A global of key nodes in migratory bird networks potentially linked to influenza A virus spread

候鸟在甲型流感病毒 （IAV） 的远距离传播中发挥着重要作用，对人类健康和畜牧生产安全构成潜在威胁。然而，关于 IAV 相关候鸟迁徙网络的综合数据集仍然稀缺，从而阻碍了病毒传播风险的评估和有效防控策略的制定。在这项研究中，我们通过整合基于文献的数据和 Movebank 跟踪记录开发了一个全面的数据集，重点关注与 IAV 相关的候鸟迁徙网络中的关键节点。该数据集涵盖了与 IAV 相关的 101 种候鸟的 10,088 条迁徙路线记录。使用 ArcGIS 和 Gephi 工具，我们计算了迁移网络中每个节点的中介中心性值，以量化它们在网络中的重要性并确定关键节点。该数据集将作为分析候鸟网络、评估 IAV 传播风险和制定生态保护策略的宝贵资源。

Migratory birds play a critical role in the long-distance transmission of influenza A virus (IAV), posing potential threats to human health and the safety of livestock production. However, comprehensive datasets focused on the migratory networks of IAV-associated migratory birds remain scarce, which hinders the assessment of viral transmission risks and the development of effective prevention and control strategies. In this study, we developed a comprehensive dataset by integrating literature-based data and Movebank tracking records, with a focus on key nodes in the migratory networks of IAV-associated migratory birds. This dataset contains 10,088 migratory route records covering 101 species of IAV-associated migratory birds. Using ArcGIS and Gephi tools, we calculated the betweenness centrality values of each node in the migratory networks to quantify their importance in the networks and identify key nodes. This dataset will serve as a valuable resource for analyzing migratory bird networks, assessing IAV transmission risks, and formulating ecological conservation strategies.
