A study of yellow warblers identifies genomic regions involved in climate change adaptation Human-induced climate change is causing rapidly changing global temperatures and extreme fluctuations in precipitation. These changes force organisms to adapt and evolve or face extinction. Understanding and predicting the evolutionary responses to climate change is critical for preserving biodiversity, but predictions are challenging because they involve interactions between adaptive plasticity (such as altered breeding times) and evolved responses (such as increased metabolism). On page 83 of this issue, Bay et al. (1) combine high-resolution genomic sequencing with population trends and global climate predictions to estimate the adaptive potential (that is, the genetic variation necessary for adaptation) of yellow warblers (see the photo) to climate change and predict future population declines. In doing so, they produce a powerful tool for estimating genomic vulnerability to climate change and locate candidate genes that are key for climate change adaptation.

气候变化的基因组学

对黄莺的研究确定了参与气候变化适应的基因组区域 人为引起的气候变化正在导致全球气温迅速变化和降水的极端波动。这些变化迫使生物体适应和进化或面临灭绝。了解和预测对气候变化的进化反应对于保护生物多样性至关重要，但预测具有挑战性，因为它们涉及适应性可塑性（例如改变繁殖时间）和进化反应（例如新陈代谢增加）之间的相互作用。在本期第 83 页，Bay 等人。(1) 将高分辨率基因组测序与人口趋势和全球气候预测相结合，以估计适应潜力（即，黄莺（见图）适应气候变化和预测未来种群数量下降所需的遗传变异。在这样做时，他们产生了一个强大的工具来估计基因组对气候变化的脆弱性，并定位对气候变化适应至关重要的候选基因。
