[Coral-List] new sponge climate record

   Interesting observation, and I agree. We have spent far too much time
   waffling about "framework." It's a good way to distinguish coral reefs
   from piles of oyster shells, but tends to fall apart when looked at
   closely.

   I have an old paper on a (tiny) stromatoporoid reef on Manitoulin
   Island. The critters themselves were about the size of a large
   grapefruit, and about the same shape. We were looking at evidence of
   transport, so started counted the ones that were upside-down vs
   rightside-up.

   50:50

   Which led us to the conclusion that the ones in "life position" were
   simply ones that had been rolled an even # of times, as opp to those
   rolled an odd #. Framework?

   Phil:
   Thanks for your historical commentl. One ooooold question on your use
   of "framework. How specifically are you using this definition? In the
   60s and 70s, we spent way too much time trying to convince ourselves
   that a "reef": was a feature largely constructed from in-place corals..
   As one who looked at "reefs" in core as much as biological entities we
   swam over, it was pretty obvious that these were more "garbage piles"
   held together by secondary biological and chemical "cements" than
   purely biologically built, in-place  features. Some have called
   seawalls and breakwater "reefs" but I think those of us on the
   listserve all agree that these are not what we are talking about on the
   listserve.
   Best,
   Denny

     Hi Mike,
      Tom Goreau discovered the "beasts" living in the depths of
     Discovery Bay
     in the 1960. He and Willard Hartman figured out what they were. Then
     Tom
     found them living in shallow caves at Pear Tree Bottom. Lynton Land
     brought
     Nekton to DBMT in 1972 and we found them to be major framework
     builders to
     around 300 ft.
     In the 1970's I dove a site in Reading to the west of Montego Bay
     where we
     found them living in great profusion at 50-80 ft.  They are very
     slow
     growing  at 1 to 2 mm/yr; consequently their skeletons are in
     equilibrium
     with seawater. I have a pre-CITES collection if anyone is interested
     in a
     collaboration.
