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 ...

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, 2014 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 ...

Edge enhancement improves disruptive camouflage by emphasising false edges and creating pictorial relief [PDF]
, 2016 Disruptive colouration is a visual camouflage composed of false edges and boundaries. Many disruptively camouflaged animals feature enhanced edges; light patches are surrounded by a lighter outline and/or a dark patches are surrounded by a darker outline.

A disruption of colour priming following continuous theta burst transcranial magnetic stimulation
Cortex, 2012 It is well established that the presentation of one visual attribute (e.g., colour, motion) can improve the likelihood of the same attribute being detected on a subsequent trial (Tulving and Schacter, 1990). There is growing evidence to suggest that this effect is driven in a bottom-upmanner (Maljkovic and Nakayama, 1994), which is dependent upon ...

Coevolution in Action: Disruptive Selection on Egg Colour in an Avian Brood Parasite and Its Host
PLoS ONE, 2010 Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection.Here, we show through detailed field studies and experimental procedures that the ashy-throated ...

Alienopterix santonicus sp. n., a metallic cockroach from the Late Cretaceous ajkaite amber (Bakony Mts, western Hungary) documents Alienopteridae within the Mesozoic Laurasia [PDF]
, 2023 Cockroaches (Blattaria s. str.) were documented from numerous amber localities around the world, representing both extinct and extant families. Alienopteridae is an extinct cockroach family known only from the Cretaceous of Gondwana (Brazil, Botswana ...

Biological Journal of the Linnean Society, 2019 AbstractMany theoretical studies have suggested that disruptive selection plays an important role in phenotypic divergence, but few studies have determined the action of disruptive selection on phenotypic divergence via field studies. This study investigated the effect of disruptive selection on shell colour polymorphism in the Japanese land snail ...
