Geographical variation in carbon stable isotope signatures of marine predators: a tool to investigate their foraging areas in the Southern Ocean

Stable carbon isotope signatures (δ13C) are increasingly being used to determine the foraging habitats of consumers in the Southern Ocean. An underlying assumption is that a latitudinal gradient in δ13C values at the base of the food chain should also be reflected in organisms at higher trophic leve...
