8) Loss of biogenic reef habitat, such as oyster and mussel beds, because of disease, overharvesting, other factors in this listing or unknown factors (Rothschild et al.
Biogenic reefs are created by living stone coral, Astrangia poculata, certain shellfishes (eastern oyster, Crassostrea virginica, and blue mussel, Mytilus edulis), and polychaete worms, such as Sabellaria vulgaris.
Eastern oysters, Crassostrea virginica, created biogenic reef habitat in estuarine and coastal ecosystems that was sustained by sequential recruitment, growth, and mortality (Mann et al.
ABSTRACT Oyster reefs support a valuable commercial fishery based on the extraction of oysters from the biogenic reef matrix they form.
Changes in populations of oysters and in the biogenic reefs that these ecosystem engineers create are predicted to have effects on surrounding community structure and ecosystem processes.
The study was mainly concerned with sea bed habitats such as sub-tidal sandbanks, invertebraterich sediments, biogenic reefs and those containing sea sponges, pink sea fans, and varieties of shellfish.
Biogenic reefs constructed by the Eastern oyster, Crassostrea virginica, provide complex, three-dimensional structural habitats in soft-sediment marine systems analogous to those provided by coral reefs (e.
Biogenic reefs that provide important ecosystem services such as habitat for other organisms include not only tropical coral reefs but also temperate reefs constructed by oysters (Bahr and Lanier, 1981; Lenihan et al.
ABSTRACT Increases in the frequency and duration of hypoxia and the loss of biogenic reefs are two of the most prominent environmental insults to estuaries.
