Age‐related reproductive performance of the Adélie penguin, a long‐lived seabird exhibiting similar outcomes regardless of individual life‐history strategy
Abstract Age‐related variation in reproductive performance in long‐lived iteroparous vertebrate species is common, with performance being influenced by within‐individual processes, such as improvement and senescence, in combination with among‐individual processes, such as selective appearance and di...
