	abstract = {<p>Climate variability across three distinct spatial scales and the  interannual changes of planktonic copepods and jellyfish were studied  from November 1966 to December 1993. The results obtained identified a  cascade of linksbetween the large-scale climate pattern playing out in  the North Atlantic and the local climate variability governingthe  Ligurian Sea, northwestern Mediterranean. The chain of events appeared  driven by the long-term  temperature anomalies that in turn played a key  role in the relationship between copepods and jellyfish. Indeed, the  increase in jellyfish outbreaks during the 1980s was largely favored by  high positive anomalies observed in climate at large (North Atlantic),  regional (Ligurian Sea), and local (Villefranche Bay) spatial scales and  in water temperature. Linked to jellyfish abundance, the dynamics of  the relationship between copepods and jellyfish showed a strong  modification during the middle-late 1980s, which highlight the top-down  effect exerted by jellyfish on copepods. The warming temperatures and  the observed ecological changes, high abundance of jellyfish, and marked  drop in the abundance of copepods are discussed in the framework of a  potential change in the functioning of the planktonic ecosystem  indicative of a more regeneration-dominated production system in the  Ligurian Sea. Overall, the cascade of links identified by these results  should be considered and integrated into the assessment and modeling  studies of pelagic ecosystem and biogeochemical fluxes in the  northwestern Mediterranean Sea.</p>},
