Life-history traits in the Pacific oyster Crassostrea gigas are robust to ocean acidification under two thermal regimes
Abstract Ocean acidification and warming (OAW) are pressing contemporary issues affecting marine life and specifically calcifying organisms. Here, we investigated the direct effects of OAW on life-history traits of the Pacific oyster Crassostrea gigas, the most cultivated bivalve species worldwide....

Abstract Ocean acidification and warming (OAW) are pressing contemporary issues affecting marine life and specifically calcifying organisms.

We also tested whether parental conditioning history shaped the phenotypic characters of their progenies (intergenerational carryover effects). Adult oysters and their offspring were exposed to two temperatures (18°C, +3°C) under ambient pH conditions or under an end-of-century acidification scenario (−0.33 pH unit).
