Isotopic insights into mesopelagic niche space and energy pathways on the southern Kerguelen Plateau

Mesopelagic fish are an important but poorly understood mid-trophic component of pelagic food webs. There are major uncertainties regarding their trophodynamics and their overall contribution to the broader Southern Ocean food web. This study aimed to investigate the trophic role of mesopelagic fish in the region of the southern Kerguelen Plateau, an area of known importance to an abundant and diverse community of marine predators. We used...
