  abstract = {{T}his work aimed to provide a better understanding of how the structure and function of marine ecosystems and trophic control mechanisms influence their response to perturbations. {C}omparative analysis of {E}copath models of four {N}ortheast {A}tlantic ecosystems was used to search for rules of thumb defining the similarities and differences between them. {E}cosystem indicators, related to the ecology of species interactions, were derived from these models and compared. {T}wo main questions were addressed. (i) {W}hat are the main energy pathways and mechanisms of control? (ii) {D}o these ecosystems exhibit the widespread and potentially stabilizing food-web structure such that top predators couple distinct energy pathways? {A} strong bentho-pelagic coupling operated over the {B}ay of {B}iscay {S}helf, while energy reached higher trophic levels mostly through pelagic compartments, in northern areas. {Z}ooplankton was demonstrated to be trophically important in all ecosystems, acting as a regulator of the abundance of small pelagic fish. {A} latitudinal pattern in flow control was highlighted by this analysis, with a significant contribution of top-down effect at higher latitudes. {T}his top-down control of the {B}altic {S}ea, combined with the fact that this ecosystem did not exhibit the potentially stabilizing two-channel structure, suggested a non-stable environment.},
