Melanism in Peromyscus Is Caused by Independent Mutations in Agouti [PDF]
Identifying the molecular basis of phenotypes that have evolved independently can provide insight into the ways genetic and developmental constraints influence the maintenance of phenotypic diversity.

How the Leopard Hides Its Spots: ASIP Mutations and Melanism in Wild Cats [PDF]
The occurrence of melanism (darkening of the background coloration) is documented in 13 felid species, in some cases reaching high frequencies at the population level. Recent analyses have indicated that it arose multiple times in the Felidae, with three

Mapping Black Panthers: Macroecological Modeling of Melanism in Leopards (Panthera pardus) [PDF]
The geographic distribution and habitat association of most mammalian polymorphic phenotypes are still poorly known, hampering assessments of their adaptive significance. Even in the case of the black panther, an iconic melanistic variant of the leopard (

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 ...

Recurrent Evolution of Melanism in South American Felids
Morphological variation in natural populations is a genomic test bed for studying the interface between molecular evolution and population genetics, but some of the most interesting questions involve non-model organisms that lack well annotated reference

First Locality Record of Melanistic Oncilla (Leopardus tigrinus) in Monteverde, Costa Rica [PDF]
The persistence of the coat color polymorphism melanism has been reported for several tropical felids, but its evolutionary advantages remain an active area of research.

An Opposite Pattern to the Conventional Thermal Hypothesis: Temperature-Dependent Variation in Coloration of Adults of Saccharosydne procerus (Homoptera: Delphacidae). [PDF]
Melanism is a common polymorphism in many insect species that also influences immune function. According to the thermal melanin hypothesis, ectothermic individuals from cooler environments have darker cuticles and higher polyphenol oxidase (PO) levels ...

Insular organisms often evolve predictable phenotypes, like flightlessness, extreme body sizes, or increased melanin deposition. The evolutionary forces and molecular targets mediating these patterns remain mostly unknown.

Melanism can represent examples of adaptive evolution such as camouflage and thermoregulation, which can determine the explored habitat and the periods of greatest activity of felines with this phenotype. Despite being considered relatively common, cases

Record of melanism in Tamandua tetradactyla (Pilosa: Myrmecophagidae) in Perú
A case of melanism in Tamandua tetradactyla (Myrmecophagidae) is recorded, based on an individual observed in the Huánuco Department, Peru. Two previous records are found in the iNaturalist database.
