Ecological, morphological and phylogenetic correlates of interspecific variation in plasma carotenoid concentration in birds

1 Jan 2004

Abstract excerpt

Carotenoids are important as pigments for bright coloration of animals, and as physiologically active compounds with a wide array of health-related benefits. However, the causes of variation in carotenoid acquisition and physiology among species are poorly known. We measured the concentration of carotenoids in the blood of 80 wild bird species differing in diet, body size and the extent of carotenoid-based...
