Dear Bruce et al.
I may have a "marker" for past die-offs and "rebirths" within your corals.  In a matter of days following the death of a coral its skeletons will be invaded by a suite of microborers (chlorophytes, cyanobacteria) very different from the Ostreobium sp. that inhabit coral skeletons beneath living tissue.  Ostreobium is a low light specialist and is likely to be the only one to survive after the tissue regrowth.  I have proposed this microboring marker for a potential indicator of previous bleaching events.  Your tissue die-off/rebirth events may be an easier marker to detect (?).
