Climatic conditions produce contrasting influences on demographic traits in a long‐distance Arctic migrant
Summary The manner in which patterns of variation and interactions among demographic rates contribute to population growth rate (λ) is key to understanding how animal populations will respond to changing climatic conditions.

Summary The manner in which patterns of variation and interactions among demographic rates contribute to population growth rate (λ) is key to understanding how animal populations will respond to changing climatic conditions. Migratory species are likely to be particularly sensitive to climatic conditions as they experience a range of different environments throughout their annual cycle. However, few studies have provided fully integrated demographic analyses of migratory populations in response to changing climatic conditions. Here, we employed integrated population models to demonstrate that the environmental conditions experienced during a short but critical period play a central role in the demography of a long‐distance migrant, the light‐bellied Brent goose ( Branta bernicla hrota ). Female survival was positively associated with June North Atlantic Oscillation ( NAO ) values, whereas male survival was not.
