Hypothesis

Do coral microbiomes correlate with disease susceptibility and growth rate across coral evolution?

Conclusion

The evolution of Endozoicomonas symbiosis in corals correlates with both disease prevalence and growth rate.

Supporting Evidence

  • Microbial dominance predicts disease susceptibility in corals.
  • Endozoicomonas relative abundance explains 30% of variation in disease susceptibility.
  • Corals with high Endozoicomonas abundance show increased growth rates.

Takeaway

Corals have tiny living things called microbes that help them grow, but having too many of one type can make them sick.

Methodology

A comparative approach using a cross-species coral microbiome survey combined with long-term disease prevalence and coral trait data.

Limitations

The study relies on correlational data, which does not establish causation.
