Supermatrix Phylogenetic Tree of Passerine Birds From the Indo‐Australian Archipelago Highlights Contrasting Histories of Regional Endemism [PDF]
Ecology and EvolutionThe Indo‐Australian Archipelago (IAA) is a biodiversity hotspot characterized by high levels of biotic endemism and turnover. Explanations for these biodiversity patterns tend to focus on the role of the complex and dynamic geological history of the ...

Description of the Seminiferous Epithelium Cycle Stages in the Zebra Finch Taeniopygia guttata [PDF]
AnimalsSpermatogenesis in passerine birds remains poorly characterized. Previous studies focused on the steps of spermiogenesis, while a detailed staging of the seminiferous epithelium cycle is still lacking for this order.

DNA barcoding of passerine birds in Iran [PDF]
ZooKeysExploring genetic diversity is essential for precise species delimitation, especially within taxonomically complex groups like passerine birds. Traditional morphological methods often fail to resolve species boundaries; however, DNA barcoding, particularly through the mitochondrial cytochrome c oxidase subunit I (COI) gene, provides a powerful ...

Salmonella and Salmonellosis in Wild Birds [PDF]
AnimalsSalmonella enterica is an important bacterial pathogen in humans and warm-blooded animals. Wild bird species represent both a potential reservoir for zoonotic infection and as a susceptible host to infection by host-adapted variants.

Nitrogen Isotopes Suggest Sex‐Based Diet Differences on the Breeding Grounds for a Sexually Monomorphic Migratory Passerine [PDF]
Ecology and EvolutionDifferential foraging by sex can have important implications for understanding the ecology of a species. This can be especially difficult to study through observations alone in sexually monomorphic species, such as the Golden‐crowned Sparrow (Zonotrichia

Islands contribute disproportionately high amounts of evolutionary diversity in passerine birds [PDF]
, 2015 Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major ...

Body size changes in passerine birds introduced to New Zealand from the UK [PDF]
, 2013 One feature of global geographic variation in avian body sizes is that they are larger on isolated islands than on continental regions. Therefore, this study aims to assess whether there have been changes in body size following successful establishment ...

Diet contributes to urban-induced alterations in gut microbiota : experimental evidence from a wild passerine [PDF]
, 2020 Urban sprawl increasingly affects the ecology of natural populations, including host-microbiota interactions, with observed differences in the gut microbiota between urban and rural hosts.

Eggshell pigment composition covaries with phylogeny but not with life history or with nesting ecology traits of British passerines [PDF]
, 2015 No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions.

The presence of air sac nematodes in passerines and near-passerines in southern Germany
International Journal for Parasitology: Parasites and Wildlife, 2023 Major climatic changes in conjunction with animal movement may be associated with the spread of parasites and their vectors into new populations, with potentially important consequences for population persistence. Parasites can evolve to adapt to unsuitable ecological conditions and take up refuge within new host species, with consequences for the ...
