Life history changes in coral fluorescence and the effects of light intensity on larval physiology and settlement in Seriatopora hystrix.

Fluorescence is common in both coral adult and larval stages, and is produced by fluorescent proteins that absorb higher energy light and emit lower energy light. This study investigated the changes of coral fluorescence in different life history stages and the effects of parental light environment...
