Cross-generational plasticity in Atlantic silversides (Menidia menidia) under the combined effects of hypoxia and acidification.

ABSTRACT: We investigated the potential for cross-generational plasticity to influence how offspring respond to hypoxia and ocean acidification (hereafter HypOA) in the coastal forage fish Atlantic silverside (Menidia menidia). Mature wild silversides were treated with a control [dissolved oxygen (DO):100% air saturation (a.s.)/PCO2: 650 µatm] or HypOA (DO: 40% a.s./PCO2: 2300 µatm) conditions for 10 days prior to spawning. Their offspring were reared under both treatments in a factorial experimental design. Parental environment had minimal effects on offspring phenotype: exposure to HypOA reduced survival and developmental rates regardless of parental treatment. However, RNAseq analysis revealed that direct offspring exposure to HypOA induced substantial transcriptional changes, with 1606 different
