16. Abstract (Limit: 200 words) 



This community profile provides an introduction to the ecology of the communities living 

 on and around rubble structures in the South Atlantic Bight (Cape Hatteras to Cape 

 Canaveral). The most prominent rubble structures in the bight are jetties built at the 

 entrances to major harbors. After an initial discussion of the various kinds of rubble 

 structures and physical factors that affect the organisms associated with them, the major 

 portion of the text is devoted to the ecology of rubble structure habitats. Community 

 composition, distribution, seasonality, and the recruitment patterns of the major groups 

 of organisms are described. The major physical and biological factors affecting the 

 organization of intertidal, sunlit subtidal, and shaded subtidal communities are presented 

 and the potential effects of complex interactions in structuring these communities are 

 evaluated. The profile concludes with a general review of the effects of rubble structures 

 on nearshore sediment dynamics and shoreline evolution.
