Population density and climate shape early-life survival and recruitment in a long-lived pelagic seabird
International audience 1. Our understanding of demographic processes is mainly based on analyses of traits fromthe adult component of populations. Early-life demographic traits are poorly known mainlyfor methodological reasons. Yet, survival of juvenile and immature individuals is critical forthe re...
