Eco-evolutionary dynamics of parallel climate-driven range shifts in the wild

在气候变化的情况下，物种生存范围的变化对物种的生存至关重要，而且这种变化正在地球仪上发生。最近的工作表明，快速进化是范围扩张的关键驱动力，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态的理解。我将通过运用我在实验室中的复制入侵过程中的进化专业知识来解决这个知识缺口，以实地昆虫对气候变化的反应。模型和景观遗传学工具最近已经由我建议的主管和合作者开发，以解释与快速人口和空间扩张唯一相关的复杂遗传过程。有了这些综合的专业知识，我们将进行第一次严格的探索范围转移evolutionaryprocesses和他们的重复性沿着四个平行的领域样带在一个迅速向极扩展的欧洲昆虫（豆娘Ischnura elegans）。我的目标是（1）在野外的扩散表型、繁殖力和气候适应性中的无性系变异，（2）评估适应性、中性和有害变异中基因组变化的可重复性，（3）确定这些表型和基因型特征如何影响分布区扩展的速率和结果，使用一个先进的基于个体的模型。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）从根本上推进我们对生态进化动力学的可重复性和可预测性的理解，以及在变暖引起的范围变化期间中性，适应性或有害进化过程的贡献。这个研究和主机协作网络将进一步建立我在主要研究中心的中心范围内转移生态学和进化，并将为我提供关键技能和机会，领导，项目管理，指导和推广，以确保我的独立性，作为未来的集团leaderin欧洲。

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.
