Wild birds are important hosts of influenza A viruses (IAVs) and play an important role in their ecology. The emergence of the A/goose/Guangdong/1/1996 H5N1 (Gs/GD) lineage marked a shift in IAV ecology, leading to recurrent outbreaks and mortality in wild birds from 2002 onwards. This lineage has evolved and diversified over time, with a recent important derivative being the 2.

Methods: Color analysis and untargeted high-resolution mass spectrometry-based metabolomic analysis were performed on eight beans of each type. Mass spectral data processing, univariate and multivariate statistical methods were conducted for classification of beans and selection of discriminant features.
Article Synopsis
- The study analyzes beluga whale carcasses from the St. Lawrence Estuary, Canada, since 1983 to understand the nutritional condition related to various causes of death.
- By refining death categories and using Bayesian linear models, researchers identified distinct nutritional conditions linked to specific causes, such as lower conditions for those that died from neonatal mortality and primary starvation.
- The findings suggest a connection between chronic health issues and poorer nutritional conditions in belugas, while surprising results show that whales dying from trauma did not necessarily exhibit the highest nutritional health.
A necropsy was performed on a Common Raven () presenting an opportunistic fungal respiratory infection and a bursal lymphoid depletion with inclusion bodies, suggestive of a circovirus infection. High-throughput sequencing of circular DNA in the bursa of Fabricius revealed a complete genome sequence of a strain.

This contributes to the One Health Approach, which investigates health issues at the intersection of people, wild and domestic animals, together with their changing environments. Nonetheless, the emerging field of wildlife cancer is currently constrained by methodological limitations in detecting cancer using non-invasive sampling.
