Melanism in peromyscus is caused by independent mutations in agouti. [PDF]
PLoS ONE, 2009 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.

Record of melanism in Tamandua tetradactyla (Pilosa: Myrmecophagidae) in Perú
Revista Peruana de Biología, 2022 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.

Revista de Biologia Neotropical, 2021 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

How the leopard hides its spots: ASIP mutations and melanism in wild cats. [PDF]
PLoS ONE, 2012 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

Clinical periodontal diagnosis
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

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.

Mapping black panthers: Macroecological modeling of melanism in leopards (Panthera pardus). [PDF]
PLoS ONE, 2017 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 (
