Increasing melanism along a latitudinal gradient in a widespread amphibian: local adaptation, ontogenic or environmental plasticity?

open access: yesBMC Evolutionary Biology, 2010
Background The thermal benefits of melanism in ectothermic animals are widely recognized, but relatively little is known about population differentiation in the degree of melanism along thermal gradients, and the relative contributions of genetic vs ...

Melanism evolution in the cat family is influenced by intraspecific communication under low visibility.

open access: yesPLoS ONE, 2019
Melanism in the cat family has been associated with functions including camouflage, thermoregulation and parasite resistance. Here we investigate a new hypothesis proposing that the evolution of melanism in cats has additionally been influenced by ...

Polymorphism of fur coloration intensity in mammals [PDF]

open access: yesПраці Теріологічної школи, 2016
The concept of coloration polymorphism and melanism in mammals was reviewed. It was shown that polymorphism has different types and mammals color differentiation is only one of its kinds.

A novel locus on chromosome 1 underlies the evolution of a melanic plumage polymorphism in a wild songbird [PDF]

open access: yesRoyal Society Open Science, 2017
Understanding the mechanisms responsible for phenotypic diversification within and among species ultimately rests with linking naturally occurring mutations to functionally and ecologically significant traits.
