...Mathieu Lutier; Fabrice Pernet; Vincent Vanaa; Carole Di Poi; Jérémy Le Luyer Ocean acidification occurs at a rate unprecedented for millions of years, forcing sessile organisms, such as oysters, to respond in the short term by relying on their phenotypic plasticity. Phenotypic plasticity has...

... to temperature, using 21 full-sibling larval families of the Pacific oyster, Crassostrea gigas . Pedigrees were confirmed with genetic markers for adult broodstock obtained from our breeding program. From these 21 larval families, 41 determinations of thermal sensitivity ( Q 10 values) were assayed for larvae...

..., a specific expressed sequence tag database from the Pacific oyster Crassostrea gigas , resulted in the identification of a receptor ( Cg -sNPFR-like) phylogenetically closely related to sNPF receptors (sNPFRs) of insects. A reverse endocrinology approach was undertaken to identify the peptide ligand(s...

...Rossana Sussarellu; Tony Dudognon; Caroline Fabioux; Philippe Soudant; Dario Moraga; Edouard Kraffe SUMMARY As oxygen concentrations in marine coastal habitats can fluctuate rapidly and drastically, sessile marine organisms such as the oyster Crassostrea gigas can experience marked and rapid oxygen...

... proteomic changes associated with exposure to elevated P CO 2 in the mantle tissue of eastern oysters ( Crassostrea virginica ) after 2 weeks of exposure to control (∼39 Pa P CO 2 ) and hypercapnic (∼357 Pa P CO 2 ) conditions using two-dimensional gel electrophoresis and tandem mass spectrometry. Exposure...

...Jean-Pierre Pennec; Hélène Talarmin; Mikaël Droguet; Marie-Agnès Giroux-Metgès; Maxime Gioux; Germaine Dorange SUMMARY Using the macro-patch clamp technique, we show that cardiac myocytes isolated from the heart of the oyster Crassostrea gigas possess several types of voltage-activated ionic...

...I. M. Sokolova; S. Evans; F. M. Hughes SUMMARY Exposure to environmentally prevalent heavy metals such as cadmium can have detrimental effects on a variety of commercially and ecologically important species such as oysters. Since Cd 2+ is known to induce apoptosis in immune cells of vertebrates, we...

...John N. Boyd; Louis E. Burnett ABSTRACT Oysters are frequently exposed to severely hypoxic conditions, especially during summer months. During the summer, there are also large numbers of disease-related oyster mortalities. This research was conducted to determine whether exposure to environmental...

...Kenneth A. Browne; Mario N. Tamburri; Richard K. Zimmer-Faust ABSTRACT Quantitative structure–activity relationships (QSARs) between the physicochemical properties of environmental signal molecules and animal behaviour have been determined. Past work has shown that oyster and barnacle larval...

...James S. Ballantyne; Christopher D. Moyes ABSTRACT Glutamate oxidation in mitochondria from the gills of oysters (Crassostrea virginica Gmelin) acclimated to sea water (SW) is sensitive to assay medium osmolantv. Compared to a medium of the osmolarity of sea water, decreasing osmolarity stimulates...
