基　　金：Funding for GPS telemetry was provided by the International Crane Foundation, U.S. Forest Service, and the Paulson Institute. The animal capturing and marking permits were granted by the Ministry of Environment, Green Development, and Tourism of Mongolia to the Mongolian Wildlife Science and the Conservation Center. We thank Peter Mann for providing useful comments. We feel grateful to the European Space Agency (ESA) for providing the Sentinel-1 data. We finally thank the Sino-European joint research DRAGON 4 cooperation (ID. 32442. New Earth Observation Tools for Water Resource and Quality Monitoring in Yangtze Wetlands and Lakes) initiated within the ESA, MOST & NRSCC cooperation for initiating the collaboration.

摘　　要：Wetlands are among the most productive and essential ecosystems on earth,but they are also highly sensitive and vulnerable to climate change and human disturbance.One of the current scientific challenges is to integrate high-resolution remote sensing data of wetlands with wildlife movements,a task we achieve here for dynamic waterbird movements.We demonstrate that the White-naped cranes Antigone vipio wintering at Poyang Lake wetlands,southeast of China,mainly used the habitats created by the dramatic hydrological variations,i.e.seasonal water level fluctuation.Our data suggest that White-naped cranes tend to follow the water level recession process,keeping close to the boundary of water patches at most of the time.We also highlight the benefits of interdisciplinary approaches to gain a better understanding of wetland ecosystem complexity.
