Emergence, spread, and impact of high-pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica. [PDF]

Conserv Biol
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,

Advances and Environmental Conditions of Spring Migration Phenology of American White Pelicans [PDF]

Scientific Reports, 2017
AbstractSpring migration phenology of birds has advanced under warming climate. Migration timing of short-distance migrants is believed to be responsive to environmental changes primarily under exogenous control. However, understanding the ecological causes of the advancement in avian spring migration phenology is still a challenge due to the lack of ...

The Biogeography of Great Salt Lake Halophilic Archaea: Testing the Hypothesis of Avian Mechanical Carriers

Diversity, 2018
Halophilic archaea inhabit hypersaline ecosystems globally, and genetically similar strains have been found in locales that are geographically isolated from one another.

Abundance, population trends, and negative associations with lake water levels for six colonial waterbird species over five decades in southern Manitoba

Avian Conservation and Ecology, 2021
Management of colonial waterbirds at regional, national, and continental scales requires up-to-date monitoring information on breeding locations, population sizes, and trends.

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

Biological Reviews, EarlyView.
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

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Bayesian integrated species distribution models for hierarchical resource selection by a soaring bird

Ecological Informatics
Migratory birds exhibit seasonal geographic range (hereafter, range) dynamics during the annual cycle. Few studies have examined how migratory birds select their habitats for range occupancy at the species level and space use at the individual level ...

Predicted genetic consequences of alternative population control strategies for North American plains bison in Yellowstone National Park

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Management of bison in Yellowstone National Park under the available strategies that maintained ≥3,500 individuals (1:1 sex ratio), removed <40% of the population at a time and prioritized relatives for removal were predicted to maintain genetic variation at levels consistent with long‐term conservation (>95% of existing variation).

Genomic Structure and Demographic History of the Brown Fur Seal: From the Ice Age to Current Isolation

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Arctocephalus pusillus (the brown fur seal) has historically experienced population fluctuations associated with glacial cycles and anthropogenic exploitation. Previous mitochondrial DNA (mtDNA) and microsatellite analyses suggested a post‐glacial population expansion in A.
