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

点击翻译按钮获取中文摘要

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.
