[Coral-List] Amazing coral cover!

Impressive cover indeed. Lisa Greer is working on a reef in Belize that is
similarly robust but likewise not particularly diverse in its shallower
portions. The deeper sites look like a number I've seen (lots of *Madracis*
coming in) and are still good news.

It is interesting that the shallower reef seems to be *mostly** A.
cervicornis* and *Agaricia tenufolia* (or whatever we are agreeing to call
it these days). If I remember the story correctly, the excellent Aronson
and Precht papers from years back described them as different reef states.
That aside, neither species is a major reef builder except in the western
Caribbean or protected bays where wave energy is low enough to allow them
to accumulate. But.... they'll make a lot of good sediment if it's not all
exported by increasing storminess. It would be very interesting to look at
the stratigraphy of this reef to see whether it has been like this for a
long time or if this is something new. It has been my experience that these
are often opportunist species (I'd say "weedy" except for the connotation
that "weeds are bad").

Thanks for the video. It will be a nice break from the "gloom and doom"
that increasingly dominates my *Coral Reefs* course.
