Here, we review the recently burgeoning literature on color polymorphisms, seeking to
integrate studies of the maintenance of genetic variation and the evolution of reproductive …

The hypothesis that ornaments can honestly signal quality only if their expression is
condition-dependent has dominated the study of the evolution and function of colour traits …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Synopsis “Sex” is often used to describe a suite of phenotypic and genotypic traits of an
organism related to reproduction. However, these traits—gamete type, chromosomal …

Melanins are a ubiquitous component of plumage colouration in birds and serve a wide
variety of functions. Although the genetic control of melanism has been studied in chickens …

To ensure long-term persistence, organisms must adapt to climate change, but an
evolutionary response to a quantified selection pressure driven by climate change has not …

Colour polymorphism exemplifies extreme morphological diversity within populations,. It is
taxonomically widespread but generally rare. Theory suggests that where colour …

Polymorphic species, in which multiple variants coexist within a population, are often used
as model systems in evolutionary biology. Recent research has been dominated by the …

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

Establishing the links between phenotype and genotype is of great importance for resolving
key questions about the evolution, maintenance and adaptive function of phenotypic …
