Estimation of Selection Intensity Against Dark Color Forms of the Spittlebug Philaenus spumarius (L.) in a Warming Climate [PDF]

open access: yesInsects
Climate warming puts new selective pressures on natural populations, but there are few quantitative measurements of selection in natural populations over protracted time periods.

Trait differences among discrete morphs of a color polymorphic lizard, Podarcis erhardii [PDF]

open access: yesPeerJ, 2020
Color polymorphism defies evolutionary expectations as striking phenotypic variation is maintained within a single species. Color and other traits mediate social interactions, and stable polymorphism within a population is hypothesized to be related to ...

Color polymorphism and variation in microhabitat selection: a defensive strategy in males of Boana pulchella (Anura: Hylidae)?

open access: yesActa Scientiarum: Biological Sciences, 2022
Anurans vary in body coloration and frequently exhibit color polymorphism, with selection by predation pressure favoring more cryptic animals. Spatial differentiation may also favor color polymorphism in some species, since cryptic morphotypes can use ...

Colorful DNA polymorphisms in humans [PDF]

open access: yesSeminars in Cell & Developmental Biology, 2013
In this review article we summarize current knowledge on how variation on the DNA level influences human pigmentation including color variation of iris, hair, and skin. We review recent progress in the field of human pigmentation genetics by focusing on the genes and DNA polymorphisms discovered to be involved in determining human pigmentation traits ...

Dominant gingers – Discovery and inheritance of a new shell polymorphism in the great pond snail Lymnaea stagnalis

open access: yesEcology and Evolution, 2023
Color polymorphism is a classic study system for evolutionary genetics. One of the most color‐polymorphic animal taxa is mollusks, but the investigation of the genetic basis of color determination is often hindered by their life history and the limited ...

Individual Variation in Dietary Wariness Is Predicted by Head Color in a Specialist Feeder, the Gouldian Finch

open access: yesFrontiers in Ecology and Evolution, 2021
Shifts in resource availability due to environmental change are increasingly confronting animals with unfamiliar food types. Species that can rapidly accept new food types may be better adapted to ecological change.

Color Polymorphs of ROY-ol

open access: yesCrystal Growth & Design, 2022
Color polymorphism is a fascinating property exhibited by compounds that have polymorphs of different colors. The most famous family of substances forming molecular organic color polymorphs is the ROY family of compounds. ROY, which states for the red, orange, and yellow colors of the polymorphs of 5-methyl-2-((2-nitrophenyl)amino)thiophene-3 ...

Ontogeny of color development in two green–brown polymorphic grasshopper species

open access: yesEcology and Evolution, 2023
Many insects, including several orthopterans, undergo dramatic changes in body coloration during ontogeny. This variation is particularly intriguing in gomphocerine grasshoppers, where the green and brown morphs appear to be genetically determined ...
