Hypothesis
Do corals elevate extracellular pH under their calcifying tissue to promote skeleton formation?
Conclusion
The study found that corals elevate the pH under their calcifying tissue, which may aid in skeleton formation.
Supporting Evidence
- Corals were found to elevate extracellular pH by approximately 0.5 and 0.2 pH units in light and dark conditions, respectively.
- The intracellular pH of the calicoblastic epithelium remained stable regardless of light conditions.
- The study provides a novel method for investigating coral physiology and calcification processes.
Takeaway
Corals can make the water under their skin more basic, which helps them build their skeletons better.
Methodology
The study used live tissue imaging and pH measurements in corals to assess pH levels under the calicoblastic epithelium.
Limitations
Observations were made at the margin of corals grown on glass coverslips, which may not fully represent conditions in naturally formed corals.
