“…Within the overall changes, we identified 12 microorganisms from multiple species of apparently healthy corals that shifted across reef zones regardless of species. Many of these microbes frequently associate with corals, including Paramoritella ( 66 ), Acinetobacter ( 67 , 68 ), Alteromonas ( 69 ), Balneola ( 70 ), and Rubritalea ( 71 ). Given the strong influence of zones on host microbiomes, further studies on microbiomes associated with coral diseases should consider and control for regional changes in microbial communities.…”

As coral reef ecosystems experience unprecedented change, effective monitoring of reef features supports management, conservation, and intervention efforts. ‘Omics techniques show promise in quantifying key components of reef ecosystems, dissolved metabolites and microorganisms, that may serve as invisible sensors for reef ecosystem dynamics. Dissolved metabolites are released by reef organisms and transferred among microorganisms, acting as chemical currencies, and contributing to nutrient cycling and signaling on reefs. Here we applied four ‘omics techniques (taxonomic microbiome via amplicon sequencing, functional microbiome via shotgun metagenomics, targeted metabolomics and untargeted metabolomics) to waters overlying Florida’s Coral Reef, as well as microbiome profiling on individual coral colonies from these reefs to understand how microbes and dissolved metabolites reflect biogeographical, benthic and nutrient properties of this 500-km barrier reef. We show that the microbial and metabolite ‘omics approaches both differentiated reef habitats based on geographic zone. Further, seawater microbiome profiling and targeted metabolomics were significantly related to more reef habitat characteristics, such as amount of hard and soft coral, compared to metagenomic sequencing and untargeted metabolomics. Across five coral species, microbiomes were also significantly related to reef zone, followed by species and disease status, suggesting that the geographic water circulation patterns in Florida also impact the microbiomes of reef builders. A combination of differential abundance and indicator species analyses revealed metabolite and microbial signatures of specific reef zones, which demonstrates the utility of these techniques to provide new insights into reef microbial and metabolite features that reflect broader ecosystem processes.

“…Photosymbionts can produce DMSP and various breakdown products (e.g., DMS, acrylate, and methanesulfonic acid) performing a protective function against heat or oxidative stress on the host surface [ 44 ]. Therefore, these bioactive compounds may prevent bleaching and pathogenic invasion of corals [ 45 ]. The present study suggests that three beneficial bacteria, Acinetobacter , Endozoicomonas , and Ruegeria , are associated with NGCA, possibly supporting host metabolism.…”

“…Besides this, Acinetobacter may also interact with metabolic compounds produced by coral hosts (Ding et al, 2016; Horinouchi et al, 1997). Inprevious studies, Acinetobacter has been found to have a broader geographic range and less host specificity than the coral symbiotic bacteria Endozoicomonas (Yang et al, 2020, 2017). In this study, Acinetobacter is represented as one of the core coral bacterial genera in both S. pistillata and P. acuta in all temperature fluctuation treatments, indicating that it could be more flexible than other bacteria with different coral species and temperature conditions.…”

Coral reef ecosystems support over a quarter of the world’s marine life and play important ecological and economic roles. However, the increasingly severe weather events associated with ocean warming and climate change are believed to be rapidly altering the functions of coral reefs and their ecosystems. Corals and their associated microbiota form a “holobiont,” which includes symbiotic algae and other associated microbiota dominated by bacteria. These microbiota have a direct relationship with the health of the coral host. Their composition is influenced by various environmental factors, such as increasing sea water temperatures. Previous studies of the effects of temperature changes on coral physiology and associated bacterial communities have been conducted based on stable water temperatures set by mean temperatures, or by slowly increasing/decreasing temperatures. However, the daily temperature fluctuations that corals experience in nature are not stable. Rather, there may be significant differences of up to 6°C in a single day. The current understanding of the effects of large daily temperature fluctuations on coral and associated bacterial community dynamics is limited. Hence, in this study, we conducted a four-week tank experiment using different large daily temperature fluctuations accompanied by continuous warming conditions to investigate the effects on two common reef-building corals,Stylophora pistillataandPocillopora acuta, in Taiwan. During the experiment, the activity of coral host catalase was measured, the photosynthetic ability of symbiotic algae was recorded, and the variation in bacterial communities was analyzed using the V6-V8 region of 16S rDNA. According to the results, different parts of the holobionts of different coral species exhibited varying response rates to the continuous warming conditions and diurnal temperature fluctuations. Additionally, it was found that diurnal temperature fluctuations may mitigate the heat stress on the host and reduce the changes in bacterial response to warming. Furthermore, the holobionts of different coral species may adopt different adaptation and survival strategies in response to diurnal temperature fluctuations and warming. Finally, based on the response of these two coral species under the conditions of diurnal temperature fluctuations and continuous warming,AcinetobacterandRhodobacteraceaewere identified as potential indicator coral-associated bacteria. This is the first study to investigate the tripartite dynamic response of coral, symbiotic algae and bacteria to daily temperature fluctuations.
