Relative differences (%) reported as mean and 95% Confidence Intervals (CI) between climate change scenarios (i.e. RCP 2.6* and RCP 8.5**) relative to the baseline (i.e. no climate change control scenario) for the simulation period 2005–2099 in representative functional groups or/and species of the marine food web from the Northeastern Pacific.
