The article presents a study which examines the ecological niche separation of Risso's dolphin Grampus Griseus in the southwestern South Atlantic Ocean. The study investigates bone collagen from 48 Grampus individuals in Tierra del Fuego, Argentina through stable isotope analysis (SIA). The study reveals changes in baseline isotope values of the food web, foraging habitats from inshore to offshore areas, and north to south latitudinal shift in foraging grounds. |
