Community-wide measures of rockfish trophic structure compared between the MPA and each fished area (North and South).

Total area (TA) of the convex hulls represents the total niche space occupied and thus total extent of trophic diversity in the food web. Nitrogen range (NR) represents the vertical structure within a food web, and carbon range (CR) represents the range in basal resources at the base of a food web. Mean distance to centroid (CD) provides an average measure of trophic diversity and is a function of species spacing. Probability (%) of difference in niche metrics were calculated with Eq 2.
