Can sexual selection and disassortative mating contribute to the maintenance of a shell color polymorphism in an intertidal marine snail?

open access: yesCurrent Zoology, 2012
Littorina fabalis is an intertidal snail commonly living on the brown algae Fucus vesiculosus and showing frequent shell-color polymorphisms in the wild. The evolutionary mechanism underlying this polymorphism is currently unknown.

Environmental Variation Contributes to Head Phenotypes in Workers of Camponotus japonicus (Hymenoptera: Formicidae)

open access: yesEcology and Evolution
Integrating color polymorphism with intra‐species morphological traits offers substantial opportunities to study the eco‐evolutionary mechanisms underlying local population responses to heterogeneous and dynamic environments.

COLOR POLYMORPHISMS ON COMMON CARP CULTURED IN INDONESIA

open access: yesZuriat, 2015
In most cases, phenotypic variation is partly a result of genetic differences and partly environmental in origin. It appears that polymorphism is caused by some gene frequency changes which are due to natural selection. Morphological markers (body color and scale pattern) are the easiest indicators to identify and important when large sample are ...
