Fish coloration, evolved from selection and adaptation, is a prominent feature of remarkable
aquaculture merits. Fish possess more pigment cell types than any other vertebrates and are …

African annual fishes from the genus Nothobranchius are small teleosts that inhabit
temporary water bodies subject to annual desiccation due to the alternation of the monsoon …

The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Animal colors play important roles in communication, ecological interactions and speciation.
Carotenoid pigments are responsible for many yellow, orange and red hues in animals …

Polymorphisms have fascinated biologists for a long time, but their genetic underpinnings
often remain elusive. Here, we aim to uncover the genetic basis of the gold/dark …

Chromatophores are pigment-bearing cells of lower vertebrates, including fish that cater for
the ability of individual animals to shift body coloration and pattern. Color change provides …

Yellow mutant rainbow trout (YR), an economically important aquaculture species, is
popular among consumers due to its excellent meat quality and attractive appearance. Skin …

The formation of species in the absence of geographic barriers (ie sympatric speciation)
remains one of the most controversial topics in evolutionary biology. While theoretical …

Species diverge eco-morphologically through the continuous action of natural selection on
functionally important structures, producing alternative adaptive morphologies. In cichlid …

Determining the genetic bases of adaptations and their roles in speciation is a prominent
issue in evolutionary biology. Cichlid fish species flocks are a prime example of recent rapid …
