 Coral reefs are highly vulnerable to environmental stressors such as climate change, water pollution, and overfishing. These stressors often lead to changes in the coral's microbiome, which can have both positive and negative effects on the coral's health and survival. In this review, the authors found that despite these stressors, the microbial richness of corals was often higher rather than lower, suggesting that corals may be more resilient than previously thought. Additionally, certain types of bacteria were found to increase in abundance while other types decreased, indicating that the coral's microbiome may be adapting to the changing environment. Finally, the author suggests that microbes may be used to identify resilient corals and could provide insight into how corals respond to environmental stressors. This article was authored by Jamie M.
