Fig. 4

Principal coordinates analysis (PCO) plot derived from the dietary composition of Pacific cod (Gadus macrocephalus). The vectors are plotted to illustrate the strength and direction of the correlations of prey taxa among site, season, and size relative to the PCO axes, with the cycle indicating a correlation of 1. Shaded polygon areas indicate the convex hulls of total area for the eight feeding groups.
