Abstract A study of the calcareous tube-building polychaete Hydroides dianthus (Verrill) in a temperate estuary (Delaware Bay, USA) revealed an assemblage that was strongly associated with the serpulid. This polychaete species provided numerous microhabitats by means of its tubes and sediment enriched with tube fragments. Quantitative associations for winter and summer tube heads showed that 17 and 12 species, respectively, were statistically dependent on H. dianthus. There were significant associations between number of species, number of individuals, mean number of animals, standard deviation, the size of the tube clump for both seasons (winter and summer), and for scaled standard deviation (SDN) and species diversity (H) during the winter. Successional development of the serpulid assemblage starts with the settling of H. dianthus, progresses through growth, maturation, mortality, and the interaction of associates and predators, resulting in a highly diverse benthic assemblage in this temperate estuary.
