DNA methylation regulates transcriptional homeostasis of algal endosymbiosis in the coral model Aiptasia
It is demonstrated that DNA methylation provides an epigenetic mechanism of transcriptional homeostasis that responds to symbiosis and shows enrichment for symbiosis-related processes, such as immunity, apoptosis, phagocytosis recognition, and phagosome formation, and reveal intricate interactions between the underlying pathways.
The past, present, and future of coral heat stress studies
This review summarizes the development of the field to date and assesses avenues for future research and understanding how coral heat stress studies have evolved is important for the critical assessment of their progress.

This study shows that cnidarian miRNAs recognize their mRNA targets via high‐complementarity target binding and suggests that miRNA‐mediated modulations of genes and pathways are important during the onset and maintenance of cnodarian–dinoflagellate endosymbiosis.
Integrating environmental variability to broaden the research on coral responses to future ocean conditions
A globally distributed dataset of in situ seasonal and diurnal variability of key environmental drivers critical for the growth and livelihood of reef-building corals is compiled and analyzed to highlight that a large portion of the natural environmental variability at short and long time scales is underexplored in experimental designs.

It is indicated that RS anemones do not show increased antioxidant capacity but may have adapted to higher temperatures through association with more thermally tolerant symbionts.
Unfamiliar partnerships limit cnidarian holobiont acclimation to warming
The results show that holobionts from more thermally variable environments have higher plasticity to heat stress, but this resilience could not be transferred to other host genotypes through the exchange of symbionts, and indicate that local adaptations of holobions will likely limit the efficacy of interchanging unfamiliar compartments to enhance thermal tolerance.
Projecting coral responses to intensifying marine heatwaves under ocean acidification
It is suggested that corals must rapidly adapt or acclimatize to projected ocean conditions to persist, which is far more likely under a low emissions scenario and with increasing efforts to manage reefs to enhance resilience.
Summarized datasheet for multi-omics response of three Exaiptasia strains to heat stress: a new way to process omics data
To understand mechanisms of stress tolerance in symbiotic cnidarians, the sea anemone Exaiptasia pallida from different regions was heat stressed, enabling a comparative study of local adaptation strategies.
Investing in Blue Natural Capital to Secure a Future for the Red Sea Ecosystems
For millennia, coastal and marine ecosystems have adapted and flourished in the Red Sea’s unique environment. Surrounded by deserts on all sides, the Red Sea is subjected to high dust inputs and…
For a World Without Boundaries: Connectivity Between Marine Tropical Ecosystems in Times of Change
Tropical mangrove forests, seagrass beds, and coral reefs are among the most diverse and productive ecosystems on Earth. Their evolution in dynamic, and ever-changing environments means they have…
