Roles of dietary antioxidants and oxidative stress in mediating fitness related traits in birds
… maternal and offspring phenotype and fitness in blue tits Cyanistes caeruleus. I also investigated the role of dietary antioxidants in reducing oxidative stress produced during exercise in adult captive budgerigars Melopsittacus undulatus. Supplementing blue tit parents with [alpha]-tocopherol, a …
