Blood transcriptome resources of chinstrap () and gentoo () penguins from the South Shetland Islands, Antarctica [PDF]

open access: yesGenomics & Informatics, 2019
The chinstrap (Pygoscelis antarcticus) and gentoo (P. papua) penguins are distributed throughout Antarctica and the sub-Antarctic islands. In this study, high-quality de novo assemblies of blood transcriptomes from these penguins were generated using the

The Impacts of a Commercial Bubble Curtain on Zoo-Housed African Penguin (Spheniscus demersus) Swimming Behavior

open access: yesJournal of Zoological and Botanical Gardens, 2023
Swimming is an important behavior for all penguin species. However, zoo-housed penguins typically do not swim as often as their wild counterparts, which may have consequences for their health and welfare. In an effort to increase the swimming time of the

Vector incrimination and transmission of avian malaria at an aquarium in Japan: mismatch in parasite composition between mosquitoes and penguins

open access: yesMalaria Journal, 2021
Background Captive populations of penguins outside of their natural distributions are often maintained in outdoor facilities, such as zoos and aquariums.

Outbreak of avian malaria associated to multiple species of Plasmodium in magellanic penguins undergoing rehabilitation in southern Brazil. [PDF]

open access: yesPLoS ONE, 2014
Avian malaria is a mosquito-borne disease caused by Plasmodium spp. Avian plasmodia are recognized conservation-threatening pathogens due to their potential to cause severe epizootics when introduced to bird populations with which they did not co-evolve.

Comparison of Gut Microbiota between Gentoo and Adélie Penguins Breeding Sympatrically on Antarctic Ardley Island as Revealed by Fecal DNA Sequencing

open access: yesDiversity, 2021
There are two pygoscelid penguins, the Gentoo (Pygoscelis papua Forster, 1781) and Adélie (P. adeliae Hombron and Jacquinot, 1841) penguins, breeding sympatrically on Ardley Island, Fildes Peninsula region, South Shetlands, Antarctica.

Epidemiology and molecular phylogeny of Babesia sp. in Little Penguins Eudyptula minor in Australia

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2015
Blood parasites are potential threats to the health of penguins and to their conservation and management. Little penguins Eudyptula minor are native to Australia and New Zealand, and are susceptible to piroplasmids (Babesia), hemosporidians (Haemoproteus,

Penguins are competent hosts of Haemoproteus parasites: the first detection of gametocytes, with molecular characterization of Haemoproteus larae

open access: yesParasites & Vectors, 2020
Background The majority of penguins (Sphenisciformes) have evolved in areas with weak or absent transmission of haemosporidian parasites and are usually naïve to avian haemosporidian infections.

Responses of king penguin Aptenodytes patagonicus adults and chicks to two food-related odours [PDF]

open access: yes, 2016
Increasing evidence suggests that penguins are sensitive to dimethyl sulphide (DMS), a scented airborne compound that a variety of marine animals use to find productive areas of the ocean where prey is likely to be found.

The topical segregation of penguins of genus Pygoscelis and antarctic shags (Phalarocorax bransfieldensis)

open access: yesУкраїнський антарктичний журнал, 2017
The penguin fauna succession is studied from the western part of Graham Land. Due to climatic changes (warming up) the distribution of Gentoo penguins is observed and decreasing of area for Adelie penguins is indicated too.

Fat penguins and imaginary penguins in perturbative QCD [PDF]

open access: yes, 2000
We evaluate $B\to K\pi$ decay amplitudes in perturbative QCD picture. It is found that penguin contributions are dynamically enhanced by nearly 50% compared to those assumed in the factorization approximation.
