Coastal connectivity of marine predators over the Patagonian Shelf during the highly pathogenic avian influenza outbreak

Ecography, Volume 2024, Issue 11, November 2024.
Animal movement and population connectivity are key areas of uncertainty in efforts to understand and predict the spread of infectious disease. The emergence of highly pathogenic avian influenza (HPAI) in South America poses a significant threat to globally significant populations of colonial breeding marine predators in the South Atlantic.

Unexpected Delayed Incursion of Highly Pathogenic Avian Influenza H5N1 (Clade 2.3.4.4b) Into the Antarctic Region

Influenza and Other Respiratory Viruses, Volume 18, Issue 10, October 2024.
ABSTRACT The current highly pathogenic avian influenza H5N1 panzootic is having substantial impacts on wild birds and marine mammals. Following major and widespread outbreaks in South America, an incursion to Antarctica occurred late in the austral summer of 2023/2024 and was confined to the region of the Antarctic Peninsula.

Corticosterone predicts foraging behavior and parental care in Macaroni Penguins [PDF]

, 2012
Corticosterone has received considerable attention as the principal hormonal mediator of allostasis or physiological stress in wild animals. More recently, it has also been implicated in the regulation of parental care in breeding birds, particularly ...

The ephemeral microbiota: Ecological context and environmental variability drive the body surface microbiota composition of Magellanic penguins across subantarctic breeding colonies

Molecular Ecology, Volume 33, Issue 17, September 2024.
Abstract Environmental microbes routinely colonize wildlife body surface microbiota. However, animals experience dynamic environmental shifts throughout their daily routine. Yet, the effect of ecological shifts in wildlife body surface microbiota has been poorly explored.

Continuous daily sampling of airborne eDNA detects all vertebrate species identified by camera traps

Environmental DNA, Volume 6, Issue 4, July–August 2024.
In this manuscript, we report on our study using airborne eDNA to monitor terrestrial vertebrate biodiversity in nature and compare the results with detections made using camera traps. Airborne eDNA detected all species identified using camera traps and many additional species.

Study of bacteria isolated from the foot pad of Spheniscus magellanicus with and without bumblefoot

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
The bumblefoot or pododermatitis is among the diseases with the highest morbidity in Magellanic penguins, sometimes evolving to septicemia and death. Therefore, this study aimed to relate the main species involved in the disorder, as well as the in vitro
