Résumé

Phenological, biogeographic and community shifts are among the reported responses of marine ecosystems and their species to climate change. However, despite both the profound consequences for ecosystem functioning and ser- vices, our understanding of the root causes underlying these biological changes remains rudimentary. Here, we show that a significant proportion of the responses of species and communities to climate change are determinis- tic at some emergent spatio-temporal scales, enabling testable predictions and more accurate projections of future changes.We propose a theory based on the concept of the ecological niche to connect phenological, biogeographic and long-term community shifts. The theory explains approximately 70{%} of the phenological and biogeographic shifts of a key zooplankton Calanus finmarch- icus in the North Atlantic and approximately 56{%} of the long-term shifts in copepods observed in the North Sea during the period 1958–2009.
