“…If adaptive, non-genetic inheritance through environmentally induced parental effects might enable acclimation to persistent environmental changes, such as global warming (Donelan et al, 2020; Donelson, Salinas, Munday, & Shama, 2018). In a coral reef fish, the spiny chromis Acanthochromis polyacanthus (Bleeker 1855), for instance, studies have shown that parental developmental exposure to elevated temperature can provide transgenerational acclimation to ocean warming and restoration of aerobic scope in offspring through molecular changes in lipid and carbohydrate metabolism, as well as immune system and transcriptional regulation (Bernal, Ravasi, Rodgers, Munday, & Donelson, 2021; Bernal, Schmidt, Donelson, Munday, & Ravasi, 2022; Bonzi et al, 2023; Donelson, Munday, McCormick, & Pitcher, 2012; Ryu, Veilleux, Donelson, Munday, & Ravasi, 2018; Veilleux et al, 2015). The relative importance of fathers and mothers in such acclimation process, however, is unknown, but has implications on adaptive potential.…”
