... of an intertidal temperate oyster, Crassostrea gigas , reusing data from a previous study. Despite showing similar tipping points to C. gigas , P. margaritifera exhibits strong mortality and depletion of energy reserves below these tipping points, which is not the case for C. gigas . This divergence relies mainly...

... understood. In this study of developmental stages of the Pacific oyster, Crassostrea gigas , thermal sensitivities were measured for growth, survivorship, protein synthesis, respiration and transport of amino acids and ions. At warmer temperatures, larvae grew faster but suffered increased mortality...

..., 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...

...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...

... tested in the oyster Crassostrea gigas and the clam Ruditapes philippinarum . Oysters and clams were fed each of three cultured algae: Chaetoceros calcitrans , which is rich in 20:5(n-3) and 20:4(n-6) and poor in 22:6(n-3) fatty acids; T- Iso ( Isochrysis sp.), which is rich in 22:6(n-3) and deficient...

... to determine how these hormones participate in the organisation of neuroendocrine stress-response axes in invertebrates. Our present work provides evidence for the presence of an adrenergic stress-response system in the oyster Crassostrea gigas . Noradrenaline and dopamine are released into the circulation...

... of metabolic rates were made with the coulometric respirometer during the complete life-span of larvae of three species (asteroid, Asterina miniata ; bivalve, Crassostrea gigas ; echinoid, Dendraster excentricus ). For these species, metabolic power equations had mass exponents near unity (0.9–1.1), showing...
