Whole genome resequencing reveals genomic regions related to red plumage in ducks

open access: yesPoultry Science
: Plumage color is a characteristic trait of ducks that originates as a result of natural and artificial selection. As a conspicuous phenotypic feature, it is a breed characteristic.

Genetic Analyses for the White-Tailed Character of the Chabo (Japanese Bantam)

open access: yesThe Journal of Poultry Science, 2006
In the Chabo (Japanese Bantam) breed of native Japanese chickens, there are birds that have buff-like plumage. This plumage shows yellowish brown at the trunk and white for all the tail feathers and a part of the primaries. In other words, this plumage

Microstructures amplify carotenoid plumage signals in colorful tanagers [PDF]

open access: yes, 2019
AbstractRed, orange, and yellow carotenoid-colored plumages have been considered honest signals of condition. We comprehensively quantified carotenoid signals in the social, sexually-dimorphic tanager genusRamphocelususing scanning electron microscopy (SEM), finite-difference time-domain (FDTD) optical modeling, liquid chromatography–mass spectrometry (

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Plumage variation in the Planalto Woodcreeper (Dendrocolaptes platyrostris) and the melanocortin-1 receptor gene (MC1R) [PDF]

open access: yes, 2013
The Planalto Woodcreeper (Dendrocolaptes platyrostris) presents “pale” and “dark” plumage variants, which are distributed throughout the Cerrado and Caatinga, and throughout the Atlantic Forest, respectively.

Stimuli‐Responsive 3D‐Printed Structurally Colored Materials Based on Core–Shell Particle Architectures

open access: yesMacromolecular Materials and Engineering, EarlyView.
A novel, structurally colored and pH‐responsive filament for FDM 3D‐printing is presented, which is based on tailored core–shell particles with methacrylic acid as a comonomer in the particle shell. The pH‐responsiveness of the printed objects is achieved due to particle swelling in alkaline conditions.

Repeated divergent selection on pigmentation genes in a rapid finch radiation [PDF]

open access: yes, 2017
Instances of recent and rapid speciation are suitable for associating phenotypes with their causal genotypes, especially if gene flow homogenizes areas of the genome that are not under divergent selection.

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits

open access: yesOikos, EarlyView.
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.
