Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

The Anatomical Record, Volume 309, Issue 10, Page 2725-2738, October 2026.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, Volume 101, Issue 5, Page 2190-2213, October 2026.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Opportunistic Feeding and Parasite Assemblages in Sei Whales (Balaenoptera borealis) From Southern Chile Revealed by DNA Metabarcoding

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

CNR Ozone Sounding Merged (COSM) Dataset From Existing Global Archives

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
The COSM dataset unifies over 101,000 ozonesonde profiles from SHADOZ, NDACC and WOUDC into a harmonized, quality‐controlled archive spanning 1978–2024. It improves global spatial and temporal coverage, supports climate and chemistry studies, and provides a robust resource for satellite validation, model evaluation and trend analysis.

Estuary Water Elevation Research (EWER) Dataset: Observational Data for Studying and Quantifying Water Level‐Related Hazards in Australia's Tidal Environments

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
A new dataset for studying tides and compound flood hazards in Australian estuaries. The dataset brings together disparate national and state agency records to improve coverage of estuarine systems, including upstream tidal rivers that are often excluded from ocean‐focused datasets.
