Interdecadal Variability in Biological Responses

What is the nature of the biological response in Eastern Boundary Currents to demonstrated, basin-scale, interdecadal changes in ocean-atmosphere coupling?

Among the uncertainties encompassed in these questions are: Do interdecadal shifts in climate lead to modification in timing or intensity of mesoscale activity which affects recruitment, retention/transport, predator-prey relationships, or life history strategies of plankton, nekton and benthic species? Are interdecadal shifts triggered by ENSO activity? How would a sustained (centennial-scale) global warming trend interact with natural interdecadal-scale ecosystem variability in the EBCs?
