  abstract = {{L}arge marine predators exhibit high concentrations of mercury ({H}g) as neumtoxic methylmercury, and the potential impacts of global change on {H}g contamination in these species remain highly debated. {C}urrent contaminant model predictions do not account for intraspecific variability in {H}g exposure and may fail to reflect the diversity of future {H}g levels among conspecific populations or individuals, especially for top predators displaying a wide range of ecological traits. {H}ere, we used {H}g isotopic compositions to show that {H}g exposure sources varied significantly between and within three populations of white sharks ({C}archarodon carcharias) with contrasting ecology: the north-eastern {P}acific, eastern {A}ustralasian, and south-western {A}ustralasian populations. {T}hrough {D}elta {H}g-200 signatures in shark tissues, we found that atmospheric {H}g deposition pathways to the marine environment differed between coastal and offshore habitats. {D}iscrepancies in delta {H}g-202 and {D}elta {H}g-199 signatures among white sharks provided evidence for intraspecific exposure to distinct sources of marine methylmercury, attributed to population and ontogenetic shifts in foraging habitat and prey composition. {W}e finally observed a strong divergence in {H}g accumulation rates between populations, leading to three times higher {H}g concentrations in large {A}ustralasian sharks compared to north-eastern {P}acific sharks, and likely due to different trophic strategies adopted by adult sharks across populations. {T}his study illustrates the variety of {H}g exposure sources and bioaccumulation patterns that can be found within a single species and suggests that intraspecific variability needs to be considered when assessing future trajectories of {H}g levels in marine predators.},
