Dense assemblages of infauna! organisms are of three types: burrowing deposit feeders, suspension feeders, and tube builders. Such assemblages are discrete, often age-class dominated, and have sharp boundaries with neighboring assemblages. The hypothesis presented is that the sharp boundaries observed among assemblage types and the maintenance of these discrete dense assemblages in infauna! systems is due to interactions among the established infaunal individuals and settling larvae....
