Figure 2. Ontogenetic changes in the isotopic niche of young female (orange) and male (light blue) Antarctic fur seals during the first 5 years of life.

The isotopic niche of full-size breeding females (dark red) and males (dark blue) are displayed for a better comparison. Each dot corresponds to a whisker segment, and solid lines to the SEAc of each group (on which percentage of niche overlap is calculated). Convex hull areas are represented in dotted lines, as a reference.
