At-sea ecology of the Emperor penguin (Aptenodytes forsteri) : Foraging strategies and evaluation of methodological and conservation tools

Iconic species used to raise public awareness, the Emperor penguin is first and foremost a top predator and umbrella species playing a pivotal role in Antarctic ecosystems. Standing at the forefront of climate upheavals, much remains to be learned about the ecology, distribution, and activities at s...
