Environmentally induced changes in carotenoid-based coloration of female lizards: a comment on Vercken et al. [PDF]
, 2008 Colouration may either reflect a discrete polymorphism potentially related to life-history strategies, a continuous signal related to individual quality or a combination of both. Recently, Vercken et al. [J. Evol. Biol.

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 ...

A trade-off between overheating and camouflage on shorebird eggshell colouration [PDF]
, 2016 In ground-nesting birds egg colour and appearance may have evolved due to opposite selection pressures. Pigmentation and spottiness make the eggs darker and have been suggested to improve camouflage.

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: (

Establishing the behavioural limits for countershaded camouflage [PDF]
, 2017 Countershading is a ubiquitous patterning of animals whereby the side that typically faces the highest illumination is darker. When tuned to specific lighting conditions and body orientation with respect to the light field, countershading minimizes the ...

Application of a novel method for soil aggregate stability measurement by laser granulometry with sonication [PDF]
, 2013 Aggregate stability is an important physical indicator of soil quality, and so methods are required to measure it rapidly and cost-effectively so that sufficient data can be collected to detect change with adequate statistical power. The standard methods

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 ...

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.

There is more to the picture than meets the eye: adaptation for crypsis blurs phylogeographical structure in a lizard [PDF]
, 2016 Aim: We examined dorsal coloration in and genetic relationships among Iberian populations of the lizard Psammodromus algirus to determine the extent to which the current distribution of phenotypic variation is correlated with phylogeographical history or

Interspecific visual signalling in animals and plants: a functional classification [PDF]
, 2017 Organisms frequently gain advantages when they engage in signalling with individuals of other species. Here we provide a functionally structured framework of the great variety of interspecific visual signals seen in nature, then describe the different ...
