Sex-specific morphs exhibit discrete phenotypes, often including many disparate traits, that
are observed in only one sex. These morphs have evolved independently in many different …

Colour polymorphic species are model systems for examining the evolutionary processes
that generate and maintain discrete phenotypic variation in natural populations. Lizards …

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors.
These conspicuous colors serve a diversity of signaling functions, but their molecular basis …

Color polymorphism defies evolutionary expectations as striking phenotypic variation is
maintained within a single species. Color and other traits mediate social interactions, and …

Determining the mechanistic and genetic basis of animal coloration is essential to
understand the costs and constraints on color production, and the evolution and …

Australian lizards are a diverse group distributed across the continent and inhabiting a wide
range of environments. Together, they exhibit a remarkable diversity of reproductive …

Biologists have long tried to describe and name the different phenotypes that make up the
shell polymorphism of the land snail Cepaea nemoralis. Traditionally, the view is that the …

In the animal kingdom, sexually dimorphic color variation is a widespread phenomenon that
significantly influences survival and reproductive success. However, the genetic …

Stress is an important potential factor mediating a broad range of cellular pathways,
including those involved in condition‐dependent (ie, honest) color signal expression …

Color polymorphism often is associated with alternative reproductive strategies and may
reflect different adaptive optima that coexist within populations. The equilibrium among …
