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.

分布范围的变化对于物种在气候变化下的生存至关重要，并且这种变化正在全球范围内发生。最近的研究表明，快速进化是范围扩大的关键驱动因素，这促使人们迫切呼吁提高我们对现实世界范围变化中生态进化动力学的理解。我将通过在实验室复制入侵过程中运用我在进化方面的专业知识来解决这一知识差距，以解决昆虫对实地气候变化的反应。我提议的主管和合作者最近开发了建模和景观遗传工具，以解释与人口和空间快速扩张独特相关的复杂遗传过程。凭借这些综合专业知识，我们将首次严格探索范围转移进化过程及其沿着快速向极地扩张的欧洲昆虫（豆娘Ischnura elegans）的四个平行场样带的可重复性。我的目标是（1）表征现场传播表型、繁殖力和气候适应的临床变异，（2）评估适应性、中性和有害变异中基因组变化的可重复性，以及（3）确定这些表型和基因型特征如何影响使用尖端的基于个人的模型进行范围扩展的速度和结果。研究结果将（a）为生物多样性管理和蓝绿基础设施规划提供信息，（b）从根本上增进我们对生态进化动力学的可重复性和可预测性，以及变暖引起的中性、适应性或有害进化过程的贡献的理解范围变化。这个研究和主办合作网络将进一步使我成为范围转变生态学和进化领域主要研究中心的中心，并将为我提供领导力、项目管理、指导和外展方面的关键技能和机会，以确保我作为未来小组领导者的独立性。欧洲。
