人为气候变化引起的热应激增加可能对生物多样性构成重大挑战，因为其对生存和繁殖产生不利影响。因此，耐热性最近受到了极大的关注，但其在整个个体发育中的变化以及从一个发育阶段到另一个发育阶段的影响仍然在很大程度上被忽视。要探讨在何种程度上经历的压力在生命早期影响以后的生活阶段，我们在这里调查的影响，在整个个体发育的热带蝴蝶Bicyclus anynana在卵阶段经历的热应力。我们发现，在卵期热应激的有害影响是可检测到的孵化，幼虫，甚至由此产生的成年人，证明了减少生存，生长和体重。这项研究表明，即使是在具有离散生命阶段的全变态昆虫中，在生命早期经历的压力的影响也会延续到后期阶段，大大降低随后的适应性。我们认为，在试图预测物种对气候变化的反应时，需要考虑这种影响。
Increasing heat stress caused by anthropogenic climate change may pose a substantial challenge to biodiversity due to associated detrimental effects on survival and reproduction. Therefore, heat tolerance has recently received substantial attention, but its variation throughout ontogeny and effects carried over from one developmental stage to another remained largely neglected. To explore to what extent stress experienced early in life affects later life stages, we here investigate effects of heat stress experienced in the egg stage throughout ontogeny in the tropical butterfly Bicyclus anynana. We found that detrimental effects of heat stress in the egg stage were detectable in hatchlings, larvae and even resulting adults, as evidenced by decreased survival, growth, and body mass. This study shows that even in holometabalous insects with discrete life stages effects of stress experienced early in life are carried over to later stages, substantially reducing subsequent fitness. We argue that such effects need to be considered when trying to forecast species responses to climate change.
