Disruptive coloration and binocular disparity: breaking camouflage [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2019 Many species employ camouflage to disguise their true shape and avoid detection or recognition. Disruptive coloration is a form of camouflage in which high-contrast patterns obscure internal features or break up an animal's outline. In particular, edge enhancement creates illusory, or ‘fake’ depth edges within the animal's body.

Ancient origin and maternal inheritance of blue cuckoo eggs [PDF]
, 2016 Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or 'gentes') in avian brood parasites.

A System of Joyful Colour and its Disruptions: Architectural Colour in the German Democratic Republic [PDF]
Architectural Theory Review, 2014 This essay examines the debates around colour in East German architecture from the mid-1960s to the early 1980s. It traces the gradual relinquishing of the attempt to determine principles for the colouring of socialist architecture based on an idealised conception of socialist society as inducing “joy in life” (Lebensfreude).

Costs of colour change in fish: food intake and behavioural decisions [PDF]
, 2013 Many animals, particularly reptiles, amphibians, fish and cephalopods, have the ability to change their body colour, for functions including thermoregulation, signalling and predator avoidance.

Plant Cell, Tissue and Organ Culture (PCTOC), 2023 Abstract Potato is an important part of the traditional Norwegian diet, and the crop faces several challenges with respect to pests and diseases, as well as the increasingly challenging changes in climate. Genome editing may provide tools to improve the resilience of Norwegian potato cultivars to new climate challenges.

Stripes disrupt odour attractiveness to biting horseflies: Battle between ammonia, CO2, and colour pattern for dominance in the sensory systems of host-seeking tabanids [PDF]
Physiology & Behavior, 2013 As with mosquitoes, female tabanid flies search for mammalian hosts by visual and olfactory cues, because they require a blood meal before being able to produce and lay eggs. Polarotactic tabanid flies find striped or spotted patterns with intensity and/or polarisation modulation visually less attractive than homogeneous white, brown or black targets ...

Semantic impairment disrupts perception, memory, and naming of secondary but not primary colours.
Neuropsychologia, 2015 To investigate how basic aspects of perception are shaped by acquired knowledge about the world, we assessed colour perception and cognition in patients with semantic dementia (SD), a disorder that progressively erodes conceptual knowledge. We observed a previously undocumented pattern of impairment to colour perception and cognition characterized by: (

Characterization of four polymorphic genes controlling red leaf colour in lettuce that have undergone disruptive selection since domestication [PDF]
Plant Biotechnology Journal, 2019 SummaryAnthocyanins protect plants from biotic and abiotic stressors and provide great health benefits to consumers. In this study, we cloned four genes (Red Lettuce Leaves 1 to 4: RLL1 to RLL4) that contribute to colour variations in lettuce. The RLL1 gene encodes a bHLH transcription factor, and a 5‐bp deletion in some cultivars abolishes its ...

Cognitive dimensions of predator responses to imperfect mimicry? [PDF]
, 2007 Many palatable insects, for example hoverflies, deter predators by mimicking well-defended insects such as wasps. However, for human observers, these flies often seem to be little better than caricatures of wasps – their visual appearance and ...
