Highly Pathogenic Avian Influenza Viruses and Generation of Novel Reassortants, United States, 2014–2015

Emerging Infectious Diseases, 2016
Asian highly pathogenic avian influenza A(H5N8) viruses spread into North America in 2014 during autumn bird migration. Complete genome sequencing and phylogenetic analysis of 32 H5 viruses identified novel H5N1, H5N2, and H5N8 viruses that emerged in ...

One Health approach uncovers emergence and dynamics of Usutu and West Nile viruses in the Netherlands

Nature Communications
Mosquito-borne arboviruses, including Usutu virus (USUV) and West Nile virus (WNV), are emerging threats in Europe, with changes in climate, land use shifts, and increasing global connectivity influencing their dynamics.

Combining Individual‐Based Radio‐Tracking With Whole‐Genome Sequencing Data Reveals Candidate for Genetic Basis of Partial Migration in a Songbird

Ecology and Evolution
Partial migration is a phenomenon where migratory and resident individuals of the same species co‐exist within a population, and has been linked to both intrinsic (e.g., genetic) as well as environmental factors.

Does Age, Residency, or Feeding Guild Coupled with a Drought Index Predict Avian Health during Fall Migration?

Animals, 2022
Birds are good indicators of environmental change and are often studied for responses to climate. Many studies focus on breeding birds, while fewer look at the migration period, which is a critical time for many birds.

The Role of Migration in Maintaining the Transmission of Avian Influenza in Waterfowl: A Multisite Multispecies Transmission Model along East Asian-Australian Flyway

Canadian Journal of Infectious Diseases and Medical Microbiology, 2018
Background. Migratory waterfowl annually migrate over the continents along the routes known as flyways, serving as carriers of avian influenza virus across distant locations.

Comparative osteohistology of Hesperornis with reference to pygoscelid penguins: the effects of climate and behaviour on avian bone microstructure [PDF]

Royal Society Open Science, 2014
The broad biogeographic distribution of Hesperornis fossils in Late Cretaceous Western Interior Seaway deposits has prompted questions about whether they endured polar winters or migrated between mid- and high latitudes.

Effects of blood parasite infections on spatiotemporal migration patterns and activity budgets in a long‐distance migratory passerine

Ecology and Evolution, 2021
How blood parasite infections influence the migration of hosts remains a lively debated issue as past studies found negative, positive, or no response to infections.

Conservation of North American migratory birds: insights from developments in tracking technologies

Avian Conservation and Ecology
Conservation of North American migratory birds requires information about their movements and regulating factors throughout the annual cycle. Over the past 10 or more years, improvements in tracking technology and quantitative approaches to assessing ...

Patterns of neurogenesis and amplitude of Reelin expression are essential for making a mammalian-type cortex.

PLoS ONE, 2008
The mammalian neocortex is characterized as a six-layered laminar structure, in which distinct types of pyramidal neurons are distributed coordinately during embryogenesis.

Characterizing the microbiome of ectoparasitic louse flies feeding on migratory raptors.

PLoS ONE, 2020
Louse flies (Diptera: Hippoboscidae) are obligate ectoparasites that often cause behavioral, pathogenic, and evolutionary effects on their hosts. Interactions between ectoparasites and avian hosts, especially migrating taxa, may influence avian pathogen ...
