Certain coral individuals exhibit enhanced resistance to thermal bleaching, yet the specific microbial assemblages and their roles in these phenotypes remain unclear. We compared communities of bleaching–resistant (TBR) bleaching–sensitive (TBS) corals using metabarcoding metagenomics. Our multidomain approach revealed stable distinct compositions between phenotypes. Notably, TBR were inherently enriched with eukaryotes, particularly Symbiodiniaceae, linked photosynthesis, biosynthesis antibiotic antitumor compounds glycosylphosphatidylinositol-anchor proteins, crucial for cell wall regulation metabolite exchange. In contrast, TBS dominated by bacterial metabolic genes related nitrogen, amino acid, lipid metabolism. The inherent microbiome differences corals, already observed before stress, point holobiont associated bleaching resistance, offering insights into mechanisms underlying response climate-induced stress.

Corals from the northern Red Sea, in particular Gulf of Aqaba (GoA), have exceptionally high bleaching thresholds approaching >5℃ above their maximum monthly mean (MMM) temperatures. These elevated are thought to be due historical selection, as corals passed through warmer Southern Sea during recolonization Arabian Sea. To test this hypothesis, we determined thermal tolerance GoA versus central (CRS) Stylophora pistillata using multi-temperature acute stress assays determine thresholds.

Climate change is turning formerly pristine ecosystems into ever-changing states, causing major disturbance and biodiversity loss. Such impacted marine organisms exhibit clear microbiome shifts that alter their function. Microbiome-targeted interventions appear as feasible tools to support organismal ecosystem resilience recovery by restoring symbiotic interactions thwarting dysbiotic processes. However, restoration rehabilitation are perceived drastic measures, since they ‘natural relationships’. What missing from this notion microbiomes already drastically differ any pre-anthropogenic state. As such, our perception definition of even ‘pristine states’ may in fact represent an disturbed/derived condition. Following this, we argue rehabilitating essential mitigate decline.

Abstract Coral reefs are under threat from disease as climate change alters environmental conditions. Rising temperatures exacerbate coral disease, but this relationship is likely complex other factors also influence prevalence. To better understand relationship, we meta‐analytically examined 108 studies for changes in global over time alongside temperature, expressed using average summer sea surface temperature (SST) and cumulative heat stress weekly anomalies (WSSTAs). We found that both rising SST WSSTA were associated with increases the mean variability Global prevalence tripled, reaching 9.92% 25 years examined, effect of ‘year’ became more stable (i.e. has lower variance time), contrasting effects two stressors. Regional patterns diverged differed response to SST. Our model predicted that, same trajectory, 76.8% corals would be diseased globally by 2100, even assuming moderate WSSTA. These results highlight need urgent action mitigate disease. Mitigating impact ocean on a challenge requiring discussion further study.
