Age‐related variation in reproductive traits in the wandering albatross: evidence for terminal improvement following senescence
Abstract The processes driving age‐related variation in demographic rates are central to understanding population and evolutionary ecology. An increasing number of studies in wild vertebrates find evidence for improvements in reproductive performance traits in early adulthood, followed by senescent...

Abstract The processes driving age‐related variation in demographic rates are central to understanding population and evolutionary ecology.
