Data from: Sex-specific patterns of reproductive senescence in a long-lived reintroduced raptor
1) For many species there is evidence that breeding performance changes as an individual ages. In iteroparous species, breeding performance often increases through early-life and is expected to level out or even decline (senesce) later in life. Furthermore, an individual's sex and conditions ex...
