CHANGES IN THE COLOUR OF BUTTERFLIES [PDF]

The Canadian Entomologist, 1902
While studying the specializations of the wing in the Papilionides, the general results of which are published in the Proc. Am. Philosophical Society, Jan., 1899, I found that Iphiclides, Ajax, Marcellus, etc., differed so strongly from the type of Turnus as to be generically separable. Ajax is, in fact, allied to species having a greenish or yellowish

Microscopic theory of colour in lutetium hydride

Nature Communications, 2023
Nitrogen-doped lutetium hydride has recently been proposed as a near-ambient-conditions superconductor. Interestingly, the sample transforms from blue to pink to red as a function of pressure, but only the pink phase is claimed to be superconducting ...

Wood discoloration patterns depending on the light source

Heritage Science, 2022
The wood photodegradation, including discolouration caused by exposure to UV and solar radiation, has been intensively studied, while the effect of artificial lighting on wood has been little investigated.

Dragonflies that Change Colour: Nature's Hidden Redox Chemistry

CHIMIA, 2022
The colour distinction between male and female, and between young and mature male dragonflies of the genera Crocothemis and Sympetrum arises from simple redox chemistry.

Hydroxymethylfurfural content and colour parameters of cookies with defatted wheat germ

Czech Journal of Food Sciences, 2019
Defatted wheat germ was used to substitute wheat flour by 5-15% to produce cookies enriched with protein, fat, sugar and minerals. The effects of different level of substitution of wheat flour by defatted wheat germ and dough moisture content (20-24%) on

Colour change and colour phases in Lethrinidae with insights into ecology

Ecology and Evolution, 2023
AbstractColour change is used by a wide range of animals. It is used for intra‐ and interspecific communication and crypsis, and can occur on morphological and physiological levels. Bony fish employ rapid physiological colour change and display various types of patterns and colouration (colour phases) useful for aposematic and cryptic purposes.

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...

Advance in mechanism of plant leaf colour mutation

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2021
As a common mutation trait in plants, leaf colour mutation is related to the degree of chlorophyll and anthocyanin changes and the destruction of chloroplast structure. This study summarizes the latest research progress in leaf colour mutation mechanism,

Lizard colour plasticity tracks background seasonal changes

Biology Open, 2020
Environmental heterogeneity on a spatial and temporal scale fosters an organism's capacity to plastically alter coloration. Predation risk might favour the evolution of phenotypic plasticity in colour patterns, as individuals who change colour throughout
