The model associates population distribution with seasonal changes in key physical variables, productivity features, and the predator-prey relationships of the estuary. trophic levels of the estuary. Of the 10 numerically dominant infaunal species (representing over 83 of the total number), five are detrital feeders, four are deposit feeders (surface and subsur- face), and one is a filter feeder. Of the entire infaunal assemblage, there are fifteen omnivore/carnivore types, seven subsurface deposit feeders, eleven surface deposit feeders, twelve (generalized) deposit feeders, and seven filter feeders. There are high numbers of the various filter-feeding mollusks such as Rangia cuneata and Crassostrea virginica. The important role of detritus and its associated microbial components is indicated by the predominance of the detritivore/omnivore fe
