Effect of Dietary Carotenoid Supplementation on Food Intake and Immune Function in a Songbird with no Carotenoid Coloration
نویسندگان
چکیده
Carotenoid-based coloration is a common sexually selected trait in birds and fishes (Hill 2006). Their inexorable link to nutrition and their chemical tractability have made carotenoid colors fashionable models for investigating the costs and benefits of sexual features (McGraw 2006). The last decade of work on the signal content of carotenoid colors has uncovered several apparently Correspondence Kevin J.

Dietary carotenoid pigments and immune function in a songbird with extensive carotenoid-based plumage coloration
Carotenoid pigments can directly enhance the immune responses of vertebrates, and they are used by many animals to create ornamental color displays. It has been hypothesized that these two functions of carotenoid pigments are linked: animals must trade off use of carotenoid pigments for immune function versus ornamental display. We tested two key predictions of this hypothesis with captive Amer...
متن کاملA multifactorial test of the effects of carotenoid access, food intake and parasite load on the production of ornamental feathers and bill coloration in American goldfinches.
It has been well established that carotenoid and melanin pigmentation are often condition-dependent traits in vertebrates. Expression of carotenoid coloration in birds has been shown to reflect pigment intake, food access and parasite load; however, the relative importance of and the potential interactions among these factors have not been previously considered. Moreover, carotenoid and melanin...
متن کاملCarotenoid and protein supplementation have differential effects on pheasant ornamentation and immunity.
A currently popular hypothesis states that the expression of carotenoid-dependent sexual ornaments and immune function may be correlated because both traits are positively affected by carotenoids. However, such a correlation may arise for another reason: it is well known that immune function is dependent on nutritional condition. A recent study has suggested that the expression of ornaments may...
متن کاملResearch Article: Effects of different dietary supplementation of plant carotenoids on growth, coloration and behaviour of giant gourami, Trichogaster fasciata (Bloch and Schneider, 1801)
Effects of different dietary supplements of plant carotenoid sources on growth, coloration and behavioural activities of Trichogaster fasciata were carried out. Three groups of fish were fed with petal powder of rose (Rosa chinensis), China rose (Hibiscus rosasinensis) and marigold (Tagetes erecta) separately as carotenoid source along with the same basic ingredients for 90 days. The mean final...
متن کاملCarotenoid-based coloration, condition, and immune responsiveness in the nestlings of a sexually dimorphic bird of prey.
In many birds, nestlings exhibit brightly colored traits that are pigmented by carotenoids. Carotenoids are diet limited and also serve important health-related physiological functions. The proximate mechanisms behind the expression of these carotenoid-pigmented traits are still poorly known, especially in nestlings with sexual size dimorphism. In these nestlings, intrabrood competition levels ...
