    “…We also perform the one-loop matching of gluon = and photon penguin operators onto operators of the HQET. We discuss applicati= ons of our results to the mixing of gluon and photon penguin operators at low renormalization scales, and to the calculation of $1/m_Q^2$ corrections t= o meson decays constants.…”

    Hybrid Renormalization of Penguins and Dimension-5 Heavy-Light Operators

    “…A total of seven main prey items were observed and consumed by little penguins. Penguins were observed to consume prey types and use strategies that have not been previously documented. …”

    Energetic consequences of prey type in little penguins (Eudyptula minor)
  3. 323
    “…We developed an automated method using depth and one axis of body acceleration data recorded by animal-borne data loggers to identify activities of penguins over long-term deployments. Using this technique, we evaluated the activity time budget of emperor penguins (n = 10) both in water and on sea ice during foraging trips in chick-rearing season. …”

    Activity Time Budget during Foraging Trips of Emperor Penguins

    “…In this study, we examined multiple tissues from Chinstrap penguins (Pygoscelis antarctica), collected in Antarctica during 2009 and 2010, for the presence of novel adenoviruses by PCR. …”

    “…Using 10 years of data (2000–2009) in a seasonally monogamous seabird, the king penguin (Aptenodytes patagonicus), we investigated the annual sex ratio at fledging, and the potential environmental causes for its variation. …”

    Inter-Annual Variability of Fledgling Sex Ratio in King Penguins

    “…We identified five species, three of which had not been described infecting penguins (P. cathemerium, P. nucleophilum, P. unalis); an additional five distinct Plasmodium lineages were also distinguished, and albeit unidentified these clearly correspond to species that also have not yet been reported in penguins. …”

    Epidemiology and pathology of avian malaria in penguins undergoing rehabilitation in Brazil
  7. 327
    “…BACKGROUND: Major, long-term environmental changes are projected in the Southern Ocean and these are likely to have impacts for marine predators such as the Adélie penguin (Pygoscelis adeliae). Decadal monitoring studies have provided insight into the short-term environmental sensitivities of Adélie penguin populations, particularly to sea ice changes. …”

    Proliferation of East Antarctic Adélie penguins in response to historical deglaciation
  8. 328
    “…Climate change impacts on penguins in the Antarctic will likely be highly site specific based on regional climate trends, and a southward contraction in the range of Adélie penguins is likely over the next century.…”

    “…The sense of smell, or olfaction, is fundamental in the life of animals. However, penguins (Aves: Sphenisciformes) possess relatively small olfactory bulbs compared with most other waterbirds such as Procellariiformes and Gaviiformes. …”

    “…We measured changes in the diving behaviour of 17 one-year-old king penguins Aptenodytes patagonicus at Crozet Islands (subantartic archipelago) during their first months at sea, using miniaturized tags that transmitted diving activity in real time. …”

    “…Animal vocalisations play a role in individual recognition and mate choice. In nesting penguins, acoustic variation in vocalisations originates from distinctiveness in the morphology of the vocal apparatus. …”
