Trophic ecology of northern gannets Morus bassanus highlights the extent of isotopic niche overlap with other apex predators within the Bay of Biscay

Understanding the linkages within complex and evolving marine food webs is essential to comprehend marine ecosystem structure and dynamics. Carbon (δ 13 C) and nitrogen (δ 15 N) stable isotope signatures are recognized to be powerful descriptors of the trophic ecology and trophic relationships withi...
