Shell color polymorphism in marine gastropods [PDF]

open access: yesEvolutionary Applications, 2023
Marine gastropods are characterized by an incredible variation in shell color. In this review, we aim to introduce researchers to previous studies of shell color polymorphism in this group of animals, trying to provide an overview of the topic and ...

Flower color polymorphism of a wild Iris on the Qinghai-Tibet plateau [PDF]

open access: yesBMC Plant Biology, 2023
Background Flower color plays a crucial role in attracting pollinators and facilitating environmental adaptation. Investigating the causes of flower color polymorphism and understanding their potential effects on both ecology and genetics can enhance our

Complete Mitochondrial Genomes of Nedyopus patrioticus: New Insights into the Color Polymorphism of Millipedes [PDF]

open access: yesCurrent Issues in Molecular Biology
There has been debate about whether individuals with different color phenotypes should have different taxonomic status. In order to determine whether the different color phenotypes of Nedyopus patrioticus require separate taxonomic status or are simply ...

Aposematic color polymorphism is a poor indicator of species boundaries in North American Paranthrene (Lepidoptera: Sesiidae) as evidenced by a multi-gene phylogeny. [PDF]

open access: yesPLoS ONE
Color polymorphism among animal species can influence speciation. Factors such as natural and sexual selection, genetic drift and gene flow contribute to the maintenance of color polymorphism within the species or spur speciation.

Structural background of intraspecific color polymorphism and the driver of geographic patterns in a shining leaf chafer [PDF]

open access: yesFrontiers in Zoology
Background The phenomenon of color polymorphism has been extensively documented in a range of animal species. A series of hypotheses have been proposed to explain potential functions of color variations in diverse habitats.

Reproductive trade-offs maintain bract color polymorphism in Scarlet Indian paintbrush (Castilleja coccinea). [PDF]

open access: yesPLoS ONE, 2019
Populations of scarlet Indian paintbrush (Castilleja coccinea) in the Midwestern United States exhibit a bract color polymorphism, with each population having predominantly yellow or scarlet bracts.

Mixed signals? Morphological and molecular evidence suggest a color polymorphism in some neotropical polythore damselflies. [PDF]

open access: yesPLoS ONE, 2015
The study of color polymorphisms (CP) has provided profound insights into the maintenance of genetic variation in natural populations. We here offer the first evidence for an elaborate wing polymorphism in the Neotropical damselfly genus Polythore, which

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 ...

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 ...
