Gray plumage color is more cryptic than brown in snowy landscapes in a resident color polymorphic bird

open access: yesEcology and Evolution, 2020
Camouflage may promote fitness of given phenotypes in different environments. The tawny owl (Strix aluco) is a color polymorphic species with a gray and brown morph resident in the Western Palearctic.

PMEL p.Leu18del dilutes coat color of Kumamoto sub-breed of Japanese Brown cattle

open access: yesBMC Genomics, 2022
Background Coat color is important for registration and maintenance of livestock. Standard coat color of Kumamoto sub-breed of Japanese Brown cattle is solid brown, but individuals with diluted coat color have been observed recently.

Does color matter? Molecular and ecological divergence in four sympatric color morphs of a coral reef fish

open access: yesEcology and Evolution, 2020
Non‐sex‐linked color polymorphism is common in animals and can be maintained in populations via balancing selection or, when under diversifying selection, can promote divergence.

Color polymorphism is a driver of diversification

open access: yes, 2021
Color polymorphism – two or more heritable color phenotypes maintained within a single breeding population – is an extreme type of intra-specific diversity widespread across the tree of life.

Negative frequency‐dependent selection maintains shell banding polymorphisms in two marine snails (Littorina fabalis and Littorina saxatilis)

open access: yesEcology and Evolution, 2021
The presence of shell bands is common in gastropods. Both the marine snails Littorina fabalis and Lttorina saxatilis are polymorphic for this trait. Such polymorphism would be expected to be lost by the action of genetic drift or directional selection ...

Enclosure Background Preferences Differ between Sexes and Color Morphs in the Gouldian Finch

open access: yesAnimals, 2023
Most wild animals camouflage well into their environment, providing protection from predators, whereas captive animals often contrast with their background. This can cause stress for the animal, which may perceive it as being exposed.

Causes and Consequences of Color Polymorphism [PDF]

open access: yes, 2021
One hundred and fifty years after Darwin and “On the Origin of Species,” understanding how phenotypic variation is generated, maintained, and lost remains a central goal in evolutionary biology.

Evolutionary history and diversity in the ball roller beetle Canthon cyanellus

open access: yesFrontiers in Ecology and Evolution, 2023
To understand the evolutionary history of species, it is necessary to know the mechanisms for reproductive isolation, divergence-time between populations, and the relative action of the evolutionary forces (e.g., mutation, genetic drift, gene flow ...

Maintenance of polymorphism in the orb weaving spider species Agalenatea redii (Araneae, Araneidae) [PDF]

open access: yes, 2012
The maintenance of polymorphism within populations may be the consequence of several elements of species life history such as use of space, activity rhythms, predation, parasitism and reproduction.
