Polar bear (<i>Ursus maritimus</i>) data.

<p>a) QFASA estimates of marine mammal prey (Bearded seal <i>(Erignathus barbatus</i>), beluga whale (<i>Delphinapterus leucas</i>), harbour seal (<i>Phoca vitulina</i>), harp seal (<i>Pagophilus groenlandicus</i>), ringed seal (<i>Pusa hispida</i>) and walrus (<i>Odobenus rosmarus</i>)) consumed by individual polar bears (stacked coloured bars) and overlaid with H-Prints (black circles) of individual bears. Individual polar bears are grouped according to the geographical location of collection and the corresponding subpopulation designation: Baffin Bay, western Hudson Bay and southern Hudson Bay (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191631#pone.0191631.g002" target="_blank">Fig 2</a>). For each subpopulation, mean QFASA estimates of marine mammal prey and mean (black circles) and median (grey diamonds) H-Prints are summarised in the single plot adjacent to each subpopulation plot (for H-Print-derived estimates of sympagic carbon, refer to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191631#pone.0191631.t001" target="_blank">Table 1</a>). b) δ¹⁵N of individual bears (grey squares). For each subpopulation, mean δ¹⁵N are summarised in the single plot (box and whiskers) adjacent to each subpopulation plot.</p
