Author: Published: 2025 HPAI has now affected over 300 avian species globally, including seabirds, raptors, and waterfowl, with significant mortality observed across both hemispheres. 12.06.25 Papers View on journal website The genomic signature of demographic decline in a long-distance migrant in a range-extreme population Author: Published: 2025 With increasing sophistication, genetic techniques and analyses are allowing us to delve deep into the past to show how prior environmental or demographic change has influenced species’ present day populations. This is particularly useful for scarce species that are difficult to observe and occupy remote habitats. In many species, large scale reduction in habitat availability has impacted their breeding distribution, which has been exacerbated by habitat fragmentation. Once widespread species become localised and the remaining breeding birds become increasingly isolated, this can result in reduced genetic diversity. This is the case for the Nightjar, a little-studied species, which has specialised habitat requirements and is located at the western edge of the European range. 05.06.25 Papers View on journal website Evaluating the use of carcass and testing data to assess the high pathogenicity avian influenza (HPAI) related mortality in wild birds in the United Kingdom and Crown Dependencies between 2021–2023 Author: Published: 2025 21.05.25 Papers View on journal website Assessing the vulnerability of wild bird populations to high pathogenicity avian influenza Author: Published: 2025 A vulnerability assessment to high pathogenicity avian influenza predicted mortality at the avian family, but not the species, level.
