Fig. 4: Seabird prey portfolios.
From: Ecosystems mediate climate impacts on northern hemisphere seabirds
Portfolios are ordered left to right by increasing diversity score (Shannon-Wiener Index) shown as H’ values along with the number of seabird species at top. Bars show the proportion of seabirds using each prey item across ecosystems. Color-coding displays coarse prey groups, white outlines indicate particular prey taxa within the group (see Methods and Supplementary Table 3).
