Identifying multi-scale exposure of anthropogenic threats to migratory birds

科学背景：由于人类活动引起的全球环境变化，生物多样性正在迅速减少。候鸟在近几十年来经历了大规模的人口下降，特别面临风险。确定候鸟死亡风险增加的地区是制定保护战略和制定适当缓解措施的关键。该项目将收集大斑雕（Aquila clanga）的新数据，并将联合收割机结合新的和现有的全球定位系统跟踪数据，对广泛的分类群进行跟踪，并结合从遥感数据集获得的环境变化威胁层，以确定迁徙路径上的威胁热点。研究结果将用于确定保护的优先领域，并建议缓解措施，以减少候鸟对人为威胁的暴露。研究方法：该项目将使用现有的GPS跟踪数据集为28个迁徙物种（从Movebank.org），并收集新的数据为重点模式物种（大斑点鹰），以审查非洲-古北区域的繁殖区、非繁殖区和迁徙路线受到人为威胁的情况。该项目将量化不同脆弱程度的鸟类暴露于各种威胁的时间，并将研究欧洲广泛计数数据（EBBA 2）与人口趋势的联系。对于选定的物种，将有可能检查繁殖成功指标，整体身体加速度信息和其他迁移能量消耗指标是否受到威胁的影响。

Scientific background: Biodiversity is rapidly declining in response to human induced global environmental change. Migratory birds are particularly at risk having experienced large population declines in recent decades. The identification of areas where migratory birds have increased mortality risks is key to inform conservation strategies and to develop appropriate mitigation measures. This project will collect new data for Greater Spotted Eagle (Aquila clanga) and will combine new and existing GPS tracking data, for a wide range of taxa, with environmental change threat layers, obtained from remote sensing datasets, to identify threat hotspots across migratory pathways. The results will be used to identify priority areas for conservation and to recommend mitigation measures that will reduce migratory birds' exposure to anthropogenic threats.Research Methodology: The project will use existing GPS tracking datasets for 28 migratory species (from Movebank.org) and gather new data for a focal model species (Greater Spotted Eagle), to examine exposure to anthropogenic threats across breeding, non-breeding areas and migratory routes in the Afro-Palearctic region. This project will quantify the time birds, with different levels of vulnerability, are exposed to a variety of threats and will examine links to population trends from European wide count data (EBBA2). For select species, it will be possible to examine if breeding success metrics, overall body acceleration information and other migration energy expenditure metrics are influenced by exposure to threats.
