Mean trophic level of marine mammals' consumption (<i>TL_Q</i>), Mean trophic level of fisheries' catches (<i>TL_C</i>), primary production required (<i>PPR</i>), and overlap indices (α<i>_j,l</i>) 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).
