FIRST EVIDENCE OF COLOR PATTERNS ON CONCHS OF THE LOWER MOSCOVIAN (MIDDLE PENNSYLVANIAN) COILED NAUTILOIDS FROM THE DONETS BASIN, UKRAINE

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2023
New finds of well-preserved remains of coiled nautiloids from lower Moscovian sediments (Kamenskaya Formation) of the Donets Basin (eastern Ukraine) allowed to describe the color pattern on the conch surface of species of the genera Parametacoceras ...

The giant panda is cryptic

open access: yesScientific Reports, 2021
The giant panda (Ailuropoda melanoleuca) is an iconic mammal, but the function of its black-and-white coloration is mysterious. Using photographs of giant pandas taken in the wild and state-of-the-art image analysis, we confirm the counterintuitive ...

Structural and colored disruption as camouflage strategies in two sympatric Asian box turtle species (Cuora spp.)

open access: yesGlobal Ecology and Conservation, 2020
Disruptive coloration is a common camouflage strategy that breaks body outlines and ostensibly blends organisms into complex backgrounds. However, contrasting false edges caused by an animal's structure can also break body outlines, although there is no ...

What's in a band? The function of the color and banding pattern of the Banded Swallowtail

open access: yesEcology and Evolution, 2020
Butterflies have evolved a diversity of color patterns, but the ecological functions for most of these patterns are still poorly understood. The Banded Swallowtail butterfly, Papilio demolion demolion, is a mostly black butterfly with a greenish‐blue ...

New Jurassic tettigarctid cicadas from China with a novel example of disruptive coloration [PDF]

open access: yesActa Palaeontologica Polonica, 2016
Tettigarctidae is the most primitive family of Cicadoidea, with only two relict species. Although they are relatively well known from Eurasia, Australia, Africa, and South America, their Mesozoic examples are typically preserved only as isolated ...

Disruptive and cryptic coloration [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2006
Camouflage may be achieved in three ways: crypsis, disruptive coloration and masquerade ([Endler 1981][1]). Cryptic prey resemble random samples of the visual background ([Endler 1978][2], [1981][1], [1984][3]), minimizing their signal/noise ratio (S/N).

Dissociating the effect of disruptive colouration on localisation and identification of camouflaged targets [PDF]

open access: yes, 2018
Disruptive camouflage features contrasting areas of pigmentation across the animals’ surface that form false edges which disguise the shape of the body and impede detection.

Disruptive selection and the evolution of discrete color morphs in <i>Timema</i> stick insects. [PDF]

open access: yesSci Adv, 2023
A major unresolved issue in biology is why phenotypic and genetic variation is sometimes continuous, yet other times packaged into discrete units of diversity, such as morphs, ecotypes, and species. In theory, ecological discontinuities can impose strong disruptive selection that promotes the evolution of discrete forms, but direct tests ...

Late disruption of central visual field disrupts peripheral perception of form and color

open access: yesPLOS ONE, 2020
Evidence from neuroimaging and brain stimulation studies suggest that visual information about objects in the periphery is fed back to foveal retinotopic cortex in a separate representation that is essential for peripheral perception. The characteristics of this phenomenon have important theoretical implications for the role fovea-specific feedback ...

Roosting ecology and the evolution of pelage markings in bats. [PDF]

open access: yesPLoS ONE, 2011
Multiple lineages of bats have evolved striking facial and body pelage makings, including spots, stripes and countershading. Although researchers have hypothesized that these markings mainly evolved for crypsis, this idea has never been tested in a ...
