Birds of many feathers? Examining perceptions among US birders following the American Ornithological Society's eponymous renaming decision

People and Nature, EarlyView.
Abstract In 2023, the American Ornithological Society announced it will phase out the English eponymous (honorific) names of 152 bird species in the United States and Canada, some of which are named after historical figures with racist, genocidal, or otherwise violent histories that serve as reminders of ornithology's exclusive origins.

Chicken feather protein hydrolysate as a low cost peptone source for microbial cultivation: A promising perspective of economic and environmental advantage

Case Studies in Chemical and Environmental Engineering
Peptones are one of the priciest culture components utilized in the cultivation of microorganisms. The objective of this work was to prepare feather hydrolysate peptone from chicken feathers using Bacillus subtilis ES5 (GenBank: OQ034477).

Ectopic Feather Follicles in a Chicken Teratoma or Malformation

Poultry Science, 1975
At necropsy of an 8-week-old pullet a 0.75 X 5.0 cm. yellowish, moderately firm cigar-shaped object was seen in the greater abdominal air sac lying parallel to the border of the right hepatic lobe. A capsule of 5 tissue layers (from inside outward-stratified squamous epithelium fibrous tissue, longitudinal muslce, fibrous tissue and circular muscle ...

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Embryotoxic Effects of Monosodium Methyl Arsenate (MSMA) on Gallus gallus: Morphological and Morphometric Evidence of Developmental Disruptions

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities and the large volume of compounds released into the environment are sources of contamination for plants, animals, and humans. The herbicide monosodium methyl arsenate (MSMA) ranks among the best‐selling agricultural pesticides in Brazil.

Mechanisms of early- and late-feathering in Qingyuan partridge chickens

Biotechnology & Biotechnological Equipment, 2019
Long non-coding RNAs (lncRNAs) are important in feather development and feathering patterns, but few studies on this subject have been conducted in chickens.

Parturition timing and the pre‐ and post‐partum behaviour of female moose assessed using animal‐borne video and movement‐based approaches

Wildlife Biology, EarlyView.
Limited information on moose calving behaviour, including parturition timing, cow‐calf interactions, and pre‐ and post‐partum movement patterns hinder our ability to define calving phenology and habitat use. GPS‐collars were deployed on 89 female moose over five years, including eight collars equipped with animal‐borne video and environmental data ...

Chicken feather dissolution to obtain keratin

Discover Chemistry
Abstract The dissolution of chicken feathers was investigated for the purpose of reducing solid waste and obtaining keratin. For the first part, the effects of sodium sulfite (0.05–0.3 M), urea (0–4 M), temperature (50–85 °C), and incubation time (2–4 h) on feather dissolution were investigated via a factorial design.
