  1. The ecstatic display call of the Adélie penguin (Pygoscelis adeliae)

    Marks, Emma JosephineResearchSpace@Auckland2006

    … of study for many years. The Adélie penguin (Pygoscelis adeliae) breeds in vocally challenging Antarctic colonies and has evolved a complex system of intra- and intersexual visual and vocal behaviours. Unique to the Adélie penguin, is the presence of two distinct display calls, the Loud Mutual …

    Ross, Lori Lea1997

    … an experiment on free-living Adélie penguins (Pygoscelis adeliae), an offshore feeding seabird with biparental care of semi-altricial young which breeds in the harsh environment of Antarctica. We also measured prolactin levels in male Adélie penguins that lost their eggs during incubation. The …

    … (Phalacrocorax verrucosus) and gentoo penguins (Pygoscelis papua) breeding on Kerguelen Island, showed genetic structure among different breeding colonies of each species on the same island. Non-physical barriers such as natal philopatry and at-sea distribution, are limiting gene flow in the …

  8. Remote sensing of penguin populations: Development and application of a satellite-based method

    Brown, Jennifer AnneUniversity of Cambridge2018

    Five penguin species breed in Antarctica: emperors, Adélies, chinstraps, gentoos and macaronis. These are important Antarctic mid-trophic level predators and under predicted climate change are believed threatened. Accurate monitoring of populations is therefore of growing importance owing to the …
