The effects of dietary linoleic acid and hydrophilic antioxidants on basal, peak, and sustained metabolism in flight trained European Starlings

Wales Carter, Kristen DeMoranville, Barbara Pierce & Scott McWilliams
Dietary micronutrients have the ability to strongly influence animal physiology and ecology. For songbirds, dietary polyunsaturated fatty acids (PUFAs) and antioxidants are hypothesized to be particularly important micronutrients because of their influence on an individual’s capacity for aerobic metabolism and recovery from extended bouts of exercise. However, the influence of specific fatty acids and hydrophilic antioxidants on whole-animal performance remain largely untested. We used diet manipulations to directly test the effects of dietary PUFA, specifically...

Data from: Dietary antioxidants attenuate the endocrine stress response during long-duration flight of a migratory bird

Glucocorticoids (GCs) are metabolic hormones that promote catabolic processes, which release stored energy and support high metabolic demands such as during prolonged flights of migrating birds. Dietary antioxidants (e.g., anthocyanins) support metabolism by quenching excess reactive oxygen species produced during aerobic metabolism, and also by activating metabolic pathways that, similar to GCs’ function, release stored energy, although the extent of complementarity between GCs and dietary antioxidants is not well known. If anthocyanins complement GCs functions,...
