>Dear Hector:
>The problem with that hypothesis is that it won't explain coral mortality
in the middles of colonies as opposed to edges.  In mid-colonies, tissues
start to thin because of decreased food supply etc., and then the
semi-exposed skeletons become colonized by algae etc.  Given the simple
tissue structure of corals, there may be some "live tissue" still left on
the skeleton at the time the colonization begins, but not enough to really
constitute a defense of the skeleton.  Not sure if you see my point, but
something to think about.
