Isotopic niche plasticity in a marine top predator as indicator of a large marine ecosystem food web status

Isotopic niche plasticity in a marine top predator as indicator of a large marine ecosystem food web status

As marine ecosystems are harvested or modified by anthropogenic or natural factors, there is an increasing demand for indicators of trophic web health or status. The Magellanic Penguin (Spheniscus magellanicus) is a widely distributed species that forages in the Patagonian Shelf. During breeding, th...
