Beach Attendance in Magellanic PenguinsSpheniscus magellanicus

Ardeola, 2013
Seabirds depend on a variety of terrestrial habitats during the part of their life cycle that they spend on land. Understanding the temporal patterns of use of these habitats provides insights into their ecological requirements, and ultimately helps to direct efforts that ensure the birds' protection.

Rhinonyssus sphenisci (Acari: Rhinonyssidae) in Magellanic Penguin (Spheniscus magellanicus)

Polar Biology, 2017
Nasal mites occur in different groups of birds, but little is known about their diversity associated with seabirds. The aim of this study was to verify the presence of nasal mites in the Magellanic Penguin (Spheniscus magellanicus), and to study their parasitological indices.

Factors Affecting Brood Patch Development in Magellanic PenguinsSpheniscus magellanicus

Acta Ornithologica, 2016
Abstract. Brood patches allow the transfer of heat to eggs for their successful embryonic development, and in many species determine egg temperature during incubation. We investigated brood patch development of Magellanic Penguins Spheniscus magellanicus in Isla Quiroga, Argentina, during 2012–2013.

Semen collection, characterization, and cryopreservation in a Magellanic penguin (Spheniscus magellanicus)

Zoo Biology, 1999
A cooperative method was developed for collecting semen from a Magellanic penguin. Ejaculate parameters and semen production during a breeding season were characterized. Experiments were performed to study the effect on penguin spermatozoa of two temperatures (4°C and 21°C) for short-term storage, and two cryoprotectants (dimethylsulfoxide [DMSO] and ...

CORNEAL ENDOTHELIUM OF THE MAGELLANIC PENGUIN (SPHENISCUS MAGELLANICUS) BY SCANNING ELECTRON MICROSCOPY

Journal of Zoo and Wildlife Medicine, 2005
The corneal endothelium is essential for the maintenance of the corneal transparency. The aim of this study was to examine the morphology of the endothelial surface and perform morphometric analysis of the normal corneal endothelial cells of the Magellanic penguin (Spheniscus magellanicus) using scanning electron microscopy.

Persistent organic pollutants in juvenile Magellanic Penguins (Spheniscus magellanicus) in South America

Chemosphere, 2016
Magellanic penguins, Spheniscus magellanicus, are the most abundant penguins living in temperate regions of South America and are good indicators of environmental pollution in the region. Persistent organic pollutants (POPs) were detected in the liver of Magellanic penguins found debilitated or dead on the beaches of Brazil (states of Rio de Janeiro ...
