The Antarctic fur seal (Arctocephalus gazella) is a key marine predator in the Southern Ocean, a region that has recently started to show changes as a result of global climate change. Here, carbon (δ13C) and nitrogen (δ15N) stable isotope analyses on whole blood and plasma samples were used to exami...
