Proportion of pups categorized as (A) Recently Fed/Phase I fasting, (B) Phase II, (C) Transitioning Phase II–III, and (D) Phase III for each subpopulation, organized from the northwestern to northeastern Pacific Ocean. Subpopulations significantly different from others within each fasting category are denoted by lowercase letters. Note, the y-axis in (A, range 0.0–1.0) is different than that shown for (B), (C), and (D) with range 0.0–0.3. Sum of proportions for each subpopulation in (A), (B), (C), and (D) sums to 1.
