Ecology 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.

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

Color-assortative mating in a color-polymorphic lacertid lizard [PDF]
Behavioral Ecology, 2012 Color polymorphisms are common in lizards, which provide an excellent model system to study their evolution and adaptive function. The lacertid genus Podarcis is particularly interesting because it comprises several polymorphic species. Previous studies with lacertid lizards have tried to explain the maintenance of color polymorphisms by correlational ...

The Biology of Polymorphic Melanic Side-Spotting Patterns in Poeciliid Fishes
Frontiers in Ecology and Evolution, 2021 Melanin-based color patterns are an emerging model for studying molecular and evolutionary mechanisms driving phenotypic correlations. Extensive literature exists on color patterns and their correlated traits in the family Poeciliidae, indicating that ...

On Venezuelan pholcid spiders (Araneae, Pholcidae)
European Journal of Taxonomy, 2020 We present a comprehensive revision of the pholcid spider collection of M.A. González-Sponga, who between 1998 and 2011 described 22 new genera and 51 new species of Pholcidae from Venezuela.

Causes and Consequences of Color Polymorphism [PDF]
, 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.

Green‐brown polymorphism in alpine grasshoppers affects body temperature
Ecology and Evolution, 2020 Ectothermic animals depend on external heat sources for pursuing their daily activities. However, reaching sufficiently high temperature can be limiting at high altitudes, where nights are cold and seasons short.

Introgression drives repeated evolution of winter coat color polymorphism in hares. [PDF]
Proc Natl Acad Sci U S A, 2019 Changing from summer-brown to winter-white pelage or plumage is a crucial adaptation to seasonal snow in more than 20 mammal and bird species. Many of these species maintain nonwhite winter morphs, locally adapted to less snowy conditions, which may have

Pigments of a color polymorphism in a cichlid fish
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973 Abstract 1. 1. Cichlasoma citrinellum occurs as gray or gold morphs in lakes in Nicaragua. The gold morph is variable and individuals range from yellow to dark orange. 2. 2. The pigments responsible for the carotenoid coloration are e-carotene and canthaxanthin. The gray morph contains a carotenoid component and also heavy melanin deposits.
