Wrinkle nanostructures generate a novel form of blue structural color in great argus flight feathers

open access: yesiScience, 2023
Summary: Currently known structural colors in feathers are caused by light scattering from periodic or amorphous arrangements of keratin, melanin, and air within barbs and barbules that comprise the feather vane. Structural coloration in the largest part

Colour change and assortment in the western rainbowfish [PDF]

open access: yes, 2010
Grouping behaviour is widespread across the animal kingdom, and is known to reduce an individual's risk of predation, for example through predator confusion.

The roles of inter- and intra-sexual selection in behavioral isolation between native and invasive pupfishes [PDF]

open access: yes, 2017
Male-male competition and female mate choice may both play important roles in driving and maintaining reproductive isolation between species. When previously allopatric species come into secondary contact with each other due to introductions, they ...

Effect of Blue Light-Emitting Diode (LED) Irradiation on Chlorophyll Metabolism in Ethylene-Degreened Early-Season Satsuma Mandarin Fruit [PDF]

open access: yesShipin Kexue, 2023
Early-season Satsuma mandarin fruit produced in Chongqing are usually harvested when the flesh reaches the acceptable internal maturity standards, while the peel is still green. In order to solve this problem, ethylene degreening treatment is widely used

Variação intraespecífica da cor da pelagem de uma espécie de pequeno roedor sul-americano [PDF]

open access: yes, 2016
Intra-specific color variation is often underestimated by researchers, and among mammalian species, intra-specific differences in coloration are poorly documented for most species.

The Unique Origin of Colors of Armchair Carbon Nanotubes

open access: yes, 2011
The colors of suspended metallic colloidal particles are determined by their size-dependent plasma resonance, while those of semiconducting colloidal particles are determined by their size-dependent band gap.

Anisotropic Effects of Oxygen Vacancies on Electrochromic Properties and Conductivity of $\gamma$-Monoclinic WO$_3$ [PDF]

open access: yes, 2016
Tungsten trioxide (WO$_3$) is a paradigmatic electrochromic material, whose peculiar optical properties in the presence of oxygen vacancies or intercalated alkali atoms have been observed and investigated for a long time.

On dispersion curve coloring for mechanical metafilters

open access: yesScientific Reports, 2022
AbstractThis paper formalizes smooth curve coloring (i.e., curve identification) in the presence of curve intersections as an optimization problem, and investigates theoretically properties of its optimal solution. Moreover, it presents a novel automatic technique for solving such a problem.

A new golden frog species of the genus Diasporus (Amphibia, Eleutherodactylidae) from the Cordillera Central, western Panama [PDF]

open access: yes, 2012
We describe the frog species Diasporus citrinobapheussp. n. from the Cordillera Central of western Panama. The new species differs from all other species in its genus in coloration, disk cover and disk pad shape, skin texture, advertisement call, and ...
