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.
