Animal migrations are extensive, ubiquitous, and in decline. To effectively protect migratory species, it is often crucial to identify the interconnected sets of sites they rely upon. Gaps between primary ecological research and synthesised information that is useful to policymakers has limited effective conservation of long-distance migrants, particularly in the marine realm. By synthesising 1304 references to identify 1787 sites and develop model migratory networks for 109 species, we show the minimum extent of marine megafauna connectivity across the global oceans. Our analyses underscore the importance of transboundary cooperation for migratory species conservation at scales larger than current regional structures afford and provide a free online system that will enable policymakers to efficiently summarise how marine migrants use and connect their jurisdictions.
动物迁徙范围广泛、普遍存在且数量正在减少。为了有效保护迁徙物种，识别它们所依赖的相互关联的地点集合通常至关重要。基础生态研究与对政策制定者有用的综合信息之间的差距，限制了对长途迁徙者的有效保护，尤其是在海洋领域。通过综合1304篇参考文献来识别1787个地点，并为109个物种建立迁徙网络模型，我们展示了全球海洋中海洋大型动物连通性的最小范围。我们的分析强调了跨界合作对于迁徙物种保护的重要性，其规模大于当前区域结构所能提供的范围，并提供了一个免费的在线系统，使政策制定者能够有效地总结海洋迁徙者如何利用和连接其管辖区域。
