Combating biodiversity declines is one of our greatest global challenges. Many migratory bird species are declining at rates far exceeding those of their resident counterparts. Impacts of chemicals on bird migration fitness has largely been ignored yet is important for international bird protection, and informing future UK policy to monitor and manage chemicals in the UK and effects abroad. Many birds feed in UK estuaries to fuel their global migrations where contaminants of environmental concern are often concentrated. Combining field sampling, empirical chemical measures, bird tracking, and modelling, this exciting project, supported by an internationally leading team of researchers at the universities of Exeter and York and policy advisors at the JNCC and Defra, will investigate the impact of contaminant exposures on wading bird migratory fitness. This project will develop new data and understanding on the risks of chemical exposure for selected estuary feeding wading birds (Dunlin, Curlew, Godwits and Oystercatchers) during critical life periods as they fuel for migration. Combining empirical studies and modelling approaches, the project will identify migratory wader species at higher risk(s) to chemical exposure effects for supporting more effective targeted future environmental protectionThe student will gain expertise in a wide range of scientific skills, including in ecotoxicology, ecology, analytical chemistry, modelling, bird handling and tagging, and advanced statistical methods. With stakeholder partners they will also gain in-depth knowledge in conservation biology, environmental monitoring, chemicals risk assessment, and domestic and international policy.

应对生物多样性下降是我们面临的最大全球挑战之一。许多候鸟物种的数量减少的速度远远超过了它们的本地同类。化学物质对鸟类迁徙适应性的影响在很大程度上被忽视了，但它对国际鸟类保护很重要，并为英国未来的政策提供了信息，以监测和管理英国境内的化学物质及其对国外的影响。许多鸟类在英国河口觅食，为它们的全球迁徙提供燃料，那里往往是环境污染的集中地。结合实地采样、经验化学测量、鸟类追踪和建模，这个激动人心的项目将由埃克塞特大学和约克大学的国际领先研究团队以及JNCC和Defra的政策顾问支持，研究污染物暴露对涉禽迁徙适应性的影响。该项目将开发新的数据，并了解在关键的生命时期，某些河口觅食的涉禽（Dunlin, Curlew， Godwits和Oystercatchers）在为迁徙提供燃料时暴露于化学物质的风险。结合实证研究和建模方法，该项目将确定受化学暴露影响风险较高的迁徙涉禽物种，以支持更有效的有针对性的未来环境保护。学生将获得广泛的科学技能的专业知识，包括生态毒理学，生态学，分析化学，建模，鸟类处理和标记，以及先进的统计方法。与利益相关者合作伙伴一起，他们还将获得有关保护生物学、环境监测、化学品风险评估以及国内和国际政策的深入知识。
