Genomic organization and molecular phylogenies of the beta (β) keratin multigene family in the chicken (Gallus gallus) and zebra finch (Taeniopygia guttata): implications for feather evolution

BMC Evolutionary Biology, 2010
Background The epidermal appendages of reptiles and birds are constructed of beta (β) keratins. The molecular phylogeny of these keratins is important to understanding the evolutionary origin of these appendages, especially feathers.

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

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 ...

Experimental and field evidence indicate that islet‐nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

Oikos, EarlyView.
Landscape features can shape the occurrence and strength of predator–prey interactions by influencing predation risk and prey distribution. In the High Arctic, some bird species select nesting sites with physical features that impede access for their main terrestrial predator, the Arctic fox.

The magnitude and economic replacement value of wild meat obtained from ‘recreational’ big game hunting in the United States

People and Nature, EarlyView.
Abstract Meat production has notable benefits for food security, nutrition and various production economies, but has elicited substantial negative environmental impacts. Recreational hunting provides an alternative to agricultural meat production for over 24 million hunters worldwide.

Enhancing spinach growth with a biofertilizer derived from chicken feathers using a keratinolytic bacterial consortium

BMC Microbiology
This study was conducted to develop a cost-effective and environmentally friendly biofertilizer by utilizing chicken feather waste. Two bacterial strains were employed to biotransform the abundant keratin protein in feathers.

Feast or famine: How food deserts, wealth and greenspace correlate with coyote diets in Seattle, Washington

People and Nature, EarlyView.
Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,
