Consistent measures of oxidative balance predict survival but not reproduction in a long‐distance migrant
Abstract Physiological processes, including those that disrupt oxidative balance, have been proposed as key to understanding fundamental life‐history trade‐offs. Yet, examination of changes in oxidative balance within wild animals across time, space and major life‐history challenges remains uncommon...

Abstract Physiological processes, including those that disrupt oxidative balance, have been proposed as key to understanding fundamental life‐history trade‐offs. Yet, examination of changes in oxidative balance within wild animals across time, space and major life‐history challenges remains uncommon. For example, migration presents substantial physiological challenges for individuals, and data on migratory individuals would provide crucial context for exposing the importance of relationships between oxidative balance and fitness outcomes. Here we examined the consistency of commonly used measures of oxidative balance in longitudinally sampled free‐living individuals of a long‐lived, long‐distance migrant, the Brent goose Branta bernicla hrota over periods of months to years.
