The term 'sclerochronochemistry' (skleros--hard, chronos--time, and chemistry) is proposed here for complex twin studies of the
bivalve shell (and accretionary hard tissues of some other organisms, e.g., shells of gastropods, corals, fish otoliths): (1) characterization of growth history (i.e., sclerochronology s.s.), (2) identification and quantification of any impurities (i.e., organic, heavy metals, radionuclides, etc.) or isotopes (carbon, oxygen, nitrogen) in accordance with established successional growth patterns (Fig.
Utilization of detritus and bacteria as food sources by 2
bivalve suspension feeders, the oyster Crassostrea virginica and the mussel Geukensia demissa.
In our previous study, we evaluated the localization of a [beta]-integrin like protein ([beta]-integrin-LP) during the early development of the
bivalve M.
For example,
bivalve species with thicker shells were selected by larger predators, based on drill-hole diameter.
(2013), studying the distribution and density of the
bivalve A.
In Newport, Oregon, ARS ecologist Brett Dumbauld and collaborators are working to determine the impact of
bivalve aquaculture on estuary grasses and other habitats as well as on water quality.
Our assessment of the declines in
bivalve landings was undertaken to pursue one of the primary missions of NOAA's National Marine Fisheries Service: to understand how climate changes modify ecosystems and thus abundances and landings of commercial marine species.
Voultsiadou et al [57] reported that the early history of
bivalve mollusc exploitation and consumption in the Mediterranean coastal areas as recorded in the classical works of Greek antiquity.
However, these inorganic calcite crystals show consistent internal organization, with no evidence of the misorientations seen in most of the
bivalve prisms studied thus far (Checa et al., 2013).
As filter-feeders,
bivalves remove microscopic particulates from the water column, greatly enhancing water clarity and quality.
Through four days field trip, a team work of 6 persons collected gastropod and
bivalve shells from the intertidal zone of ten stations along Tarut coast, Arabian Gulf, Saudi Arabia (Fig.
