Dynamic colour change and the confusion effect against predation. [PDF]
Sci Rep, 2019 The confusion effect - the decreased attack-to-kill ratio of a predator with increase in prey group size - is thought to be one of the main reasons for the evolution of group living in animals.

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

Photonic crystals cause active colour change in chameleons. [PDF]
Nat Commun, 2015 Many chameleons, and panther chameleons in particular, have the remarkable ability to exhibit complex and rapid colour changes during social interactions such as male contests or courtship.

In vitro study of effects of aging and processing conditions on colour change in maxillofacial silicone elastomers. [PDF]
BMC Oral Health, 2019 The inherent colour change in maxillofacial silicone elastomers becomes perceptible 6–12 months after fabrication. Determining the factors that accelerate the degradation of the prosthesis can help the clinicians increase its life span.

Camouflage through colour change: mechanisms, adaptive value and ecological significance. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2017 Animals from a wide range of taxonomic groups are capable of colour change, of which camouflage is one of the main functions. A considerable amount of past work on this subject has investigated species capable of extremely rapid colour change (in seconds)

The adaptive value of camouflage and colour change in a polymorphic prawn. [PDF]
Sci Rep, 2018 Camouflage has been a textbook example of natural selection and adaptation since the time of the earliest evolutionists. However, aside from correlational evidence and studies using artificial dummy prey, experiments directly showing that better ...

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

Liquid-induced colour change in a beetle: the concept of a photonic cell. [PDF]
Sci Rep, 2016 The structural colour of male Hoplia coerulea beetles is notable for changing from blue to green upon contact with water. In fact, reversible changes in both colour and fluorescence are induced in this beetle by various liquids, although the mechanism ...

Optimisation of ANN topology for predicting the rehydrated apple cubes colour change using RSM and GA. [PDF]
Neural Comput Appl, 2018 In this study, an efficient optimisation method by combining response surface methodology (RSM) and genetic algorithm (GA) is introduced to find the optimal topology of artificial neural networks (ANNs) for predicting colour changes in rehydrated apple ...

Pollinator responses to floral colour change, nectar, and scent promote reproductive fitness in Quisqualis indica (Combretaceae). [PDF]
Sci Rep, 2016 Floral colour change is visual signals for pollinators to avoid old flowers and increase pollination efficiency. Quisqualis indica flowers change colour from white to pink to red may be associated with a shift from moth to butterfly pollination.
