Chronic and acute thermal stressors have non-additive effects on fertility

Pilakouta N, Allan D, Moore E, Russell AA (2024)

We tested the independent and interactive effects of higher constant temperatures and short-term heatwave events on reproductive success. We found a substantial reduction in key fitness traits after exposure to both a heatwave and higher constant temperatures, but not after exposure to only one of these stressors. This indicates that the effects of chronic and acute thermal stressors are amplified when they act in combination. Our findings thus suggest that, by not considering the potential multiplicative effects of different thermal stressors, we may be underestimating the effects of climate change on animal fertility.
