Dear Mr. Shinn and interested Coral-List readers:

I believe that Professor Terry Hughes from James Cook University,  
Townsville Australia (and associates) has conducted some large scale  
studies in this, and other relative areas.  If interested, please  
refer to the publications cited below, I hope they may be of some

study of competition and diversity of corals. Ecological Monographs
