Antennae on transmitters on free-living marine animals: Balancing budgets on the high wire [PDF]

open access: yes, 2004
The effect of externally mounted antennae on the energetics of penguins was studied by mounting various antennae on a transducer fixed to a model Magellanic penguin Spheniscus magellanicus to determine drag, run at speeds of up to 2 m s–1 in a swim canal.

ISOLATION AND IDENTIFICATION OF Aspergillus spp. FROM THE WATER USED FOR REHABILITATION OF MAGELLANIC PENGUINS

open access: yesCiência Animal Brasileira, 2015
Aspergillosis is the main cause of mortality in captivity penguins. The infection occurs mainly by conidia inhalation of the Aspergillus genus, however, the fungus can also be dispersed by water.

Up-beat motion in swimming limbs: New insights into assessing movement of free-living marine vertebrates. [PDF]

open access: yes, 2003
A new system is presented for assessing the movement of animal limbs including, after suitable calibration, quantification of limb stroke frequency and amplitude, which may be used to derive limb angular velocity and acceleration.

First record of feather-loss disorder in Antarctic penguins [PDF]

open access: yes, 2014
Little is known about diseases affecting Antarctic wildlife (Kerry & Riddle 2009). Understanding the patterns, causes and effects of disease in these populations is crucial as many of these species are already threatened by rapid environmental changes ...

Bayesian phylogenetic estimation of fossil ages

open access: yes, 2016
Recent advances have allowed for both morphological fossil evidence and molecular sequences to be integrated into a single combined inference of divergence dates under the rule of Bayesian probability.

Brownotate, a Comprehensive Solution to Generate Protein Sequence Databases for Any Species

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Proteomics is strengthening research in biology and the diversification of the model organisms studied is very promising for fully understanding the complexity of biological principles. However, the lack of protein sequence databases for many species is a major bottleneck.

Humboldt penguins monitored via VHF telemetry [PDF]

open access: yes, 1998
VHF telemetry was used in November and December 1995 on 8 Humboldt penguins Spheniscus humboldti breeding at Pan de Azúcar Island (26°S, 70°W), Northern Chile, to determine at-sea behaviour of the birds.

Assessing Conflict Potential Between Birds and Small‐Scale Fisheries in Lake Titicaca

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Globally, fisheries bycatch constitutes a threat to aquatic birds. However, while the threat is global, the threat from bycatch in inland fisheries, and from artisanal or small‐scale fishing, is particularly understudied. Here, we present the first attempt to map the vulnerability of birds to fisheries bycatch, and the conflict potential ...

Contemporary outbreaks of different avipoxviruses in Humboldt penguins of wild animal park Planckendael and in chickens of commercial poultry farms in Belgium [PDF]

open access: yes, 2017
In the present study, the first outbreak of a penguinpox virus (PPV) in Humboldt penguins (Spheniscus humboldd) and four outbreaks of fowlpox virus (FPV) in layer chickens are reported.
