Marine Bird Bycatch in Alaska Salmon Gillnet Fisheries

Fisheries Management and Ecology, Volume 32, Issue 5, Page 366-387, October 2025.
ABSTRACT Incidental catch in gillnet fisheries has a substantial conservation impact on marine diving birds. We synthesized available marine bird bycatch data from Alaska salmon gillnet fisheries to estimate standardized bycatch rates, model factors influencing bycatch rates, and estimate total bycatch.

Avian influenza overview June–September 2025

EFSA Journal, Volume 23, Issue 10, October 2025.
Abstract Between 7 June and 5 September 2025, 183 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (27) and wild (156) birds across 15 countries in Europe. Although HPAI A(H5N1) virus detections were predominant in western and southwestern Europe, they also occurred on the northernmost coast of Norway. More than

Phylogeography and genetic structure of two Patagonian shag species (Aves: Phalacrocoracidae)

Molecular Phylogenetics and Evolution, 2014
We compared the phylogeographic and genetic structure of two sympatric shag species, Phalacrocorax magellanicus (rock shag) and Phalacrocorax atriceps (imperial shag), from Patagonia (southern South America). We used multilocus genotypes of nuclear DNA (microsatellite loci) from 324 individuals and mitochondrial DNA sequences (ATPase) from 177 ...

Overwintering and Resident Birds in Qatar: Explorations With DNA Barcoding

Ecology and Evolution, Volume 15, Issue 7, July 2025.
We obtained DNA barcodes for 115 birds (34 species, 12 orders) in Qatar, a country with no previous barcode sequence data for wild birds. We provide insights on locally breeding species and overwintering migrants. ABSTRACT Genetic research is unevenly distributed across the globe, with most research done in temperate zones.

Tracing Waterbirds in Water: A Pilot Study on the Utility of eDNA Monitoring for Inland Australian Waterbirds

Austral Ecology, Volume 50, Issue 7, July 2025.
ABSTRACT Australia's vast network of inland wetlands attracts thousands of waterbirds to congregate and breed during ‘boom’ periods of rainfall and productivity. Monitoring waterbird biodiversity predominantly relies on annual aerial and ground‐based surveys, which may miss rare or elusive species of conservation importance.
