ABSTRACT Understanding how interactive environmental challenges affect marine species is critical to long‐term ecological and economic stability under global change. Marine calcifiers are thought be vulnerable ocean acidification (OA; elevated p CO 2 ); active dissolution of aragonite (Ω ar ) associated with disrupted development, survivorship, gene expression in bivalve larvae, resulting an early life‐stage bottleneck. Dynamic carbonate chemistry coastal systems emphasizes the importance multiple stressors, e.g., warming low salinity events may change organismal responses relative OA alone. We exposed Eastern oyster larvae ( Crassostrea virginica a full‐factorial experimental design using two temperatures (23°C 27°C), salinities (17 27), levels (~700 μatm 1850 ), Ω conditions 0.3–1.7. reduced by salinity, , temperature, each slowed development survival. Low × was linked severe undersaturation (< 0.5) that suppressed bicarbonate transport, biomineralization augmented for ciliary locomotion, proteostasis, histone modifiers.

Although shell growth survival were affected undersaturation, patterns D‐stage juveniles suggests tolerance dynamic estuarine environments. Genes confer postmetamorphosed oysters can improve our understanding environmental‐organismal interactions breeding programs enabling sustainable production.
