Melanins are the ubiquitous pigments distributed in nature. They are one of the main
pigments responsible for colors in living cells. Birds are among the most diverse animals …

Vertebrate pigmentation patterns are amongst the best characterised model systems for
studying the genetic basis of adaptive evolution. The wealth of available data on the genetic …

INTRODUCTION Organisms in the early stages of speciation provide an opportunity to
understand the processes that govern reproductive isolation between taxa. Ecological or …

Bright-red colors in vertebrates are commonly involved in sexual, social, and interspecific
signaling [1–8] and are largely produced by ketocarotenoid pigments. In land birds …

Parrot feathers contain red, orange, and yellow polyene pigments called psittacofulvins.
Budgerigars are parrots that have been extensively bred for plumage traits during the last …

A review is presented of the seven commonest types of colour aberrations in birds together
with suggestions for a standardised universal nomenclature to identify and distinguish these …

Recent genomic analyses of evolutionary radiations suggest that ancestral or standing
genetic variation may facilitate rapid diversification, particularly in cases involving …

SLC45A2 encodes a putative transporter expressed primarily in pigment cells. SLC45A2
mutations cause oculocutaneous albinism type 4 (OCA4) and polymorphisms are …

Existing methods for identifying structural variants (SVs) from short read datasets are
inaccurate. This complicates disease-gene identification and efforts to understand the …

Hybrid zones are geographic regions where differentiated taxa meet and potentially
exchange genes. Increasingly, genomic analyses have demonstrated that many hybrid …
