As long‐lived tropical trees grow into the multi‐layered canopy and face different environmental conditions, the relationships between leaf traits and whole‐plant survival can vary over ontogeny. We tested the strength and direction of the relationships between leaf traits and long‐term survival data across life stages for woody species from a subtropical forest in Puerto Rico. Trait–survival relationships were largely consistent across ontogeny with conservative traits leading to higher survival rates. The stage‐specific relationship R2 increased by up to one order of magnitude compared to studies not considering ontogenetic trait variations. Stage‐specific traits were significant predictors of their corresponding stage‐specific survival: Seedlings traits were better predictors of seedling survival than adult traits, and adult traits were better predictors of maximum adult survival than seedling traits. Our results suggest that stage‐specific leaf traits reflect different strategies over ontogeny and can substantially improve predictability of survival models in tropical forests.
