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

Geological 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 ...

EVALUATION OF PRODUCTIVE PERFORMANCE IN TWO PLUMAGE-COLOR TYPES OF JAPANESE QUAIL USING MICROSATELLITE MARKERS. [PDF]

Egyptian Poultry Science, 2019
Two plumage-color types of Japanese quail were used to compare the meat production potentialities using five selective microsatellite markers. A total number of birds was 189 for the two plumage-colors of quail [(Brown 114; 49 males, and 65 females), and

A spatiotemporal single‐cell atlas of porcine development reveals regulatory dynamics and cellular targets of domestication

iMeta, EarlyView.
This study presents a cross‐tissue, single‐cell/single‐nucleus transcriptomic atlas spanning from prenatal to postnatal developmental stages in pig, characterizing 83 distinct cell types from 252,033 cells. Through the construction of cross‐tissue transcriptional regulatory networks and pseudotime trajectories, we revealed that organogenesis is driven ...

Evolution and Phylogenetics of the Javan Hawk‐Eagle Nisaetus bartelsi (Stresemann, 1924) Using Mitochondrial Data 爪哇鹰雕 Nisaetus bartelsi (Stresemann, 1924) 基于线粒体数据的演化与系统发育研究

Integrative Conservation, EarlyView.
This study reconstructs the phylogeny of the Javan Hawk‐Eagle (Nisaetus bartelsi) within the subfamily Aquilinae using Maximum Likelihood and Bayesian Inference algorithms on a blood sample and GenBank data. The analysis reveals that the sampled genus Nisaetus forms a monophyletic group. Furthermore, N. bartelsi occupies a sister‐taxon of N.

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

Poultry 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.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

InfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

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

The 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

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

Oikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Shank Color and Barred Plumage in Columbian-Colored Chickens

Poultry Science, 1955
Abstract MANY females produced from crosses of barred columbian, (B S e), males and red, e, females develop a greenish shank coloration by the broiler age of 8 to 12 weeks after hatching. This greenish shank coloration, often designated as “willow,” may vary in incidence from 12 to 80% of the females at the broiler age.
