Marine heatwaves can have major and lasting effects on organism physiology species persistence. Such temperature extremes are increasing in frequency, with consecutive heatwave events already occurring within the lifetime of many organisms. Heat stress memory (thermal priming) by individuals is a potential within-generation response to cope recurring marine heatwaves. However, whether this form biological be inherited across generations not well known. We used three-generation experiment investigate individual transgenerational single fitness-related traits using stickleback (Gasterosteus aculeatus) as model species. exposed adults (both sexes) assessed female reproductive output both parent offspring generation, survival, growth behaviour establish holistic picture ectothermic fish. Exposure single, extreme lowered output, decreased exploratory behaviour, impeded capacity respond further thermal reduced long-term survival. prior experience (heat memory) mitigated some these at an (growth) (fecundity) level, indicating that experiencing frequency part ongoing climate change may better than previously thought.
