1946: The role of natural selection in distribution and dynamics of melanism in common hamster (Cricetus cricetus L.).

Melanism in endangered Mohave tui chub Siphateles bicolor mohavensis Snyder, 1918 (Cypriniformes: Cyprinidae).

The back-wingtip score was doubled because plumage melanism is considered the best way to visually distinguish hybrids from pure birds (Bell 1996).

Sargent (1985) suggested that some melanic moths may be adapted to exploit white backgrounds that are variegated with black, rather than the uniformly dark backgrounds suggested by the traditional explanation of industrial melanism (Kettlewell 1958a).

She also considers the reasons 20th century race researchers placed Asians at the summit of the intelligence racial hierarchy, describes the equally pseudoscientific (if far less celebrated) response of "melanism" researchers who ascribe superior qualities to those with greater melanin, and presents a new way of thinking about intelligence that holistically includes those qualities that race and intelligence researchers tend to ignore.

Ecology becomes central in the second and longest chapter, "A Green Machine," in which a cryptic discussion of the concept of an ecosystem precedes a treatment of standard ecological topics, including adaptation, industrial melanism, the Galapagos finches, niches, and food webs.

This single supergene also appears important in melanism in other species, including moths.

Thus, while thermal melanism may be important for warming the body in some terrestrial organisms (King-solver, 1996; Clusella-Trullas et al, 2007), the importance to gastropods in intertidal systems is less clear.

The melanism of the human prototype is certainly not happenchance.
