Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Do Marine Mammals Diversify More Slowly Than Non‐Marine Mammals?

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Species richness is generally lower in marine than in terrestrial ecosystems, but the reasons behind this disparity remain unclear. This study examines whether marine mammals diversify at a slower pace than their non‐marine counterparts, aiming to shed light on the factors explaining potential diversification differences among them ...

Primer registro en Chile de Antarctophthirus microchir (Anoplura) en lobo marino común (Otaria flavescens) [PDF]

, 2008
The ectoparasitic fauna associated to marine mammals is scarcely known in Chile. This report deals with a sample of Anoplura parasites collected from adult and juvenile Otaria flavescens, the southern sea lion, at the Los Lagos Region, Chile.

First Comprehensive Study of Telomere Length Measured by Southern Blot Hybridization and Oxidative Stress Across 12 Captive Marine Mammal Species

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Telomeres, repetitive nucleotide sequences at chromosome ends, shorten with oxidative damage and cell replication, and are increasingly used as biomarkers of stress and physiological state. Despite this potential, telomere length (TL) in marine mammals has been measured using Southern blot hybridization in only a few cases, often from ...

Exploring Marine Mammal Cognition as a Conservation Tool

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.
