five marker genes (16S, rpoA, recA, pyrH dnaJ) frequently used...
Abstract Coral reefs are undergoing degradation due to overexploitation, pollution, and climate change. Management restoration efforts require that we gain a better understanding of the complex interactions between corals, their microbiomes, environment. For this purpose, Varadero Reef near Cartagena, Colombia, serves as an informative study system located at entrance Bay Cartagena adjacent Canal del Dique, which carries turbid polluted water into bay. Varadero’s survival under poor...
Temperate oyster and tropical coral reefs are analogous systems that create habitat for economically, ecologically, culturally important species, they provide countless ecosystem services to human coastal communities. Globally, imperiled by multiple anthropogenic stressors, particularly climate impacts. Using aquaculture support conservation goals - known as is a relatively new approach many reef building but it shows great promise promoting species recovery bolstering resilience stressors....
