Hypothesis

Does the presence of macroalgae influence the spread rates of Caribbean Yellow Band Disease in corals?

Conclusion

Macroalgae have no effect on the severity and dynamics of Caribbean Yellow Band Disease.

Supporting Evidence

  • The addition of macroalgae did not affect disease severity or coral fitness.
  • Colony survival was 100% in all treatments.
  • None of the small coral colonies treated with macroalgae became infected or died.

Takeaway

The study found that adding seaweed next to corals didn't make the coral disease worse, which is surprising because some people thought it might.

Methodology

Three field experiments were conducted to test the effects of macroalgae on coral disease spread, growth, and survival.

Limitations

The study was limited to short-term field experiments and specific coral species.

Participant Demographics

Coral colonies of Montastraea faveolata were used in the experiments.
