Data from: Age-specific offspring mortality economically tracks food abundance in a piscivorous seabird ...
Earlier offspring mortality prior to independence saves resources for kin, which should be more beneficial when food is short. Using 24 years of data on age-specific common tern (Sterna hirundo) chick mortality, best described by the Gompertz function, and estimates of energy consumption per age of...
