Modeling Population Dynamics of Roseate Terns (Sterna dougallii) in the Northwest Atlantic Ocean

The endangered population of roseate terns (Sterna dougallii) in the Northwestern Atlantic Ocean consistsof a network of large and small breeding colonies on islands. This type of fragmented population poses anexceptional opportunity to investigate dispersal, a mechanism that is fundamental in popul...
