Abstract Extreme temperature events, such as heat waves, can have lasting effects on the behavior, physiology, and reproductive success of organisms. Here, we examine impact short-term exposure to a simulated wave condition, parental care, in population threespine stickleback (Gasterosteus aculeatus), small fish with exclusive paternal currently experiencing regular waves. Males were either exposed (23 °C) for 5 d or held at an ideal (18 °C). Following this 5-d treatment, all males transferred 18 °C, where they completed full parenting cycle. Offspring raised °C. We found that while mass body condition unaffected wave, cortisol responses dampened across nesting cycle compared control males. In addition, had longer latency eggs hatch, lower hatching success, showed levels care behavior affecting swimming performance. Altogether, our results highlight long-term even events subsequent generations, providing insight into rapid environmental change.
