Colour change and colour phases in Lethrinidae with insights into ecology [PDF]

open access: yesEcology and Evolution, 2023
Colour 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.

Colour change of twig-mimicking peppered moth larvae is a continuous reaction norm that increases camouflage against avian predators [PDF]

open access: yesPeerJ, 2017
Camouflage, and in particular background-matching, is one of the most common anti-predator strategies observed in nature. Animals can improve their match to the colour/pattern of their surroundings through background selection, and/or by plastic colour ...

Testing multiple hypotheses on the colour change of treefrogs in response to various external conditions [PDF]

open access: yesScientific Reports, 2023
Amphibians are famous for their ability to change colours. And a considerable number of studies have investigated the internal and external factors that affect the expression of this phenotypic plasticity.

The extent of rapid colour change in male agamid lizards is unrelated to overall sexual dichromatism [PDF]

open access: yesEcology and Evolution, 2023
Dynamic colour change is widespread in ectothermic animals, but has primarily been studied in the context of background matching. For most species, we lack quantitative data on the extent of colour change across different contexts.

Explanation of the Colour Change in Alexandrites. [PDF]

open access: yesSci Rep, 2020
AbstractAlexandrites are remarkable and rare gemstones. They display an extraordinary colour change according to the ambient lighting, from emerald green in daylight to ruby red in incandescent light from tungsten lamps or candles. While this colour change has been correctly attributed to chromium impurities and their absorption band in the yellow ...

Dynamic colour change as a signalling tool in bluelined goatfish (Upeneicthtys lineatus) [PDF]

open access: yesEcology and Evolution, 2023
Many animal species can rapidly change their body colouration and patterning, but often the ecological drivers of such changes are unknown. Here, we explored dynamic colour change in the bluelined goatfish, Upeneichthys lineatus, a temperate marine ...

Adaptive colour change and background choice behaviour in peppered moth caterpillars is mediated by extraocular photoreception. [PDF]

open access: yesCommun Biol, 2019
Light sensing by tissues distinct from the eye occurs in diverse animal groups, enabling circadian control and phototactic behaviour. Extraocular photoreceptors may also facilitate rapid colour change in cephalopods and lizards, but little is known about

The Geographical Variation of Colour Change in the Arabian Killifish (Aphaniops dispar Sensu Lato) From Freshwater and Marine Ecosystems [PDF]

open access: yesEcology and Evolution
Widely distributed animals may exhibit substantial plastic physiological, morphological and behavioural responses to environmental changes. One such extraordinary form of plasticity is colour change, which varies substantially among most taxonomic groups.

Influence of Wine pH and Ethanol Content on the Fining Efficacy of Proteins from Winemaking By-Products

open access: yesFoods, 2022
Wine color and limpidity are important aspects of consumer preferences. The alteration of these parameters can damage wine’s appearance but also its mouthfeel characteristics due to its relationship with attributes such as bitterness and astringency ...
