Does a darker surface mean the same change underneath?
Florida Keys, 2024: shaded corals of two species were darker during peak heat.
Two measurements
Algal symbionts are tiny partners that help feed coral. The team measured their cell numbers relative to coral cells, alongside visible color. During warming, however, neither species showed a statistically significant shaded/control difference in symbiont-to-host cell-ratio change rates. That does not establish equivalence. Researchers proposed edge sampling and chlorophyll changes as explanations, without establishing either.
A short limit
Neither group showed bleaching-related mortality, so a survival benefit remains unproven.
