Pigmentation plasticity enhances crypsis in larval newts: Associated metabolic cost and background choice behaviour [PDF]
, 2017 In heterogeneous environments, the capacity for colour change can be a valuable adaptation enhancing crypsis against predators. Alternatively, organisms might achieve concealment by evolving preferences for backgrounds that match their visual traits ...

Eggshell pigment composition covaries with phylogeny but not with life history or with nesting ecology traits of British passerines [PDF]
, 2015 No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions.

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 ...

Condition-dependence, pleiotropy and the handicap principle of sexual selection in melanin-based colouration. [PDF]
, 2015 The signalling function of melanin-based colouration is debated. Sexual selection theory states that ornaments should be costly to produce, maintain, wear or display to signal quality honestly to potential mates or competitors.

A global analysis of bird plumage patterns reveals no association between habitat and camouflage [PDF]
, 2016 Evidence suggests that animal patterns (motifs) function in camouflage. Irregular mottled patterns can facilitate concealment when stationary in cluttered habitats, whereas regular patterns typically prevent capture during movement in open habitats. Bird

Is countershading camouflage robust to lighting change due to weather? [PDF]
, 2018 Countershading is a pattern of coloration thought to have evolved in order to implement camouflage. By adopting a pattern of coloration that makes the surface facing towards the sun darker and the surface facing away from the sun lighter, the overall ...

Optimizing countershading camouflage [PDF]
, 2016 Countershading, the widespread tendency of animals to be darker on the side that receives strongest illumination, has classically been explained as an adaptation for camouflage: obliterating cues to 3D shape and enhancing background matching.
