Earth history and the passerine superradiation [PDF]

Proceedings of the National Academy of Sciences, 2019
Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on the diversification of the hyperdiverse perching birds (passerines) is unclear because family level relationships are unresolved and the timing of splitting events among lineages is uncertain.

Testing the causal mechanism of the peninsular effect in passerine birds from South Korea.

PLoS ONE, 2021
The peninsular effect is a geographical phenomenon that explains patterns of species richness. Given that spatial variation in species richness along a peninsular may be driven by multiple processes, we aimed to identify the sources of latitudinal ...

On the use of body mass measures in severity assessment in laboratory passerine birds [PDF]

, 2022
\ua9 2022 Universities Federation for Animal Welfare. Criteria for assessing the severity of scientific procedures in laboratory rodents include the loss of body mass. However, guidance is limited for passerine birds and application of criteria developed

DNA metabarcoding Passerine bird feces at tree-line uncovers little intra- and inter-species dietary overlap [PDF]

, 2023
High-elevation insectivorous birds are currently confronted with the reality of a changing climate, land use shifts, and the decline of many prey groups. The diet dynamics among many imperiled animals in this group are still unresolved.

Migratory status is not related to the susceptibility to HPAIV H5N1 in an insectivorous passerine species [PDF]

, 2009
Migratory birds have evolved elaborate physiological adaptations to travelling, the implications for their susceptibility to avian influenza are however unknown.

Avian energetics: The passerine/non-passerine dichotomy

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2016
Whether passerines collectively have a higher mean mass-independent basal rate of metabolism than the mean of other birds has been controversial. The conclusion that no difference exists was based on phylogenetic analyses. Higher basal rates, however, have been repeatedly seen in passerines and demonstrated by ANCOVA analyses. Several studies indicated

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 ...

The link between colorfulness and extinction risk across the world's passerine birds. [PDF]

Conserv Biol
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Comparative anatomy of the passerine carpometacarpus helps illuminate the early fossil record of crown Passeriformes. [PDF]

, 2022
The hyper-diverse clade Passeriformes (crown group passerines) comprises over half of extant bird diversity, yet disproportionately few studies have targeted passerine comparative anatomy on a broad phylogenetic scale.

Infection by a helminth parasite is associated with changes in DNA methylation in the house sparrow

Ecology and Evolution, 2022
Parasites can exert strong selective pressures on their hosts and influence the evolution of host immunity. While several studies have examined the genetic basis for parasite resistance, the role of epigenetics in the immune response to parasites is less
