Signal functions of carotenoid colouration
WebThe importance of carotenoids for natural colouration, in relation to other classes of pigments and structural colours, has been outlined in Chapter 10.

However, it is unclear whether BCDO2 is involved in the …
WebIn animals, coloration, via both pigmentation and nanos-tructure, has many functions. For example, it is often used for intraspecific communication (e.g. ornamental color used for mate choice and intrasexual competition [6,15– 18]) and interspecific interactions (e.g. aposematic and cryptic coloration used for predator avoidance [6,15,19]).
