Preserved melanin pigments have been discovered in fossilised integumentary appendages
of several amniote lineages (fishes, frogs, snakes, marine reptiles, non‐avialan dinosaurs …

Ontogeny is expected to be a determinant factor affecting production of colour patches in
lizards, while immune challenges or sudden weight loss may impair the maintenance of …

Several studies of lizards have made an erroneous interpretation of negative relationships
between spectral brightness and parasite load, and thus provided misleading support for the …

Melanosomes are important organelles melanin is produced stored and mobilized
throughout animal tissues. Melanins confer unique properties to these organelles, including …

With functions as diverse as communication, protection and thermoregulation, coloration is

ABSTRACT Parrots and allies (Order Psittaciformes) have evolved an exclusive capacity to
synthesize polyene pigments called psittacofulvins at feather follicles, which allows them to …

Animals living on the earth's surface are protected from the damaging effects of solar
