Rapid environmental change currently presents a major threat to global biodiversity and ecosystem functions, and understanding impacts on individual populations is critical to creating reliable predictions and mitigation plans. One emerging tool for this goal is high-throughput sequencing technology, which can now be used to scan the genome for signs of environmental selection in any species and any system. This explosion of data provides a powerful new window into the molecular mechanisms of adaptation, and although there has been some success in using genomic data to predict responses to selection in fields such as agriculture, thus far genomic data are rarely integrated into predictive frameworks of future adaptation in natural populations. Here, we review both theoretical and empirical studies of adaptation to rapid environmental change, focusing on areas where genomic data are poised to contribute to our ability to estimate species and population persistence and adaptation. We advocate for the need to study and model evolutionary response architectures, which integrate spatial information, fitness estimates, and plasticity with genetic architecture. Understanding how these factors contribute to adaptive responses is essential in efforts to predict the responses of species and ecosystems to future environmental change.
当前,快速的环境变化对全球生物多样性和生态系统功能构成了重大威胁,而了解其对个体种群的影响对于制定可靠的预测和缓解计划至关重要。实现这一目标的一种新兴工具是高通量测序技术,该技术现在可用于扫描任何物种和任何系统的基因组,以寻找环境选择的迹象。这些数据的激增为适应的分子机制提供了一个强大的新窗口,尽管在利用基因组数据预测农业等领域对选择的反应方面已取得了一些成功,但迄今为止,基因组数据很少被纳入自然种群未来适应的预测框架。在此,我们回顾了适应快速环境变化的理论和实证研究,重点关注基因组数据有望有助于我们估计物种和种群持久性及适应性的领域。我们主张有必要研究和模拟进化反应架构,即将空间信息、适合度估计和可塑性与遗传架构整合起来。了解这些因素如何促成适应性反应,对于预测物种和生态系统对未来环境变化的反应至关重要。
