(a) Ontogenetic time series of proportional contribution of the different ecoregions to salmon shark vertebral tissue based on MixSIR using informative priors. Median (symbols), IQR (dashed lines) and 95% credible intervals (dotted lines) are shown. Priors were based on time spent in each ecoregion by satellite-tagged sharks and only used for ages 8+. (b) Time series of median proportional contribution of different ecoregions to salmon shark annuli (solid lines: informative priors, dotted lines: uninformative priors). (c) Cumulative proportional input of oceanic (median STG + SAGTZ) and neritic ecoregions (median AK + CA) (solid lines for ages 8+: informative priors, dotted lines for ages 8+: uninformative priors). Note that salmon sharks mature between 6 and 9 years of age [11].
