Seabird and sea duck mortalities were lower during the second breeding season in eastern Canada following the introduction of Highly Pathogenic Avian Influenza A H5Nx viruses

The paper documents reduced seabird and sea duck mortalities in eastern Canada during the 2023 breeding season compared to 2022 following HPAI introduction, with more diverse species affected in 2023.

Strengths and limitations of using participatory science data to characterize a wildlife mass mortality event

This study evaluates how well iNaturalist data captures waterbird mortality patterns during a mass mortality event caused by avian influenza, finding it effective for species and location but lacking in magnitude and taxonomic accuracy.

Geographic, ecological, and temporal patterns of seabird mortality during the 2022 HPAI H5N1 outbreak on the island of Newfoundland

Wild bird mass mortalities in eastern Canada associated with the Highly Pathogenic Avian Influenza A(H5N1) virus, 2022

The paper estimates 40,966 wild bird mortalities in eastern Canada due to H5N1 avian influenza in 2022, highlighting potential population-level impacts on Northern Gannets and American Common Eiders.

Avian influenza viruses in wild birds in Canada following incursion of the highly pathogenic H5N1 virus from Eurasia in 2021/2022

This study tracks the spread of HPAIV H5N1 in Canadian wild birds after its 2021/2022 incursion, finding widespread infection across species and regions.

High pathogenicity avian influenza (H5N1) in Northern Gannets: Global spread, clinical signs, and demographic consequences

This study tracks the global spread of HPAI H5N1 in Northern Gannets, documenting high mortality rates and demographic impacts across multiple colonies.

Species Richness and Speciation Rates for all Terrestrial Animals Emerge from a Synthesis of Ecological Theories

The paper estimates global terrestrial animal species richness and speciation rates by integrating ecological theories, finding speciation rates decrease with body size and are higher for carnivores.

Modelling parameter uncertainty reveals bushmeat yield versus survival trade-offs in heavily-hunted duiker Cephalophus spp.

The paper models parameter uncertainty in duiker hunting to show trade-offs between bushmeat yield and survival, finding that quota-based harvesting creates a yield-extinction risk trade-off while proportional harvesting avoids it but is harder to implement.

The Madingley General Ecosystem Model predicts bushmeat yields, species extinction rates and ecosystem-level impacts of bushmeat harvesting

The paper uses the Madingley General Ecosystem Model to predict bushmeat yields, extinction rates, and ecosystem impacts of harvesting duiker-sized herbivores, showing results comparable to single-species models.

Modelling variation in bushmeat harvesting among seven African ecosystems using the Madingley Model: yield, survival and ecosystem impacts

This study uses the Madingley Model to simulate bushmeat harvesting across seven African ecosystems, finding that yield and ecosystem impacts vary significantly based on climate-driven differences in trophic structure.
