Hypothesis
Are coral reefs more resilient to repeat heatwave events than previously thought?
Conclusion
Coral reefs in the Seychelles are recovering faster from the 2016 heatwave compared to the 1998 event, indicating increased resilience.
Supporting Evidence
- Coral recovery was faster after the 2016 heatwave compared to the 1998 event.
- One reef transitioned from macroalgal dominance back to coral dominance after the 2016 heat stress.
- Benthic and fish communities showed greater resistance to change following the 2016 heatwave.
Takeaway
Coral reefs can bounce back quicker after getting hot and stressed multiple times, which is good news for their future.
Methodology
The study used a 28-year dataset to assess coral recovery and community composition on 17 reefs in the Seychelles after two major heatwave events.
Limitations
The study is limited by the availability of long-term ecological datasets and the potential biases in heat stress estimates.
