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 …

Sexual dichromatism, a form of sexual dimorphism in which males and females differ in
colour, is widespread in animals but has been predominantly studied in birds, fishes and …

Recent theoretical and empirical studies confirm that male mate choice and/or female–
female mate competition can be expressed in the absence of sex-role reversal. Such …

Melanin is the most widespread pigment in organisms. Melanin-based coloration has been
repeatedly observed to be associated with the same traits and in the same direction in …

Models of sexual selection by mate choice have emphasized the evolution of sexually
dimorphic costly signals, such as elaborate plumage or courtship display, in the sex …

Although melanin is the most common pigment in animal integuments, the adaptive function
of variation in melanin-based coloration remains poorly understood. The individual fitness …

Dynamic sexual dichromatism is a temporary colour change between the sexes and has
evolved independently in a wide range of anurans, many of which are explosive breeders …

Research on the optical properties of animal integuments, including fur, feather, skin and
cuticle, has focussed almost exclusively on animal-visible wavelengths within the narrow …

Elaborate ornamental plumage has been associated with various measures of individual
quality in many species of birds. Male plumage characteristics, which have been relatively …
