Data from: Population structure and phylogeography of the Gentoo Penguin (Pygoscelis papua) across the Scotia Arc
Climate change, fisheries pressure on penguin prey, and direct human disturbance of wildlife have all been implicated in causing large shifts in the abundance and distribution of penguins in the Southern Ocean. Without mark-recapture studies, understanding how colonies form and, by extension, how ra...

Climate change, fisheries pressure on penguin prey, and direct human disturbance of wildlife have all been implicated in causing large shifts in the abundance and distribution of penguins in the Southern Ocean.
