Gloger's rule is an ecogeographical rule that links animal colouration with climatic variation.
This rule is named after CWL Gloger who was one of the first to summarise the associations …

Colour patterns are prominent features of many animals and have important functions in
communication, such as camouflage, kin recognition and mate choice. As targets for natural …

Birds are the most species-rich class of tetrapod vertebrates and have wide relevance
across many research fields. We explored bird macroevolution using full genomes from 48 …

Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Genetic colour polymorphisms are widespread across animals and often subjected to
complex selection regimes. Traditionally, colour morphs were used as simple visual markers …

The colorful phenotypes of birds have long provided rich source material for evolutionary
biologists. Avian plumage, beaks, skin, and eggs—which exhibit a stunning range of cryptic …

Animal colors play important roles in communication, ecological interactions and speciation.
Carotenoid pigments are responsible for many yellow, orange and red hues in animals …

Birds and other vertebrates display stunning variation in pigmentation patterning, yet the
genes controlling this diversity remain largely unknown. Rock pigeons (Columba livia) are …

Gloger's rule is usually interpreted as predicting darker coloured animals in warmer and
more humid/vegetated regions. The relative importance of temperature and rainfall or …
