Hypothesis
What are the long-term effects of the cleaner fish Labroides dimidiatus on coral reef fish communities?
Conclusion
The removal of cleaner fish led to smaller sizes and lower abundances and species richness of coral reef fish communities.
Supporting Evidence
- Fish on reefs without cleaner fish were 37% less abundant.
- Species richness of resident fish was 23% lower on removal reefs.
- Juvenile visitor fish were 65% less abundant on reefs without cleaners.
Takeaway
Cleaner fish help other fish grow bigger and live better, so when they are removed, the other fish get smaller and fewer.
Methodology
The study involved removing cleaner fish from patch reefs and comparing fish size, abundance, and species richness over 8.5 years.
Potential Biases
Potential biases may arise from the specific locations and conditions of the reefs studied.
Limitations
The study was limited to specific reef areas and may not generalize to all coral reef ecosystems.
Participant Demographics
The study focused on coral reef fish communities, particularly damselfishes.
