Levy, Clucas, Rogers, Leaché, Ciborowski, Polito, Lynch, Dunn & Hart (in press). Population structure and phylogeography of the Gentoo Penguin (Pygoscelis papua) across the Scotia Arc. Ecol Evol. [abstract] [pdf]
Although currently classified as subspecies, the strong genetic differences in both nuclear and mitochondrial DNA of Northern and Southern Gentoo penguins may be indicative of incipient speciation similar to that of Rockhoppers. ... Further investigation of temporal, behavioral, and spatial barriers to breeding, as well as measures of adaptation to local environments, would be needed to delve into further taxonomic elucidation of the two Gentoo groups.
