Animals, 2019 Simple Summary Some studies on zoo penguins have shown that the presence of visitors may be fear-provoking. To manage zoo visitor–animal interactions, it is important to determine what it is about visitors that affects zoo penguins.

New Physics and Enhanced Gluonic Penguin [PDF]
, 1997 We discuss the historical development of the gluonic B-penguin, its sensitivity to $H^+$ effects, and $\bsg\sim$ 10--15% as a possible solution to the $\Bsl$ and $n_C$ problems. The latter and the connection of the gluonic penguin to inclusive $B\to \eta^

Mitogenomes Uncover Extinct Penguin Taxa and Reveal Island Formation as a Key Driver of Speciation.
Molecular biology and evolution, 2019 The emergence of islands has been linked to spectacular radiations of diverse organisms. Although penguins spend much of their lives at sea, they rely on land for nesting, and a high proportion of extant species are endemic to geologically young islands.

Drones, 2019 Antarctic marine ecosystems undergo enormous changes, presumably due to climate change and fishery. Unmanned aerial vehicles (UAVs) have an unprecedented potential for measuring these changes by mapping indicator species such as penguins even in remote ...

Charming penguin and direct CP-violation in charmless B decays
, 2002 In the study of two-body charmless B decays as a mean of looking for direct CP-violation and measuring the CKM mixing parameters in the Standard Model, the short-distance penguin contribution with its absorptive part generated by charm quark loop seems ...

Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance We reveal species-specific changes in penguin trophic responses to historic shifts in krill availability over the last century by applying new molecular isotope techniques to historic penguin museum specimens.

Frontiers in Marine Science, 2021 Many remote islands present barriers to effective wildlife monitoring in terms of challenging terrain and frequency of visits. The sub-Antarctic islands of South Georgia and the South Sandwich Islands are home to globally significant populations of ...

Quark- and Gluon-Condensate Contributions to Penguin Four-Fermi Operators [PDF]
, 1999 The nonperturbative content of the QCD vacuum permits the occurrence of QCD-vaccum condensate contributions to penguin amplitudes. We calculate the dimension-4 $$ and $$ contributions to the effective Wilson coefficients for penguin four-Fermi operators,

Multi-modal survey of Adélie penguin mega-colonies reveals the Danger Islands as a seabird hotspot
Scientific Reports, 2018 Despite concerted international effort to track and interpret shifts in the abundance and distribution of Adélie penguins, large populations continue to be identified. Here we report on a major hotspot of Adélie penguin abundance identified in the Danger

Constructing a multiple‐part morphospace using a multiblock method
Methods in Ecology and Evolution, 2023 Popular current methods for quantifying variation in biological shape are well‐suited to analyses of isolated parts (e.g. the same bone from the skeletons of many individuals).
