Amphipod crustaceans in the diet of pygoscelid penguins of the King George Island, South Shetland Islands, Antarctica [PDF]
, 1981 Paper received 10 December 1980.Information is presented concerning amphipod crustaceans eaten by three penguin species breeding on King George Island: Pygoscelis adeliae, P. antarctica and P. papua.

Antarctic Record, 1972 Aerophotography was applied in an attempt to count the number of Adelie penguins at the rookery on Rumpa Island near Syowa Station, Antarctica. The author first aimed at pursuing the fluctuations in the number of Adelie penguins at the rookery during ...

Penguins and their noisy world
Anais da Academia Brasileira de Ciências, 2004 Penguins identify their mate or chick by an acoustic signal, the display call. This identification is realized in a particularly constraining environment: the noisy world of a colony of thousands of birds. To fully understand how birds solve this problem

International Journal for Parasitology: Parasites and Wildlife, 2022 Avian malaria, caused by Plasmodium spp. and transmitted by mosquitos, is a leading cause of mortality of captive penguins. Antimalarial drugs are currently used to control infections in penguins.

B meson decays to baryons in the diquark model
, 2001 We study B meson decays to two charmless baryons in the diquark model, including strong and electroweak penguins as well as the tree operators. It is shown that penguin operators can enhance $\bar{B} \to \Bb_s \bar{\Bb}$ considerably, but affect $\bar{B}

Bayesian total evidence dating reveals the recent crown radiation of penguins [PDF]
, 2016 The total-evidence approach to divergence-time dating uses molecular and morphological data from extant and fossil species to infer phylogenetic relationships, species divergence times, and macroevolutionary parameters in a single coherent framework ...

Rescattering Effects, Isospin Relations and Electroweak Penguins in B -> pi K Decays
, 1997 It is argued that, in the presence of soft final-state interactions, the diagrammatic amplitude approach adopted in many analyses of hadronic B decays into light mesons can be misleading when used to deduce the unimportance of certain decay topologies ...

Mixing-Induced CP Violation in the Decay $B_d\to K^0 \bar K^0$ within the Standard Model
, 1994 Recently, flavour $SU(3)$ symmetry of strong interactions has been combined with certain dynamical assumptions to derive triangle relations among $B$-meson decay-amplitudes.
