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.

该项目研究了可重复性，从而通过利用150年的1000个基因组来适应气候变化的可预测性，并在快速适应中采样了多个气候梯度，全球侵入性且高度过敏性的毛weed。我们希望通过将新型进化模型与基因组数据相结合，可以加深对适应性遗传变化的遗传基础的理解。我们将使用强大的经验数据集在气候变化下预测物种分布和特质演变的能力。这将为我们提供预测和管理气候变化对有害和受威胁物种的影响的能力。
