Data from: Population density and climate shape early-life survival and recruitment in a long-lived pelagic seabird
1. Our understanding of demographic processes is mainly based on analyses of traits from the adult component of populations. Early-life demographic traits are poorly known mainly for methodological reasons. Yet, survival of juvenile and immature individuals is critical for the recruitment into the p...

Early-life demographic traits are poorly known mainly for methodological reasons.

The goal of this study was to estimate the early-life demographic parameters of a long-lived species with a long immature period (9–10 years), to test for sex and age effects on these parameters and to identify the environmental factors encountered during the period of immaturity that may influence survival and recruitment. 3. Using capture–mark–recapture multievent models allowing us to deal with uncertain and unobservable individual states, we analysed a long-term data set of wandering albatrosses to estimate both age- and sex-specific early-life survival and recruitment. We investigated environmental factors potentially driving these demographic traits using climatic and fisheries covariates and tested for density dependence. 4.

Early-life survival and recruitment were highly variable across years although the sensitivity of young birds to environmental variability decreased with age.

1. Our understanding of demographic processes is mainly based on analyses of traits from the adult component of populations. Early-life demographic traits are poorly known mainly for methodological reasons.
