Mean trophic level of marine mammals' consumption (TLQ), Mean trophic level of fisheries' catches (TLC), primary production required (PPR), and overlap indices (αj,l) for marine mammals and fisheries, and connectance in our study areas.

The overlap index scales from 0 (no overlap) to 0.250 (identical resource). Connectance is an index of ecosystem complexity that represents the proportion of possible links between groups that are realized (links/species2).
