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...

We examined the effects of riverbed roughness and turbulence (shear velocity, ) on propagule dispersion in the near‐field region ( K x ) would match the patterns in roughness and . The Conestogo River had the highest downstream particle flux and K x as predicted by simple empirical equations. Inconsistent with model predictions, however, the Grand River had the lowest particle flux and K x . These differences were greater than...
