متن کاملHow feather colour reflects its carotenoid content
1. Many birds sequester carotenoid pigments in colourful patches of feathers to advertise or compete for mates. Because carotenoids can be scarce in nature and serve valuable physiological functions, only the highest-quality individuals are thought to acquire or allocate more pigments for use in sexual displays. 2. A critical but rarely tested assumption of carotenoid-based signals is that the ...
متن کاملHow feather colour reflects its melanin content
1. Melanin coloration is the most common type of colour in animals. Many species use melanin-based black, brown, grey or earth-toned colours as intraspecific signals of quality. 2. Melanin comes in two main forms in vertebrates – eumelanin and phaeomelanin – and these are said to create different colours, with eumelanin giving a darker black, brown or grey appearance and phaeomelanin a lighter ...
متن کاملHow dewlap color reflects its carotenoid and pterin content in male and female brown anoles (Norops sagrei).
Sexually selected colors in animals can be created by multiple pigments (e.g., carotenoids, melanins, pterins), but how these pigment classes interact to generate intraspecific color variation has rarely been tested, especially in reptiles. We examined full-spectrum color variation as well as pterin (i.e., drosopterin) and carotenoid (i.e., xanthophyll) pigment concentrations in the yellow and ...
متن کاملDietary carotenoid availability, sexual signalling and functional fertility in sticklebacks
In species where males express carotenoid-based sexual signals, more intensely coloured males may be signalling their enhanced ability to combat oxidative stress. This may include mitigating deleterious oxidative damage to their sperm, and so be directly related to their functional fertility. Using a split-clutch in vitro fertilization technique and dietary carotenoid manipulation, we demonstra...
