The Genetic Basis of Melanism in Abert’s Squirrel (Sciurus aberti)
AnimalsMelanism is widespread in different taxa and has been hypothesized to provide adaptive benefits in certain environments. Melanism is typically caused by mutations in one of two regulatory genes: the Melanocortin 1 Receptor (MC1R) or the Agouti Signaling ...

Melanism in cats; The fascinating phenomenon of melanism in big cats
, 2023 What is melanism in big cats? Melanism is a genetic condition that results in increased production of dark pigmentation in the skin, coat and eyes of animals. In big cats, this condition can result in an all-black coat called melanistic. This is caused by a mutation in the genes responsible for the production of melanin, the pigment that gives color to

Multiple origins of melanism in two species of North American tree squirrel (Sciurus) [PDF]
BMC Evolutionary Biology, 2019 Background While our understanding of the genetic basis of convergent evolution has improved there are still many uncertainties. Here we investigate the repeated evolution of dark colouration (melanism) in eastern fox squirrels (Sciurus niger; hereafter “

Comparative Analysis of Transcriptomes among Bombyx mori Strains and Sexes Reveals the Genes Regulating Melanic Morph and the Related Phenotypes. [PDF]
PLoS ONE, 2016 As a source of insect polymorphism, melanism plays an important role in ecological adaption and usually endows advantageous phenotypic-effects on insects.

Experimental manipulation of melanism demonstrates the plasticity of preferred temperature in an agricultural pest (Phaulacridium vittatum). [PDF]
PLoS ONE, 2013 Phenotypic plasticity is a key trait of successful pest species, and may increase the ability to cope with higher, more variable temperatures under climate change.

Melanism in a larval Lepidopteran : repeatability and heritability of a dynamic trait.
, 2006 1. Although it is well established that the deposition of melanin pigment in the cuticle of larval Lepidoptera is influenced by both environmental and genetic factors, few studies have examined intra-individual regional variation in the degree of ...

The Canadian Entomologist, 1891 At different times considerable attention has been paid to the general darkening in colour of our British insects, compared with Centrall European and with American forms. In Britian, many species become much darker(some absolutely black) on various parts of the West Coasts of Ireland and Great Britian, and, as a general rule, the more humid districts ...

Effect of melanism of alpine Colias nastes butterflies (Lepidoptera: Pieridae) on activity and predation [PDF]
, 2006 : Melanism in the Sulphur butterfly Colias nastes Boisduval was quantified and related to their ability to remain active under cool or cloudy conditions and to their risk of predation.

Parallel evolution of urban–rural clines in melanism in a widespread mammal
Scientific Reports, 2022 Urbanization is the dominant trend of global land use change. The replicated nature of environmental change associated with urbanization should drive parallel evolution, yet insight into the repeatability of evolutionary processes in urban areas has been
