Long-term changes in habitat and trophic level of Southern Ocean squid in relat...
Abreu, José; Phillips, Richard A.; Ceia, Filipe R.; Ireland, Louise; Paiva, Vítor H.; Xavier, José C.Long-term studies of pelagic nekton in the Southern Ocean and their responses to ongoing environmental change are rare. Using stable isotope ratios measured in squid beaks recovered from diet samples of wandering albatrosses Diomedea exulans, we assessed decadal variation (from 1976 to 2016) in the habitat (δ13C) and trophic level (δ15N) of five important Southern Ocean squid species in relation to indices of e...
