Abstract Feathers tend to be darkly colored in habitats where relative humidity is high and pale where it is low. We suggest that this correlation, known as Gloger's rule, results, in part, from selection for dark feathers that are more resistant than light feathers to bacterial degradation, which is a severe problem in humid habitats where bacteria thrive and a lesser problem in arid habitats. In May and June 2000–2002 we sampled feather-degrading bacteria (Bacillus licheniformis) from the… 
Variation in Assemblages of Feather Bacteria in Relation to Plumage Color in Female Great Tits
TLDR
Findings suggest that conspicuous coloration of female Great Tits may reflect the numbers and character of bacteria inhabiting feathers, and negatively related to the phylotypic richness of feather-degrading bacteria.
Interactions between Feather-Degrading Bacteria and Feather Coloration
PAGE Bacteria that can damage feathers have been isolated from the plumage of several avian species. These feather-degrading bacteria (FDB) may contribute to feather wear and could thus influence
Colourful parrot feathers resist bacterial degradation
TLDR
Differences in resistance to bacterial degradation of differently coloured feathers suggest that colour patterns within the Psittaciformes may have evolved to resist bacterial degradation, in addition to their role in communication and camouflage.
Feather-degrading bacilli in the plumage of wild birds: Prevalence and relation to feather wear
TLDR
The presence of feather-degrading bacilli, but not the abundance of bacteria in general, was correlated with the measure of plumage condition, suggesting that the presence of these bacteria is related to degradation of feathers in wild birds.
Gloger's rule in plants: The species and ecosystem levels
  • S. Lev-Yadun
  • Biology, Medicine
    Plant signaling & behavior
  • 2015
TLDR
Both Gloger and “anti-Gloger” cases are presented and it is argued that this largely neglected aspect of plant biology deserves much more research attention.
Seasonally Changing Preen-Wax Composition: Red Knots' (Calidris Canutus) Flexible Defense Against Feather-Degrading Bacteria
TLDR
It is suggested that preen waxes protect feathers by forming a physical barrier to microbes rather than through chemical properties of the waxes.
Pig pigmentation: testing Gloger's rule
Comparative studies indicate that several mammalian clades obey Gloger's rule in that they exhibit darker coloration in humid warm climates, although the mechanisms responsible for this association
A feather ecosystem: The prevalence of feather-degrading bacilli in the plumage of birds
The study of keratinolytic microorganisms in avian plumage is a rapidly growing, but still poorly understood field. While the bulk of this research has focused on possible selection pressures, we
Increased plumage darkness of female Shiny Cowbirds Molothrus bonariensis in the subtropics: an adaptation to bacterial degradation?
TLDR
It is suggested that female plumage polymorphism in Shiny Cowbirds has not arisen as a defence against bacterial feather-degrading activity, and differences in susceptibility to bacterial degradation between brown feathers and darker feathers are found.
Feather-degrading bacteria from the plumage of Neotropical Spectacled Thrushes (Turdus nudigenis)
ABSTRACT We studied the diversity and abundance of keratinolytic bacteria hosted by the plumage of Spectacled Thrushes (Turdus nudigenis), and their capacities to break down feathers in vitro. From

Occurrence of feather-degrading bacilli in the plumage of birds
TLDR
It is suggested that feather degradation may contribute to the deterioration of feathers and be a selective force in the evolution and timing of molt during the summer when the bird becomes wet, for example during thunderstorms.
CAROTENOID PIGMENTS IN MALE HOUSE FINCH PLUMAGE IN RELATION TO AGE, SUBSPECIES, AND ORNAMENTAL COLORATION
TLDR
Improved analytical techniques were used to describe types and amounts of carotenoid pigments present in male House Finches' plumage, and a distinctive pigment profile for each age group within each subspecies was found.
BACTERIAL DEGRADATION OF BLACK AND WHITE FEATHERS
TLDR
The differential absorption of light supports the conclusion that B. licheniformis degrades white feathers more rapidly than black feathers.

TLDR
Chemical analysis of melanin pigments in feather germs of Bh mutant embryos and in feathers of adult animals suggest that the Bh mutation causes pheomelanic changes in feathersof quails.

Isolation, Identification, and Characterization of a Feather-Degrading Bacterium
TLDR
A feather-degrading culture was enriched with isolates from a poultry waste digestor and adapted to grow with feathers as its primary source of carbon, sulfur, and energy, indicating a potential biotechnique for degradation and utilization of feather keratin.

MELANIN ORNAMENTS, HONESTY, AND SEXUAL SELECTION
TLDR
It is demonstrated that the color diversity of melanin ornaments is quite broad, including red, orange, yellow, and green, in addition to black and brown, and it is perhaps incorrectly assumed that melaninOrnaments are typically black or blackish-brown and thus show both less variation within species and less diversity across species than do carotenoids.
Plumage coloration and nutritional condition in the great tit Parus major: the roles of carotenoids and melanins differ
TLDR
The size and coloration of some body characters seem to influence mate choice in many species, but the results suggest that the expression of the two traits may be regulated by different mechanisms.
