Modeling food choice in the two suspension‐feeding bivalves, Crassostrea virginica and Mytilus edulis
In marine ecosystems, benthic invertebrates contribute to many ecological functions, including the regulation of energy fluxes. This is the case for suspension-feeding organisms that often dominate the macrobenthos in coastal areas. Dense populations of benthic filter-feeders interact strongly with nearshore waters, removing phytoplankton, producing biodeposits, and cycling dissolved nutrients ...
متن کاملFood sources of the infaunal suspension-feeding bivalve Cerastoderma edule in a muddy sandflat of Marennes-OlQon Bay, as determined by analyses of carbon and nitrogen stable isotopes
Stable carbon and nitrogen isotope ratios were used to define the trophic base of the infaunal suspension-feeding bivalve Cerastoderma edule (L.) living on an intertidal muddy sandflat in Marennes-Oleron Bay, France. Suspended particulate organic matter (POM) collected from adjacent marine channels had a mean 6I3C value of -22 2 * 1.1 %O (n = 19). Benthic primary producers on Ronceles-Bains tid...
متن کاملCharacterization of the mantle transcriptome in bivalves: Pecten maximus, Mytilus edulis and Crassostrea gigas.
The calcareous shells secreted by bivalve molluscs display diverse and species specific structural compositions, which indicates possible divergent biomineralization processes. Thus, studying multiple mollusc species will provide a more comprehensive understanding of shell formation. Here, the transcriptomes of the mantle tissues responsible for shell deposition were characterized in three comm...
متن کاملMultixenobiotic resistance protein expression in Mytilus edulis, M. galloprovincialis and Crassostrea gigas from the French coasts
Multixenobiotic resistance (MXR) is a membrane-transport mechanism that allows organisms to exclude many compounds from their cells and tissues. It is thus a first line of defence against a variety of toxic compounds. Since mussels and oysters possess MXR proteins, an analysis of the expression level of these membrane-transporters has been conducted in relation to their body burden of some majo...
متن کاملInfluence of diet on pre-ingestive particle processing in bivalves I: Transport velocities on the ctenidium
Suspension-feeding bivalve molluscs can assume a large ecological role by linking benthic and pelagic ecosystems. Therefore, a knowledge of the factors that influence feeding rates and processes at the level of the individual is important in understanding bivalve-dominated environments. We examined the roles of diet quality and concentration on particle processing by the ctenidia of four specie...
