Data from: Proximate mechanisms of colour variation in the frillneck lizard: geographical differences in pigment contents of an ornament

Thomas Merkling, David G. Hamilton, Borbala Cser, Nina Svedin & Sarah R. Pryke
Animal coloration has evolved in contexts such as communication, camouflage, and thermoregulation. Most studies of animal coloration focus on its adaptive benefits, whereas its underlying mechanisms have received less attention despite their potential influence on adaptive benefits. In fish and reptiles, for example, colour variation from yellow to red can be produced by carotenoid and/or pteridine pigments, which differ dramatically in the way they are obtained (carotenoids through diet and pteridines synthesized de novo). Hence,...
