Animal movements contribute to the spread of infectious diseases and are driven in part by environmental conditions. We investigated the links among the environment, animal movement, and infectious disease dynamics in waterfowl, which are among the primary wildlife hosts of avian influenza viruses. By combining telemetry data on 4606 individuals from 26 waterfowl species with data on land cover, weather, and vegetation, we fou...

Few studies have explored population dynamics of species sharing life-history traits and common environmental drivers but living in widely separated regions or continents. Large-scale climate cycles can impact habitats and populations over broad geographic areas and may act as global forces shaping animal population dynamics. We tested for synchronous population dynamics of eight ecologically equivalent duck species in Western...
