持续的气候变化，特别是与之相关的热浪，可能对生物多样性保护构成重大挑战。尽管温带地区的许多变温动物可能从当前的气候变化中受益，但其他动物将受到影响。然而，决定特定物种对气候变化的反应的具体生物学特征在很大程度上仍然未知。在本研究中，我们对三种铜蝴蝶进行了研究，这些铜蝴蝶对气候变化的脆弱性可能不同，我们使用生态真实的昼夜温度循环来测试它们对模拟热浪的反应。令人惊讶的是，我们发现几乎没有证据支持我们的假设，即最脆弱的物种将受到模拟气候变化的最大影响。尽管不同物种对处理的反应存在显著差异，但这种差异似乎主要受与特定发育途径相关的选择压力的支配。总的来说，模拟热浪对包括脂肪含量和免疫功能在内的健身成分几乎没有影响。因此，这三个物种似乎都有能力在它们的幼虫和蛹发育过程中处理预期的变化。这是否也适用于其他发展阶段，更极端的压力或气候变化的间接影响还有待观察。确定决定物种易受气候变化影响的关键因素仍将是未来研究的重要任务。
Ongoing climate change and especially the associated heat waves may pose a major challenge to biodiversity conservation. Although many ectotherms in temperate zones may benefit from current climate change, others will suffer. However, the specific biological features determining the response of a given species to climate change have remained largely unknown. In the present study, conducted in three copper butterfly species that likely differ in their vulnerability to climate change, we tested the responses to simulated heat waves using ecologically realistic diurnal temperature cycles. Surprisingly, we found little support for our hypothesis that the most vulnerable species will suffer most from simulated climate change. Although species differed significantly in their responses to treatments, such variation appears to be largely ruled by selection pressures associated with the specific developmental pathway. In general, simulated heat waves had little effect on fitness components including fat content and immune function. Consequently, all three species appear to be capable of dealing with projected changes during their larval and pupal development. Whether this also applies to other developmental stages, more extreme stress or indirect effects climate change remains to be seen. Identifying the critical factors determining the vulnerability of a species to climate change will remain an important task for future research.
