Frontiers in Ecology and Evolution, 2020 The stem lineage relationships and early phenotypic evolution of Charadriiformes (shorebirds) and Gruiformes (rails, cranes, and allies) remain unresolved. It is still debated whether these clades are sister-taxa.

The molecular evolution of feathers with direct evidence from fossils
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance During the dinosaur–bird transition, feathers of bird ancestors must have been molecularly modified to become biomechanically suitable for flight. We report molecular moieties in fossil feathers that shed light on that transition. Pennaceous

The role of volatiles in aggregation and host-seeking of the haematophagous poultry red mite Dermanyssus gallinae (Acari: Dermanyssidae) [PDF]
, 2010 Infestations with ectoparasitic poultry red mites (Dermanyssus gallinae) pose an increasing threat to poultry health and welfare. Because of resistance to acaricides and higher scrutiny of poultry products, alternative and environmentally safe management

Effect of Repeated Gathering and Age on the Quality of Zatorska Goose Feathers
The Journal of Poultry Science, 2018 We investigated a reproductive flock of Zatorska geese. The birds were divided into four groups: three-year-old ganders (n=10), and one-, two-, and three-year-old layers (n=30).

A forensic approach to understanding habitat use from stable isotope analysis of (avian) claw material [PDF]
, 2003 1. The potential of using stable isotope signatures of avian claws in order to infer diet and habitat use was investigated. 2. Highly significant relationships observed between stable carbon and nitrogen isotope ratios (13C, 15N) in the claws and ...

Alternative Methods of Preparation of Soluble Keratin from Chicken Feathers
, 2017 Huge amount of keratinous waste, especially birds’ feathers, demands more value-added application instead of dumping. The present work reports the results of experiments aimed at preparing soluble keratin useful for novel bioproduct formation. The effect

Fossilized skin reveals coevolution with feathers and metabolism in feathered dinosaurs and early birds [PDF]
, 2018 Feathers are remarkable evolutionary innovations that are associated with complex adaptations of the skin in modern birds. Fossilised feathers in non-avian dinosaurs and basal birds provide insights into feather evolution, but how associated ...
