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.

Effect of sex on the gut microbiota characteristics of passerine migratory birds
Frontiers in Microbiology, 2022 The gut microbiota, considered the “invisible organ” in the host animal, has been extensively studied recently. However, knowledge about the gut microbiota characteristics of passerine migratory birds during migration is limited.

Evaluation of autumn mist‐netting data for monitoring passerine populations in interior Alaska
Wildlife Society Bulletin, 2012 We evaluated the data from 2 autumn mist‐netting stations for monitoring passerine population trends and measuring the timing of migration. Migration‐monitoring stations were operated during autumn from 1993 to 2009 at 2 interior Alaska locations: in ...

Frontiers in Ecology and Evolution, 2019 Many young birds die soon after fledging, as they lack the skills to find food and avoid predation. Post-fledging parental care is assumed to assist acquisition of these vital skills. However, we still lack empirical examples examining the length of time

Reproductive success of the wood warbler Phylloscopus sibilatrix varies across Europe
Journal of Avian Biology, 2022 Differences in population trends across a species' breeding range are ultimately linked to variation in demographic rates. In small songbirds, demographic rates related to fecundity typically have strong effects on population trends.
