- Red coloration varies with dietary carotenoid access and nutritional condition in kittiwakes
Summary: The main mechanism limiting the full expression of carotenoid-based color signals varies with environmental conditions in a red-colored seabird.
- An in vivo test of the biologically relevant roles of carotenoids as antioxidants in animals
Summary: When given an oxidative challenge, copepods deprived of carotenoids show higher oxidative damage and mortality than carotenoid-restored copepods.
