Microalgal cell surface carbohydrates as recognition sites for particle sorting in suspension-feeding bivalves.
Cell surface carbohydrates play important roles in cell recognition mechanisms. Recently, we provided evidence that particle selection by suspension-feeding bivalves can be mediated by interactions between carbohydrates associated with the particle surface and lectins present in mucus covering bivalve feeding organs. In this study, we used lectins tagged with fluorescein isothiocyanate (FITC) t...
متن کاملFacilitation of seagrass Zostera marina productivity by suspension-feeding bivalves
Seagrasses and suspension feeders are both critical ecosystem engineers in estuaries. Seagrass beds are important structural habitats, and suspension feeders, when abundant, can regulate phytoplankton densities. Furthermore, there may be mutual facilitation of growth and recruitment between seagrasses and suspension-feeding bivalves. In a series of mesocosm experiments, the effects of environme...
متن کاملParticle capture mechanisms in suspension-feeding invertebrates
A large number of suspension-feeding aquatic animals (e.g. bivalves, polychaetes, ascidians, bryozoans, crustaceans, sponges, echinoderms, cnidarians) have specialized in grazing on not only the 2 to 200 μm phytoplankton but frequently also the 0.5 to 2 μm free-living bacteria, or they have specialized in capturing larger prey, e.g. zooplankton organisms. We review the different particle captur...
متن کاملModeling 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 کاملComparison of Gill Surface Morphology across a Guild of Suspension-feeding Unionid Bivalves
Freshwater mussels are found in dense, multi-species aggregations where the potential for resource partitioning should be high. One means by which mussels may be partitioning resources is through feeding on different food items. We compared gill morphology in four species of co-occurring freshwater mussels. We found differences in total gill surface area, density of latero-frontal cirri and the...
