This project investigates the repeatability and thereby the predictability of adaptation to climate change by leveraging 1000 genomes sampled over 150 years and multiple climatic gradients in the rapidly adapting, globally invasive, and highly allergenic ragweed. We expect to deepen our understanding of the genetic basis of adaptation and decipher the circumstances under which adaptive genetic change is repeatable, by integrating a novel evolutionary model with genomic data. We will develop the capacity to predict species’ distributions and trait evolution under climate change using a powerful empirical dataset. This will provide us with the capacity to anticipate and manage the effects of climate change on noxious and threatened species.

该项目通过利用150多年来采样的1000个基因组和快速适应，全球入侵和高度过敏性的豚草中的多个气候梯度来研究适应气候变化的可重复性和可预测性。我们希望通过将一种新的进化模型与基因组数据相结合，加深我们对适应性遗传基础的理解，并破译适应性遗传变化可重复的情况。我们将开发预测气候变化下物种分布和性状进化的能力，使用强大的经验数据集。这将使我们有能力预测和管理气候变化对有毒和受威胁物种的影响。
