Color polymorphisms offer unique opportunities for testing the role of ecological adaptation and natural selection in the origin of species. However, the ecological conditions that facilitate the coexistence and speciation of color morphs in nature ...

Spectral Sensitivities and Color Signals in a Polymorphic Damselfly
Animal communication relies on conspicuous signals and compatible signal perception abilities. Good signal perception abilities are particularly important for polymorphic animals where mate choice can be a challenge. Behavioral studies suggest that polymorphic damselflies use their varying body colorations and/or color patterns as communication signal ...

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 ...

Nuclear Gene Indicates Coat-Color Polymorphism in Mammoths [PDF]
By amplifying the melanocortin type 1 receptor from the woolly mammoth, we can report the complete nucleotide sequence of a nuclear-encoded gene from an extinct species. We found two alleles and show that one allele produces a functional protein whereas the other one encodes a protein with strongly reduced activity.

Human activities are increasingly confronting animals with unfamiliar environmental conditions. For example, habitat change and loss often lead to habitat fragmentation, which can create barriers of unsuitable and unfamiliar habitat affecting animal ...

Explaining the evolutionary origin and maintenance of color polymorphisms is a major challenge in evolutionary biology. Such polymorphisms are commonly thought to reflect the existence of alternative behavioral or life‐history strategies under negative ...

Selection's Role in Maintaining a Color Polymorphism in the Sulawesi Fish Telmatherina antoniae
Explaining the extraordinary genetic variation present in natural populations is a central and longstanding problem of evolutionary biology. Color polymorphisms have proven to be powerful models for studying how genetic variation, associated with ...
