北极正在进入一种新的生态状态，对人类造成令人担忧的后果。动物身上的传感器提供了一个了解这些变化的窗口。虽然存在大量来自北极和亚北极的动物跟踪数据，但大多数都很难发现和获取。在这里，我们介绍了新的北极动物运动档案（AAMA），从1991年到现在，200多个标准化的陆地和海洋动物跟踪研究的不断增长的集合。AAMA支持公共数据发现，为未来保留基础基线数据，并促进高效的协作数据分析。通过基于AAMA的案例研究，我们记录了气候对鹰的迁徙物候的影响，驯鹿生殖物候对气候变化的适应性反应的地理差异，以及陆地哺乳动物运动速率对温度升高的响应的物种特异性变化。
The Arctic is entering a new ecological state, with alarming consequences for humanity. Animal-borne sensors offer a window into these changes. Although substantial animal tracking data from the Arctic and subarctic exist, most are difficult to discover and access. Here, we present the new Arctic Animal Movement Archive (AAMA), a growing collection of more than 200 standardized terrestrial and marine animal tracking studies from 1991 to the present. The AAMA supports public data discovery, preserves fundamental baseline data for the future, and facilitates efficient, collaborative data analysis. With AAMA-based case studies, we document climatic influences on the migration phenology of eagles, geographic differences in the adaptive response of caribou reproductive phenology to climate change, and species- specific changes in terrestrial mammal movement rates in response to increasing temperature.
