Journal of Evolutionary Biology, 2008 Several insect species show an increase in cuticular melanism in response to high densities. In some species, there is evidence that this melanism is correlated with an up-regulation of certain immune system components, particularly phenoloxidase (PO ...

On the Melanization of the Rat's Eye
Pigment Cell Research, 1996Electron‐microscopic study of the size of the melanosomes, the mean percentage of melanosomal profile area (MPMA) of the cells, and the duration of melanogenesis in the pigmented layers of the rat's eye (inbred strain BDE/Han) revealed the following: 1) The melanosomes in the cells of the retina vary in size and shape in different locations of the eye.

Is Melanism Adaptive in Sea Kraits?
Amphibia - Reptilia, 2008 International audienceOntogenic melanism (progressive darkening of the skin) has been documented in snakes. Black coloration of the skin often compromises the cryptic effects associated with other patterns (e.g.

Abstract Melanism: Evolution in Action describes investigations into a ubiquitous biological phenomenon, the existence of dark, or melanic, forms of many species of mammals, insects, and some plants. Melanism is a particularly exciting phenomenon in terms of our understanding of evolution.

Abstract The prominence given in biological texts to industrial melanism, and the case of the peppered moth in particular, has tended to eclipse the fact that the majority of British Lepidoptera that now have melanic forms, already had melanic forms prior to the industrial revolution. This must include dark forms which are distributed in

Abstract The Lepidoptera have been pre-eminent in the study of the evolution and maintenance of melanism. However, as mentioned in Chapter 1, there have been many studies of melanism in other groups. Some, such as the work on the spittlebug, Philaneus spunarius, do little more than confirm that evolutionary phenomena, first described in ...

Abstract The ‘colour’ black is a strong motif in life. It conjures dark, mysterious, and fre selves wraiths. Indeed, Shakespeare, in sonnet 147, describes one who has driven their lover to madness and death as being ‘as black as hell’.

Abstract On a sign by a car park at a distillery in Pitlocherie it says: ‘Here you will find more black trees than in the Black Forest’. A quick glance around and the reason for the sign is easy to see. All the trunks, branches and twigs of all the trees and shrubs in the vicinity are as black as soot.
