Figure 1. Study area: harbor seal haul-out sites west off the Baja California peninsula, Mexico.Figure 2. δ15N and δ13C values (mean ± SD) of Pacific
harbor seal pup samples at different sites
along the west coast of the Baja California Peninsula (TSI=Todos Santos
Island, PBE= Punta Banda Estuary, SJI=San Jerónimo Island, NI=Natividad Island,
and SRI=San Roque Island).
Figure 3. δ15N and δ13C individual values of pup fur samples from Pacific harbor seals at five sampling sites
along the west coast of the Baja California Peninsula. Solid lines represent the
standard ellipses corrected for sample size (SEAc) and dashed lines represent
the convex hull areas.

Figure 4. SIAR density plot, with credibility intervals (50%
inside dark grey boxes, 75% middle grey boxes, 100% outer light grey boxes),
for the Bayesian generated ellipses (SEA; black dots) of the Pacific harbor
seal pup isotope data overlaid with sample size corrected for uncertainty
around the estimates (SEAc; red dots). Distribution in the standard ellipse
area (permill2) estimates are based on 106 resampling runs.
