A review of historical and contemporary processes affecting population genetic structure of Southern Ocean seabirds

KJ Munro, TM Burg - Emu-Austral Ornithology, 2017 - Taylor & Francis

Sex‐biased survival contributes to population decline in a long‐lived seabird, the Magellanic Penguin

NJ Gownaris, PD Boersma - Ecological Applications, 2019 - Wiley Online Library
Abstract We developed a Hidden Markov mark–recapture model (R package marked) to
examine sex‐specific demography in Magellanic Penguins (Spheniscus magellanicus). Our …

Marked phylogeographic structure of Gentoo penguin reveals an ongoing diversification process along the Southern Ocean

JA Vianna, D Noll, GPM Dantas, MV Petry… - Molecular Phylogenetics …, 2017 - Elsevier

Population regulation in Magellanic penguins: what determines changes in colony size?

LM Pozzi, PG Borboroglu, PD Boersma, MA Pascual - PLoS One, 2015 - journals.plos.org
Seabirds are often studied at individual colonies, but the confounding effects of emigration
and mortality processes in open populations may lead to inappropriate conclusions on the …
