Signal functions of carotenoid colouration
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]).

WebCarotenoid-dependent sexual coloration is one of the best-studied sexual signals, but how the honesty of such signals is maintained remains uncertain. The main hypotheses focus on acquisition limits and physiological use of carotenoids in immune function and regulating oxidative stress. WebThe unique color and type characteristics of watermelon fruits are regulated by many molecular mechanisms. However, it still needs to be combined with more abundant genetic data to fine-tune the positioning. We assembled genomes of two Korean inbred watermelon lines (cv. 242-1 and 159-1) with unique color and fruit-type characteristics and identified …
WebIn several species of Hypocnemis antbirds, acoustic signals function in both intrasexual competition and mate choice. Removal experiments were performed to determine which function takes precedence.
