Range shifts are critical to species' persistence under climate change and are happening across the globe. Recent work has shownthat rapid evolution is a key driver of range expansion, prompting urgent calls to improve our understanding of eco-evolutionarydynamics in real-world range shifts. I will address this knowledge gap by applying my expertise in evolution during replicate invasionsin the lab to insect responses to climate change in the field. Modelling and landscape genetic tools have recently been developed bymy proposed supervisors and collaborators to account for complex genetic processes uniquely associated with rapid demographicand spatial expansion. With this combined expertise, we will conduct the first rigorous exploration of range shift evolutionaryprocesses and their repeatability along four parallel field transects in a rapidly poleward-expanding European insect (the damselflyIschnura elegans). My objectives are to (1) characterise clinal variation in dispersal phenotypes, fecundity, and climate adaptation inthe field, (2) evaluate the repeatability of genomic changes in adaptive, neutral and deleterious variation, and (3) determine howthese phenotypic and genotypic characteristics influence the rate and outcome of range expansions using a cutting-edge individualbased model. The results will (a) inform biodiversity management and blue-green infrastructure planning, and (b) fundamentallyadvance our understanding of the repeatability and predictability of eco-evolutionary dynamics, and the contribution of neutral,adaptive, or deleterious evolutionary processes during warming-induced range shifts. This research and host collaborative networkwill further establish me at the centre of major research hubs in range shift ecology and evolution, and will provide me with key skillsand opportunities in leadership, project management, mentoring, and outreach to ensure my independence as a future group leaderin Europe.

范围转移对于在气候变化下的物种持久性至关重要，并且正在全球发生。最近的工作已经显示出快速发展是范围扩展的关键驱动力，促使紧急呼吁我们在现实世界范围内的转变中对生态进化的人的理解。我将通过在复制实验室中的进化方面应用进化方面的专业知识来解决这一知识差距，以昆虫对田间气候变化的反应。最近，我提出的主管和合作者开发了建模和景观遗传工具，以解释与快速人口统计学和空间扩张唯一相关的复杂遗传过程。凭借这种综合的专业知识，我们将在快速扩展的欧洲昆虫（Damselflyischnura elegans）中对范围转移进化过程进行了第一次严格探索范围变化进化过程及其重复性。我的目标是（1）表征在该领域的分散表型，生育和气候适应性的clinal差异，（2）评估自适应，中性和多余的变化基因组变化的重复性，（3）确定Howthese表型和基因型特征使用范围扩展的范围扩展使用切割模型。结果将（a）为生物多样性管理和蓝绿色基础设施计划提供信息，以及（b）从根本上进行我们对生态进化动态的可重复性和可预测性的理解，以及在热范围诱导的范围转移过程中中性，适应性或有害进化过程的贡献。这项研究和主持协作网络将在范围转变生态和进化中进一步建立我在主要研究中心的中心，并将为我提供领导力，项目管理，指导和宣传方面的关键技能和机会，以确保我成为未来的集团领导者欧洲的独立性。
