Dieta y dinámica poblacional del león marino del sur ("Otaria flavescens") en Patagonia

, 2010
[spa] El león marino del sur (Otaria flavescens), al igual que otros pinnípedos, fue intensamente perseguido por su piel y grasa. En Patagonia se estima que en la década de 1960, cuando cesó la explotación, la población se había reducido a menos del 10% de su tamaño original y permaneció sin crecer hasta la década de 1980.

EFSA Journal, Volume 23, Issue 4, April 2025.
Abstract Between 7 December 2024 and 7 March 2025, 743 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (239) and wild (504) birds across 31 countries in Europe. HPAI A(H5N1) virus detections were predominant and mainly located in central, western and south‐eastern Europe.

Potential Spatial Mismatches Between Marine Predators and Their Prey in the Southern Hemisphere in Response to Climate Change

Global Change Biology, Volume 31, Issue 2, February 2025.
Global change is reshaping marine habitats, altering predator–prey interactions and food web dynamics. Using Boosted Regression Trees, we assess habitat suitability shifts for crustaceans, fish, penguins, and pinnipeds across three Southern Hemisphere regions from 1850 to 2100 under two climate scenarios.

Organochlorine Residues in South American Sea Lions, Otaria flavescens (Shaw, 1800): Bioaccumulation and Time Trends

Bulletin of Environmental Contamination and Toxicology, 2010
Blubber from stranded South American sea lions (Otaria flavescens) was sampled between 1991 and 2005 on the Peninsula Valdés in Argentina and analyzed for organochlorine (OC) pollutants. Mean blubber concentrations, expressed on an extractable basis, were 686 (SD = 1,060) ng g(-1) for dichlorodiphenyl trichloroethane (tDDT) and 735 (SD = 787) ng g(-1 ...
