Hypothesis
Are there demersal free-living Symbiodinium populations in Caribbean reefs and can Sparisoma viride disperse them?
Conclusion
The study found that free-living Symbiodinium populations exist in Caribbean reefs and are likely dispersed by the stoplight parrotfish.
Supporting Evidence
- Free-living Symbiodinium were found in macroalgal beds.
- Sparisoma viride feces contained viable Symbiodinium cells.
- Molecular analysis confirmed the identity of Symbiodinium types.
Takeaway
This study shows that tiny organisms called Symbiodinium can live freely in the ocean and are spread around by a fish called the stoplight parrotfish.
Methodology
Samples were collected from various reefs using SCUBA diving, and DNA analysis was performed to identify Symbiodinium.
Limitations
The study may not cover all habitats where Symbiodinium could exist, and the identification of clade C is not precise.
