The study of coloration in the polyphyletic reptilians has flourished in the last two decades, in
particular with respect to the underlying genetics of colour traits, the function of colours in …

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

A long-standing hypothesis in evolutionary ecology is that red–orange ornamental colours
reliably signal individual quality owing to limited dietary availability of carotenoids and …

Carotenoids typically need reflective background components to shine. Such components,
iridophores, leucophores, and keratin-and collagen-derived structures, are generally …

Ornamental colours usually evolve as honest signals of quality, which is supported by the
fact that they frequently depend on individual condition. It has generally been suggested that …

Why do some invertebrates store so much carotenoids in their tissues? Storage of
carotenoids may not simply be passive and dependent on their environmental availability …

Carotenoid-based sexual ornaments are widespread, but the role of carotenoids as honest
signalers in the trade-off between coloration and antioxidant protection remains …

Environmental and ecological conditions can shape the evolution of life history traits in many
animals. Among such factors, food or nutrition availability can play an important evolutionary …

Male lizards often display multiple pigment‐based and structural colour signals which may
reflect various quality traits (eg performance, parasitism), with testosterone (T) often …

The diversity of sexual signals is astounding, and divergence in these traits is believed to be
associated with the early stages of speciation. An increasing number of studies also suggest …
