Table S1. Reference database of the δ13C and δ15N values (‰) of the potential prey species of ringed seals from the three regions of Lake Saimaa.
Table S2. Pearson correlation estimates of observed stable isotope values of ringed seals in Lake Saimaa.
Table S3. Preplanned comparisons of the mean δ13C and δ15N values between pups and older (>1 yr) Saimaa ringed seals after analysis of variance. The overall repeated ANOVA result was highly significant (F = 5,515.2(7, 68.2) P < 0.001).
Table S4. Preplanned pairwise comparisons of the Saimaa ringed seal d15N and d13C values in different lake regions (N = northern, C = central, and S = southern) after ANOVA. The overall repeated ANOVA result was highly significant (F = 2,363.6(23,104.7), P < 0.001).
Table S5. Tukey's adjusted pairwise comparisons (all P-values were nonsignificant; P > 0.05) of d15N values of older (>1 yr) Saimaa ringed seals between seasons after ANOVA. The overall repeated ANOVA result was highly significant (F = 7.2(5, 25), P < 0.001).
Table S6. Tukey's adjusted pairwise comparisons of d15N values of Saimaa ringed seal pups between the time periods after ANOVA. The overall repeated ANOVA result was highly significant (F = 3.8(11, 47.3), P < 0.001).
