Climate change and functional traits affect population dynamics of a long-lived seabird
International audience 1.Recent studies unravelled the effect of climate changes on populations through their impact on functional traits and demographic rates in terrestrial and freshwater ecosystems, but such understanding in marine ecosystems remains incomplete.2.Here, we evaluate the impact of t...
